PREFACE.
This work is not meant to be a theory of harmony, but a simple
practical system, by means of which a knowledge of the mass of facts
that form the basis of the art of composition may be acquired. Theo-
retical questions are therefore carefully avoided, and the tempered
scale is accepted as the foundation of modern music.
The principal assumption or hypothesis upon which the system is
built is the following :
No scale is an independent entity, but is only the principal one
in a group of six called the related group.
The other is the reference of all dissonant groups to two roots in
each scale.
The related group is of course familiar to all musicians, but it has
never been used as the basis of a system of teaching harmony, to any
great extent. The derivation of dissonarit groups from a few roots
is also quite familiar now, yet some departures from the usual manner
of treating them will be found in this work, not for theoretical rea-
sons, but for the gain of greater simplicity.
The plan of teaching laid down in this work is entirely new in
several respects, and is based on the following maxims :
Teach one thing at a time.
Arrange the subject matter in such way that each step is a natural
outgrowth of the last.
Teach the pupil how to use his knowledge, instead of simply try-
ing to follow out the rule. Another departure from the usual prac-
tice is the complete discarding of the figured bass, with the result
that all merely mechanical rotework is eliminated, and the pupil
writes the chords because he knows what they are.
Many of the rules usually found in text-books are omitted ; many
of them are modified. For the reason that the so-called rules of
PREFACE.
composition have all been arrived at empirically, they are in a great
measure, and ought to be altogether, deductions from the practice of
those best qualified to say what should or should not be; viz., the
great composers. It is a common subject of complaint on the part
of the student that such and such things are laid down in the text-
books as rules that must not be broken, and when he turns to the
work of some great composer he finds them totally disregarded. His
complaint is generally met by the reply, "When you can write like
so and so, you may break the rules also." A wiser reply would be,
Whatever has been sanctioned by a great writer becomes the property
of all, provided they can use it with taste and discretion.
We do not wish to be understood as recommending to the pupil
the instant disregard of all rules, because no one can learn how to
break them until he has learned thoroughly well how to use them.
It being the business of harmony to teach the combinations and
succession of sounds, very little is said in this book about the move-
ment of parts, that being the province of counterpoint, which may
be defined as the art of making the best use of the materials placed
at our disposal by harmony.

INTRODUCTION.
Sound is produced by the motion of the air. This motion is com-
municated to it by the vibration of some material body. If the vibra-
tions are irregular, the sound produced is called Noise ; if they are
regular, the sound produced is called Musical.
The means used for producing musical sounds for artistic purposes
are :
ist. The vibration of a Column of Air enclosed in a tube, as in the
flute and the flue-pipes of the organ.
2d. The combination of the column of air with a Reed, as in the
clarinet, hautboy, and ( in some degree ) the human voice.
3d. The vibration of Strings set in motion by the fingers, or by a
bow, or by hammers, as in the harp, violin, and piano. The brass in-
struments may be included among the reed instruments, as the lip of
the player in this case performs the function of the reed.
4th. The vibration of the free reed, as in the harmonium.
Musical sounds are distinguished among themselves in various
ways :
ISt. As high or low ( acute or grave ) , called Pitch.
2d. Loud and soft (forte and piano), called Intensity.
3d. Quality (timbre). By quality is meant that property of a
musical sound by which we distinguish whether it is produced by a
violin, or flute, or voice, etc.
4th. By the relative length of time the sounds last, called Du-
ration.
Notation is a system of signs designed to represent the Pitch, Du-
ration, and Intensity of sounds.
The signs used to designate Pitch are the Staff and the Clefs; to
designate Duration, the Notes ;

IN TROD UC TION.
To designate Pitch and Duration together, the Position of the
Notes on the Staff and their Form.
The Staff consists of five parallel lines, on, between, and above or
below which the notes are placed. When the staff is insufficient, addi-
tional lines called Leger Lines ( generally but erroneously written
ledger ) are used, and the notes are written on, between, above, or
below them.
The Clefs, three in number, are placed at the beginning of the staff ;
they determine the letter name of the line upon which they are placed.
ist. The treble or G clef, used now only on the second line.
2d. The C clef, Sr or use d on the first line, is called the
soprano or descant clef ; on the third line, called the Alto Clef ; and
on the fourth line, called the Tenor Clef. The use of this clef on the
first line is gradually being discontinued.
3d. The Bass or F clef, CJj, used now only on the fourth line,
was formerly used on the third line also, and then called the baritone
clef.
The Pitch of the G indicated by is that of the sound given by
an open pipe sixteen inches long ; of the C indicated by that of
one twenty-four inches long ; of the F indicated by ^f, that of one
thirty-six inches long.
In vocal music the use of the G clef for the tenor voice has become
almost universal. When so used its Pitch must be understood as
being an octave lower; viz., that of the sound produced by a pipe
thirty-two inches long.
The Forms of notes indicate their relative duration ; their Positions
on the staff their letter names.
Eight forms of notes are used ; the duration of each is half that of
the one that precedes it. The first and last forms are less used
than the others ; they are named :
Breve, or Whole Half Quarter Eighth Sixteenth Thirty-sec- Sixty-fourth
double whole note. note. note. note. note. note. ond note. note.

Dots modify the duration of rests in the same way as that of notes.
The essential rhythm of music is indicated by dividing it into por-
tions of equal duration by lines drawn across the staff, called Bars.
The enclosed spaces are called Measures, but in ordinary speech are
also called bars.
To indicate the rhythmic content of the measure, signs called
Time Signatures are placed after the clef ; these are the following :

INTRODUCTION.
The lower figure indicates the note taken as the unit of the beat or
pulse \ the upper figure, the number of these units that each measure
must contain.
The first two signs, and g, are survivals of the old sign for
what was called imperfect time ; viz., a broken circle, which signified
two beats in the measure. The first of these signs, |Jj, always means
two beats in the measure, and is called alia breve time ; the g with-
out the line is the same as i. e., four beats in the measure.
The first four are called Simple Common Time. Common time
means an even number of beats in a measure ; simple means that
a single rhythmic unit is contained in each measure, (g or ^ is,
strictly speaking, a compound of two rhythmic units, but custom includes it among the simple
times.)
The second four are called Simple Triple Time because each meas-
ure contains three beats, or one rhythmic unit of 1, 2, 3.
The Compound Times are all made from Simple Triple Time. If
the upper figure is 6, it signifies that two measures of simple triple
are made into one; if the upper figure is 12, four measures of simple
triple are made into one. Then, as 6 and 12 are even numbers, it is
called Compound Common Time.
The last four consist of three measures of triple time made into
one; and as the upper figure is the odd number 9, it is called Com-
pound Triple Time.
A Scale is a succession of sounds ascending or descending from a
given sound. There are two kinds of scale, Diatonic and Chromatic.
A Diatonic Scale moves through the letters without omission or
repetition. A Chromatic Scale repeats the letters, changing their
pitch by means of signs called sharp ($), flat (b), natural (fc[), double
sharp (x), double flat (bb).
The interval between a given letter and the next above or below is
called a whole tone if another sound comes between them, and a half
tone if no sound comes between them. Natural half-tones are found
between E and J?, and B and C; in every other case, if a half-tone
is desired between two letters, one or the other must be modified in
pitch by means of a sharp or flat.
IN TR ODUC TJON.

The sharp raises the pitch of a letter ; the flat lowers the pitch of
a letter. Therefore, to make a half-tone between F and G, the F
There are two forms of the Diatonic Scale. First, called the Major
Scale, has the sounds so arranged that there is a half-tone between the
third and fourth, and seventh and eighth. If the letter C is chosen as
the starting note of a scale (called the Keynote), we get a scale of
this kind without having to use a sharp or flat; therefore the scale of
C is called the Natural Major Scale.
If we take the sounds of the scale of C and rearrange them, begin-
ning with A as a keynote, we get the other form of diatonic scale
called the Natural Minor Scale.
The chief difference between a major and minor scale is, that in
the major there are two whole-tones from the keynote to the third
letter ; in the minor, a tone-and-a-half from the keynote to the third
letter.
As the scale of A minor is a rearrangement of the sounds of the
scale of C major, it is called the Relative Minor of C.
If a scale is begun on any other letter as a keynote, it is necessary
to use sharps or flats to make the whole and half-tones fall in the
proper places. When a piece of music is written in any of these
scales, the sharps or flats that the scale requires are put at the begin-
ning, and are called the Signature. Sharps and flats to the number
of six may be used in a signature. These signatures are here given :
must be raised or the G must be lowered, thus :

5. Key of Z>1?, or of its relative minor, B\> minor.
6. Key of Gb, or of its relative minor, F\> minor.
Observe that the sharps always begin with F§, and that they are al-
ways written in the order in which they are here set down. So also
with the flats, which always begin with B\> ; also, that F§ and G\} are
identical in pitch.
If the number of flats be increased to seven, the keynote would
be Cb, this being the same as F, which has five sharps. It is preferable
to write in F, it being easier to read in the key which has the fewer
modified letters. Keys with more than six sharps or flats often occur
in the course of a piece of music, but the sharps and flats are then
placed before the letters to which they belong.
When any sharp 01 flat, not found in the signature, occurs in the
course of a piece of music, it is called an Accidental.
Accidentals affect all the letters on the same degree on which they
are written, but their influence never extends beyond the measure in
which they occur, except when they occur at the end of a measure and
the same letter is repeated at the beginning of the next measure.
(This rule is very generally disregarded now, and the accidental is repeated.)
The Natural is never used in the signature, except when in the
course of a piece a change of signature occurs, when the old signa-
ture is canceled, thus :
When the natural
occurs in the course of a piece to cancel one of the sharps or flats in
the signature, it is an accidental. But when it occurs for the purpose
of restoring an altered note to its place in the scale, it is not an acci-
dental.
INTR OD UC TION.
xi
The natural cancels the double sharp and double flat also. Therefore,
if the double sharped letter is to be restored to its original place, the
natural and sharp are combined, thus, t$ ; if the letter is double flat,
thus, t[b. The following illustration gives examples of all the subjects
treated so far.
In piano music two staves are used, joined with a sign called a
Brace. Immediately after the brace the Clefs are placed ; then the
Signature, then the Time Signature. In the second measure the
natural is an accidental. A quarter and a half -rest are also found
in this measure. After the fourth measure the signature is changed —
also the time signature. Whenever either one of these is changed a
Double Bar must precede the change.
The clefs and signature must be put at the beginning of every line,
but not the time signature. Observe that in every measure the
united duration of the notes and rests equals the rhythmic unit indi-
cated by the Time signature.
In the eighth measure a whole-measure rest is indicated in the
lower part. A whole-rest is always used for this purpose, without
regard to what the time signature may be.
xii
INTR OD UC TION.
The duration of a note may be varied in another way; viz., by
tying it to another or to several more on the same degree. This sign
- — ^ is called a tie. The tie must be repeated for each note when
several are tied, thus : j 5 * ^ ^ j 5 * j* J
If the first note is marked with an accidental, it is not necessary
to repeat it as long as the tie lasts.
The duration of a note is also indefinitely extended by means of a
sign called a pause or fermata The pitch of the G clef is often
raised an octave by writing 8va over it. The octave higher
lasts until the dotted line ceases.
The pitch of the F clef may be lowered an octave by writing under
it 8vb Sva is an abbreviation of ottava alt a (octave
higher) ; 8vb is an abbreviation of ottava bassa (octave lower) .
The' Rate of Movement, called Tempo, is indicated by Italian
words, as, allegro, andante, etc. ;
The Intensity, by p, pft, ppp, which stand for piano (soft) , piu
piano (softer), pianissimo (softest), fiffifff, which stand for forte
(loud), piu forte (louder), fortissimo (loudest) ; sudden access of in-
tensity, by or a, ox fz\ gradual increase of intensity, -===; grad-
ual decrease, z==-. Many other words and signs are used, but they
may all be found in the Dictionary of Musical Terms.
Rules for writing the chromatic scale in any given key : In ascend-
ing, raise all the letters except the third and seventh.
In descending, lower all the letters except the first, fifth, and
fourth.
When any one of the major chords in the scale accompanies it,
think of it as a tonic chord and write accordingly.
Write in the same way, if the accompanying chord is its domi-
nant. The notes that must be changed in accordance with this rule
are marked x.

INTRODUCTION.
The advantages gained by this method of writing the chromatic
scale are two.
i st. It reduces the accidentals to the smallest number possible.
2d. It does not introduce an accidental that may not be found in
the dominant harmonies of the related group with one exception, viz.,
A$\ and even this is possible as the augmented fifth in the dominant
of G, and as the third in the supertonic harmony of its relative minor,
E.
DEFINITIONS.
Motion is similar when two parts or voices ascend or descend to-
gether ; oblique when one part is stationary while the other moves ;
co7ttrary, when the parts move in opposite directions.
A degree is from one letter to the next above or below, whether
distant a whole-tone or half-tone. Conjunct motion is motion by de-
grees ; disjunct motion is motion by leaps ; diatonic motion is from
one letter to the next; chromatic motion is from any letter to an
altered form of the same letter ; as, A-A\> or A-A\.
Enharmonic change is the substitution of one letter for another
without changing the pitch ; as, Cjf, D^.
HARMONY.
CHAPTER I.
Intervals.
Harmony treats of the combinations of sounds of different pitch,
and the successions of these combinations.
The basis of modern music is a series of sounds, each one of
which differs from the one lying next above or below by an interval
called a half-tone, semitone, half-step, or minor second.
If the two contiguous sounds are expressed by the same letter, as
C, Cjf. B,£b. it is called a Chromatic half-tone; if by different
letters it is called a Diatonic half-tone.
When the same sound is represented by different letters, as C$,
Z>b, it is called an Enharmonic change.
The difference in pitch between two sounds is called an Interval.
The number of letters included decides the name of the interval,
without regard" to the number of whole or half-tones it may include.
Thus, C-D$ is called a second because it includes two letters,
while C—E t>, which sounds the same ( in the modern scale ) , is
called a third because it includes three letters.
The names of the intervals within the limits of the octave are :
Second, Third, Fourth, Fifth, Sixth, Seventh, Octave.
But every interval may be written in several ways; as, C-T)\>,
C—D, C-D\. It is therefore necessary to distinguish between the
different kinds of interval bearing the same name.
This is done by the use of the following terms, added to the
name to denote the kind : Minor, or small ; Major, or large ; Per-
fect, Diminished, and Augmented.
Intervals are also classified as Consonant and Dissonant. A con-
sonant interval is one that gives repose to the ear. A dissonant in-
(i)
2
HARMONY.
terval is one of which it is necessary that one or both the sounds
must move in a certain way to satisfy the ear.
Consonant intervals are farther divided into Perfect and Imperfect.
A perfect consonance is one that cannot be altered without produc-
ing a dissonance. An imperfect consonance is one that is equally
consonant, whether major or minor.
A diminished interval results from the contraction of a minor or
perfect interval.
An augmented interval results from the expansion of a major or
perfect interval.
All aug.nented and diminished intervals are dissonant.
The motion of the member or members of a dissonant interval is
called their resolution.
If the dissonance is minor or major, only one member is compelled
to move ; if it is augmented or diminished, both members must move,
towards each other if the interval is diminished, away from each
other if it is augmented.
Although there are five kinds of interval, there are not five kinds
of every interval. Thus of seconds there are three kinds, viz. :
C-D\>, one half-tone, called minor second.
C-D, two half-tones, called major second.
C-Z>$, three half-tones, called augmented second.
It is quite possible to put a diminished second, or a doubly aug-
mented second on paper ; but as neither are to be found in any possi-
ble combination or succession, they are excluded as of no practical
use.
The third also exists in three forms, viz. :
Cj-jE'b, diminished, two half-tones.
C—Jlb, minor, three half-tones.
C-E, major, four half-tones.
The fourth exists in three forms, viz. :
C\-F, diminished, four half-tones.
C-F, perfect, five half-tones.
C-jFJ}, augmented, six half-tones.
The remaining intervals within the limits of the octave may be
found by'inverting the letters of those just given. It will at once be
evident that any interval and its inversion must together make an oc-
HARMONY. 3
2d. 7th.
tave, thus, C D C; and since twelve half-tones make an octave,
an interval and its inversion must make twelve half-tones. There-
fore, to find the number of half-tones in the inversion of a given in-
terval, it is necessary only to subtract the number in the interval from
twelve, the number in the octave ; thus, in the second C-D there are two
half-tones, therefore there must be ten in its inversion, D-C\ and as the
number of letters from D to C is seven, we also find that the inversion
of a second produces a seventh. Then the inversion of a third must
produce a sixth, and the inversion of a fourth must produce a fifth.
Then, as there are three kinds of each interval, three kinds of
sevenths, sixths, and fifths must result from their inversion ; and the
nearer each other the sounds are in the smaller interval, the farther
apart they must be in its inversion. Therefore the inversion of a
given interval always produces one of the opposite kind, with one ex-
ception; viz., the inversion of a perfect interval produces a fieifect
one.
The foregoing explanations will make the following table of inter-
vals clear. (See page 5.)
Intervals may also be divided into diatonic and chromatic. Dia-
tonic are to be found in the major scale and in the natural minor
scale ; chromatic result from the introduction of sound's foreign to
the scale.

NOTES.
( i.) These questions must be asked over and over, and the various intervals must be written,
until the whole chapter is understood and committed to memory.
( 2.) The half-tone is used as a measure for the intervals, it being more convenient than it
would be to use both whole and half-tones.
(3.) Whole-tone and half-tone are used in preference to the German whole-step and half-step,
their meaning being perfectly clear ever since they were first used in English.
(4.) Dissonant intervals are by many writers called discords. A dissonant is pleasant; a
discord is something that never should appear in music.
( 5.) The perfect fourth and fifth are by some writers called major. The diminished fifth is
also called imperfect. The augmented sixth is called extreme, or extreme sharp sixth. The
names adopted in this work seem more logical and less likely to contuse the student.

These groups are called TetrachordS (from two Greek words meaning four
strings) .
A major scale may therefore be defined as being formed of two
Tetrachords separated by a whole-tone.
As the Tetrachord must consist of a succession of two whole-tones
followed by a half-tone, if it begins on any letter but C or G it is
necessary to alter the pitch of one or more of the letters to make it
conform to this succession. It is for this purpose that sharps, flats,
double sharps, and double flats are used. For example, if it be desired
to write a Tetrachord beginning on A, the succession of letters will
be A, B, C, D; but as the interval between B and C is a half-tone,
and that between C and D a whole -tone, it is necessary to move the
C closer to the D ; therefore it is written A, B, C§ D.
If a Tetrachord is to be written beginning on B, the letters will be
HARMONY.
7
F, G, A, B ; but as j5 is a whole-tone above A its pitch must be
lowered by making it flat; thus, F, G, A, 2>b.
By examining the following series of sounds it will be found that
the Tetrachord that makes the second half of the scale of C is also
the first half of the scale of G, and the Tetrachord that makes the
first half of the scale of C is also the second half of the scale of F.

Therefore, Every Tetrachord belongs to Two Scales, that of the letter
it begins with and that of the letter it ends with. These two scales
are called related scales.
Therefore every major scale has two related major scales, one be-
ginning on the last note of the first Tetrachord, the other on the first
note of the second Tetrachord. (The easiest way to remember is, the related major
scales begin on the fourth and fifth of the given scale.)
Every Tetrachord must contain four successive letters, and every
scale must contain all seven letters and the octave of the letter it begins
with.
It is this that necessitates the use of double sharps and double flats.
Thus, if a Tetrachord is to begin on D§, the letters will be F, F,
G ; but to make a Tetrachord they must be, F3i~ lp— j^ = t^ = t ==: | : |
Or, if the Tetrachord begins on F\>, the letters will be F\>, G, A,
B\ but they must be written.

CHAPTER III.
Major Scale Continued, and Common Chord.
The following names are given to the degrees of the diatonic scale :
First, or keynote, is called the Tonic ;
Second, SllpertOniC (upon or over the tonic) J
Third, Mediant;
Fourth, Subdominant ;
Fifth, Dominant ;
Sixth, Submediant;
Seventh, Leading Note.
Mediant (from Latin medius= middle) is so called because it is half-way
between the tonic and the fifth above, or dominant.
Subdominant (Latin sub = under) is so called because it is the same
distance below the Tonic (a fifth) that the Dominant is above.
Dominant (Latin dominans = ruling) is so called because its harmonies
rule or determine the Scale. (Originally the dominant was so called in the eccle-
siastical system because it was the principal reciting note of the chant.)
Submediant is so called because it is half-way between the tonic
and the subdominant.
Leading Note is so called on account of its tendency to ascend to
the keynote. (This note is also called the subtonic, in Latin nota sensibihs, in French note
sensible = sensitive note, on account of this tendency.)
COMMON CHORD, OR PERFECT CHORD OR TRIAD.
A Common Chord consists of three sounds. The sound on which
the chord is built is called the Root ; the next is the Third above the
root; the next is the Fifth above the root.
The third over the root may be major or minor : if major, the chord
is called a Major Chord; if minor, the chord is called a Minor Chord.
The fifth over the root must be perfect ; if it is not, the chord is not
a common or perfect chord.
HARMONY.
As there are only seven letters used in music, it follows that seven
groups of letters must make all the common chords possible, as each
letter may be the root, or the third, or the fifth of some chord, thus:
Fifths, E, E, G, A, B, C, D.
Thirds, C, D, E, E, G, A, B.
Roots, d, £, C, Z>, E, E, G.
It will be seen that to form a chord on any given letter, for exam-
ple, A, it is only necessary to skip one letter to find the third, C, then
skip another letter to find the fifth, E ; thus, A (B) C(D)E. There-
^ ' s s
fore, there is an interval of a third between the root and third, and
an interval of a third between the third and fifth. If from I to 3
is a major third, from 3 to 5 is a minor third ; if from 1 to 3 is a minor
third, from 3 to 5 is a major third ; if from 1 to 3 and 3 to 5 are both
minor thirds, the chord is called a Diminished Chord (or imperfect ) ; if
from 1 to 3 and 3 to 5 are both major thirds, the chord is called
an Augmented Chord ( neither are common chords) .
In every major scale Six common chords may be written, (i.e. with-
out using any accidentals) . Three of these chords are major, three minor.
The chords take the names of the degrees of the scale upon which
they are written ; therefore the chord on the
First is called the Tonic Chord, and is Major ;
Second is called Supertonic Chord, and is Minor ;
Third is called Mediant Chord, and is Minor ;
Fourth is called Subdominant Chord, and is Major ;
Fifth is called Dominant Chord, and is Major ;
Sixth is called Submediant Chord, and is Minor.
The seventh or leading note may not be used as a root, because the
fifth over it is diminished. (Diminished and augmented chords will
be treated of in the proper place.)

the chord. Thus the following example contains the chord of A

Therefore, to rind the root of a chord arrange the letters composing
it to read (upwards) One, three, five. (This rule should be borne in mind; it
will be extended farther on.)
The pupil should be required to write major and minor chords, using- every natural, sharp, and
fiat as roots. The following remarks will aid in remembering the perfect fifths.
I. Every fifth that may be struck on two white keys is perfect,
except B-F; to make a perfect fifth between these letters, either B
must be flat or F sharp.
II. Every fifth that may be struck on two black keys is perfect.
III. There are only two perfect fifths that have the root a white
and the fifth a black key, viz., B-F§ and Cb- G\> ; only two that
have the root a black and the fifth a white key, viz., Bb-F and A\-
Write the following chords in their natural positions, that is, root,
third, fifth, and mark every chord major or minor, as the case may
be.

CHAPTER IV.
Position and Succession of Common Chords.
The lowest note of any group sounded together is the Bass.
(This word should be spelled base, because the proper meaning of bass is a deep sound.)
It is not at all necessary that the bass note of a group be written
on the "bass" staff.
Avoid any confusing of Bass with Root. The root may be the
bass, but the bass may be any member of the chord. The first step
in learning to use chords is to learn how to write successions in
which the Roots are always the Bass Notes.
The most effective harmony is that written in four parts (or for
four "voices"). Since the common chord has only three letters in
it, it is necessary to repeat one of the letters to make a fourth part.
When the root is used as a bass, the root itself is the best member to
repeat ; thus, C, E, C7, C. It will be evident that while retaining
the root C as a bass, it is possible to make three different arrange-
ments of the remaining letters. Thus, instead of having the repeated
root at the top, the third, E, might be, or the fifth, C7, might be.
Therefore we have this rule :
Every chord with its Root at the Bass, and with the Root repeated,
may be written in Three Positions.
If the repeated root is at the top,
it is called the Octave Position (1) ;
if the third of the chord is at the top,
it is called the Tierce Position (2) ;
if the fifth is at the top, it is called
the Quint Position (3).
For the present these positions are indicated by placing over the
top of the group, 8 for octave, 3 for tierce, and 5 for quint position.
(Pupils should be required to do this until they are quite familiar with the positions.)
HARMONY.
It is necessary to remember that the term Position always means
that the Root is at the bass. The first and most important rule to be
observed when writing a succession of chords in Positions is — Two
Chords must never occur in Succession in the Same Position.

c. First chord, fifth position; the next may be third or octave.
d. Both chords in octave position forbidden.
e. Both chords in third position forbidden.
f. Both chords in fifth position forbidden.
Consequently there is always a choice of two positions; viz., either
of those in which the last chord is not written.
In general a better effect is produced when the three upper parts
move in the opposite direction to the bass, especially when the bass
moves only one degree. (More exact rules for this will be given
later.)

The motion from first to second chord is called oblique — that means
one part (the top) is statioiiary, the bass moves. 2 to 3 is contrary
motion; the bass (a) moves one degree. 3 to 4 is direct or parallel
motion ; bass and top both ascend. At b the bass moves one degree.

CHAPTER V.
Sequences of Common Chords.
The movement of common chords is absolutely free; that is, any
chord in the scale may be followed by any other one. Some of
these successions will be found to be much smoother than others,
but there is no succession that cannot be made to sound well when
used in the right place. For example, the following passage
— 1:| may be harmonized in the following ways :
1 is smooth but commonplace.
2 is more vigorous.
3 is rugged almost to harshness.
4 is dignified, with a savor of quaintness.
In 2 the progression from first to second chord, (i. e., from a major
chord to the minor chord on the third above,) was not considered good at one time.
In 3 the progression from first to second chord, (i. e., from a minor
chord to another minor chord one degree above or below,) was forbidden. The pro-
gression from the second to the third chord, (i. e., from a minor chord to the
major chord a third higher,) was not considered good.
No rule can be given as to when one of these harsh progressions
will sound well and when it will not. The judgment of the composer
as to the effect he wishes to produce is the only guide ; but pupils should
avoid this class of successions until they have thoroughly learned all
those that are smooth and natural.
HARMONY.
There is one other progression that should be avoided; viz., from
the subdominant to the dominant, except the subdominant is in the
eighth and the dominant in the fifth or third position, thus:
5 3
N. B. The above remarks must be
understood as applying only to Suc-
cessions of chords in Positions ; i. e.,
with their roots at the bass.
Common chords are frequently written in what are called Sequen-
ces (Latin sequens= following). In a sequence the roots move in a regular
order or pattern, for example :
-a —
P
up four, down three. The result is three pairs of chords, each one
degree higher than the last.
The most usual sequences are here given, both ascending and de-
scending. The pupil should write them in various keys and should
also exercise his ingenuity in constructing others.
a, 6, c, are ascending sequences.
d, e, f, are descending sequences.
i.S
HARMONY.
It is allowable to use the dimin-
ished (leading note) chord in a
sequence for the sake of preserving
the "pattern," thus:
The use of the diminished chord
was sometimes "dodged" by the
older writers in the following way :
The jE>Q is retained in the chord
of G because B\ would necessitate
a chromatic progression, B\>, 2?tj,
which was forbidden in strict coun-
terpoint.
Sequences composed of common chords natural to the scale are
called Diatonic or Contrapuntal. They were much more largely
used by the old school than by the new ; still it is absolutely necessary
that the pupil should familiarize himself with them. The reason why
will appear farther on.
The Positions of the chords may be changed in all these examples;
thus, Example a, page 17, may be jive, three, or three, eight, or
three, Jive, or eight, three, alternately, thus:
5353 3838 3535 8 38 3
This is not as
good as the others.
Observe that the best effect is produced when the outer parts move
in opposite directions.
It does not sound well to move to a chord in the Octave Position
with the Bass and upper part (soprano) moving in the same direction,
except in the following cases:
I. From Dominant to Tonic Chord.
II. From Tonic to Subdominant chord. (The relation between these chords
is the same as that of the previous chords.)
HARMONY.
l 9
g2.

Another rule is often given, viz., that the eighth may occur in
Direct Motion when the upper part ascends a half-tone ; but whenever
this is the case, it must be either a progression from Dominant third
position to Tonic octave, or Tonic third position to Subdominant octave.
N. B. It is owing to the infraction of this rule that this passage does
not sound well. Another progression that does not sound well is
that to a Chord in the Quint Position with the outer parts (bass and
soprano) moving in the same direction, except in the following case:
From any chord to another, the roots of which chords are a fifth
apart (ascending), or what is the same, a fourth apart (descending).

CHAPTER VI.
First Inversion of Common Chords.
If the preceding chapters have been thoroughly mastered, the pupil
will know all that may be done with the Common Chords natural to
the Scale, with their Roots as Bass notes; i. e., in Positions.
The next step is to Invert the chords. Inversion means using some
other member of the chord as a bass.
If the Third of the chord is used as a bass, the Chord is said to be
in its First Inversion.
The First Inversion of a Chord is subject to no restrictions; that
is, any chord in the scale may be written with its third at the bass.
When the Third is used as a bass, the Root or Fifth may be re-
peated (to make the fourth part) ; it is immaterial which.
b.
d.
a. Chord C, E, G, with the third,
E, at the bass, the root repeated.
b. Same, with the root repeated
at unison. This is signified by
doubling the note.
c. Same, with the fifth repeated.
• d. Same, with fifth repeated -at unison.
It is a rule that No two Voices or Parts must ever move together
in Fifths Or Octaves (making what are called parallel or consecutive fifths or octaves).
(This rule will be largely modified in the proper place, but must be strictly observed at present. )
It is in consequence of this rule that it is forbidden to write two
chords in succession in the same position.
a. Both in octave position;
therefore the Jirst and fourth
parts move together in octaves,
the second and fourth in fifths.
b. Both in third position;
second and fourth in octaves,
third and fourth in fifths.
HARMONY.
c. Both in fifth position, first and fourth in fifths, third and
fourth in octaves.
The doubling of the third, when two chords are written in suc-
cession in the tierce position, is sure to avoid the parallel fifths and
octaves.
In writing the same Position twice in succession, the parallel fifths
or octaves will always be found between the bass and one of the
upper parts. If two First Inversions are written in succession, the
parallel fifths and octaves will occur between two of the upper parts,
thus :
a. Octaves between first and
third parts, fifths between second
and third, caused by repeating the
root in both chords.
b. Octaves between first and
third parts, fifths between first and
second, caused by repeating the
fifth in both chords.
Therefore they may be avoided by repeating the Root in one
chord and the fifth in the other, or repeating one at unison, the
other at the octave.
a. Both roots repeated — one at unison, the other at octave.
b. Fifth at unison, root at octave.
c. Root at octave, fifth at octave ; but the repetition of the root
makes an octave between the frst and third parts, that of the fifth
an octave between the second and third parts, and to be parallel,
they must occur between the same two parts.
d. Both fifths repeated. The first and second parts being in
unison, there is a fifth between them and the third part; but the
second fifth is between the first and second parts. - . ..
HARMONY.
e. The repeated C is root of one and fifth of the other chord ; but
these octaves are not consecutive because they are stationary. To be
consecutive they must move.
f and g. Roots repeated, unison and octave.
Parallel fifths and octaves may also be avoided by repeating the
Third of one or both of the inverted chords, provided the repetition
of the Third is made by two parts moving in opposite directions.
The Third of a chord may be repeated at any time, if the repeti-
tion occurs in parts moving in opposite directions.

a. First and second chord

peated.
b. Second chord only invert-

c. Third of second chord repeated.
d. Same.
e. The third of the same chord repeated. This case is peculiar as
it really makes parallel octaves between the first and fourth parts, but
they occur in opposite ( contrary ) motion. The long skip of the
bass also helps to hide them.
f. The third repeated in both chords.
The above examples should be written in all the keys, until they
are thoroughly understood and memorized. Then the exercises fol-
lowing should be written, care being taken to introduce examples of
all the progressions here given.
Any bass note may be treated as a Root, or as a Third.* When it is
treated as a third, put a 3 under it, and no figure over the upper part.
* Note. It is perhaps necessary to repeat that the leading note cannot be a root; therefoie
the second of the scale cannot be a third.

CHAPTER VII.
Second Inversion of Common Chords.
When a chord is written with its Fifth as a bass note, it is called
the Second Inversion of the Chord.
The use of Second Inversions is very much restricted.
A Chord in its Second Inversion is either a Tonic, a Subdominant,
or a Dominant.
The Second Inversion of a Tonic may be used at any time, pro-
vided it is followed by the Dominant Chord. (Note the author is well aware
of the rule which says, it must never enter with a leap in the bass, but fails to see the utility of
rules that the greatest composers disregard.)
In Second Inversions, the fifth (bass note) is the best to re-
peat.
a. Second inversion of tonic, preceded by tonic, b. By supertonic.
c. By mediant, d. By subdominant. e. By submediant. f. By first
inversion of supertonic with third doubled. This succession and that
at d are very smooth and orthodox.
Cadence (Latin cado= to fall). This term is applied' to various kinds of
endings. The Perfect or Authentic Cadence is the final tonic pre-
ceded by the dominant with its root at the bass. This is emphasized
if the dominant is preceded by the second inversion of the tonic, and
still more emphasized if the second inversion of the tonic is preceded
by the subdominant (as at d) or supertonic (as at /) .

The Second Inversion of the Dominant chord is preceded by the
Tonic Chord with its root at the bass, and followed by the Tonic Chord
with its third at the bass, or just the reverse. This second inversion
is not often used on the accent of the measure. It is apt, in this case,
to sound like a Tonic chord.
x x x x
a and b are better than c and d, on account of the contrary motion
between the outer parts.
Although the second inversions always enter as above, viz., if a
tonic, after any chord in the scale; if a subdominant, after the tonic,
root at bass ; if a dominant, after the tonic, root or third at bass —
they do not always conform to these examples as to the chord that fol-
lows them ; but the rest of this subject must be reserved for a later
chapter.

CHAPTER VIII.
Harmonizing of Melodies, with Common Chords and
Their Inversions.
The knowledge of Common Chords now gained, must now be ap-
plied to the harmonizing of Melodies ; first, with the Chords in Posi-
tions.
As every chord may be written in three positions, it follows that
every note in a melody may be either the root, third, or fifth of some
chord belonging to the scale. If it is treated as a root, the bass will
be the same letter ; if as a third, the bass will be the third letter be-
low ; if as a fifth, the bass will be the fifth letter below.
It is evident that if two notes in succession in the melody are
treated as roots, or thirds, or fifths, the result will be two chords in
the same Position.
Begin and end with the Tonic Chord. Observe that the melody
may begin on the root, third, or fifth of the tonic. Be careful to
avoid using the Leading note as a root.
The first time the exercises are written, observe carefully the rule,
not to write two successive Positions alike.
The second time they are written, find as many opportunities as
possible to put two or three successive chords in the Tierce Position.
Sequences are indicated in the Melody as they are in the bass, by
the notes moving in a regular pattern. Thus, the following notes
hEEjzzfj indicate the following Sequence:
Others may readily be found

Two are minor, viz., Tonic and Subdominant; two major, viz., the
Dominant and Chord on sixth.
Dominant chords must be major. This is the harmonic reason for
the raising of the seventh; hence this scale is called the Harmonic.
Note. In the older writers the raised sixth was harmonized as the fifth or third of a chord. It
is rarely found in modern music. Another form of minor scale was also used by the older writers,
called the mixed minor. In this scale the 6 and 7 were raised both ascending and descending.
Consequently it differs from the major scale only in having the third above the tonic minor. This
scale will be found frequently in Bach and Handel.

A Major Scale and its Relative Minor are so closely bound together
that they may conveniently be looked upon as one and the same thing.
Consequently if the seventh of the minor scale appears not raised, it
is generally as a member of one of the chords in the related major
scale.

It was customary at one time to end all compositions in the minor
key with a major tonic. This major third was called the "Tierce de
Picardie." It is still occasionally used.
In harmonizing the exercises that follow, find opportunities for the
use of the relative major chords. The natural seventh of the minor
scale must (at present) be either root or fifth of a chord in the relative
major.
It is necessary now to speak of the Diminished Chord, but more
will be said about it later.
Diminished Chords may be used freely, with the proviso that they
are used in the first inversion.
In the Major scale there is but one ; viz., on the Leading note. In
the Minor scale in addition to one on the Leading note there is one
on the second (Supertonic) of the scale. This last mentioned chord is
very important in the minor scale.
The Bass note of this chord is the
best to repeat.

' ' CHAPTER X.
The Group or Circle of Related Keys.
In Chapter II. the relationship of Major scales through the Tetra-
chords is explained. In the last chapter the relation between a
Major and its Relative minor is explained. This relationship must
now be extended to include the Relative Minors of the Major
Relations.
Thus, given the key of C, the related majors are E, G.
The relative minors A, D, E.
Thus a given key always includes a group of six keys, three Major
keys and their Relative Minors.
Each of these scales must have a leading note ; thus, C being the
key, E, its first major relative has E as leading note. G, the sec-
ond major relative, has E§ as leading note; A minor has G§; D
minor, Cjf ; E minor, Z$.
So four accidentals may be introduced in the scale of C, as lead-
ing notes to the related scales. We found that the leading note of
the minor scale was only to be found in the dominant chord, in
which chord it is the third. From these facts we deduce the follow-
ing rule :
Notes raised by accidentals are Leading notes to Related Keys,
and they are always harmonized as Third in the Dominant Chord of
the key to which they lead.
The most natural progression of a Dominant chord is to its Tonic.

6. Dominant and tonic of Key.
It is much to be regretted that one word, modulation, is used to
signify going into a related key transiently (especially by means of its domi-
nant chord), and going outside of the related groups.
The writer has thought that for clearness' sake, the word modu-
lation might be used only in the first sense, and that the word
transition better describes this passing to a new group of relations.
Therefore in this work these words will be used with this distinction
between them.
In all the modulations in the foregoing example, the idea of the
original key is never lost for a moment, — what is called the "Tonality."
The reason, perhaps, is that the Tonic chords are simply the six
common chords of the original scale. If one of these Tonics, when
preceded by its dominant is changed, for example, if the tonic of
D minor ( 1 ) is changed to major, the tonality of the original key
is at once lost, and a transition is made.
The following examples will show how these dominant chords may
be used.

Chords of Parallel Minor, Lowered Supertonic, and

In addition to the Dominant chords of the Related keys there still
remain some Common chords which may be used without making a
transition.
Taking C as our given key, the related key of F possesses two
chords, C7, Z?b, D and D, F, that are not found in C. The
related key of G possesses one that is not found in C, — F, D, F$.

Observe that the third and seventh are the only notes in the scale
which may not be sevenths.
The Bb, needed to make the seventh in the dominant of F, makes
the fourth chromatically lowered note — (the others being, two belonging to
the parallel minor, and the lowered supertonic) .
For the present the lowered leading note of the scale must be har-
monized as a dominant seventh.

follow.

Dominant Seventh, Second and Third Progressions,
and Succession.
A dominant seventh chord may be repeated indefinitely, with
changes in its position and inversion, provided that the dissonance
is resolved when the Progression

takes place. In the following
example, the Dominant chord
is struck four times before the
progression to the Tonic takes
place.
The Second Progression of the dominant seventh is to the Sub-
mediant (sixth of scale) .
This progression only takes place with the Root of the Dominant
at the bass.
The Seventh and fifth descend. (The fifth must descend, otherwise it would
make parallel fifths with the root.)
The Third ascends except when the fifth of the dominant is at
the top. When this is the case it may descend.
The Root ascends to the root of the submediant.

This progression may take place with any inversion.
The seventh descends; the fifth and third, being common to both
chords, either remain stationary, or they may change places ; that is,
while cne voice moves from the third to the fifth, another may reverse
this, moving from the fifth to the third.
The Root ascends chromatically.
The seventh of the first chord may skip to the seventh of the
second, while the fifth ascends to the Root ; or the seventh may skip
to the fifth of the second chord ; last, the seventh may be omitted
from the second chord.

It is necessary to observe that this progression may only be used
with melodic passages that will permit of the resolution of the
second chord as indicated by the small notes.
In addition to the Three Progressions of the dominant seventh
chord, it is possible to make a Succession of dominant seventh chords,
as follows :
The third of the chord, instead of being made to ascend, is lowered
chromatically, and is made the seventh in the succeeding chord.
This Succession has the root and fifth, or third and seventh alter-
nately at the bass ; or all the chords may have the roots at the bass
by omitting the fifth from every alternate chord.

Dominant Ninth.
The next addition to the dominant chord is the Ninth over its root.
The ninth may be either Major or Minor.
Major ninth contains an octave and a whole-tone.
Minor ninth, an octave and a half-tone.
In Major keys both kinds of ninths are used.
In Minor keys the minor ninth only may be used.
The ninth resolves by descending one degree.
The ninth may not be used as a bass.
The ninth may not be written close to, or below the root; hence
three inversions only may be made of this chord.
'The fifth must ascend when below the ninth.
In four-part harmony, the third, fifth, or seventh may be omitted.
The first progression only is possible when the ninth is added.
The Succession of dominant chords may be made, provided the
ninth is used only with alternate chords.
In general, the minor ninth sounds better than the Major when it
}t at the top of the chord,

14. Succession of dominants. The ninth is not added to the sec-
ond chord, but is to the third. If the succession were continued the
fourth chord would be without the ninth. This example should be
written in several keys.
We found ( page 56 ) that it is possible to change the arrangement
of a chord at will, and that there was no Progression until the har-
mony changed; but as the ninth in descending moves to the root of
the chord, there may be Resolution without Progression, thus :
The ninth and seventh may also move
freely to any other member of the chord be-
fore progression takes place.
1. Ninth leaps to seventh, then seventh to fifth.
2. Ninth ascends to third.
3. Ninth leaps up to seventh.
4. Seventh leaps up to ninth.
This shows that resolution, although it may ( in the case of the
ninth ) take place without progression, is not compulsory.
62
HARMONY.
The chord of the ninth is much used with the Root omitted. The
remaining notes may be inverted in any form, and may have the first
and third Progressions.
The omission of the root from a chord with Minor ninth makes
it what is known as the Diminished Seventh Chord.
The fifth may descend in the diminished seventh chord when it is
below the ninth, if the ninth is not at the top.

1. Third, fifth, seventh, major ninth, first progression.
2. Third, fifth, seventh, major ninth, third progression.
3. Third, fifth, seventh, minor ninth, called diminished seventh
chord, because the interval from third to minor ninth is a diminished
seventh.
4. Diminished seventh from dominant of C, and diminished seventh
from dominant of A, its relative minor. Observe that three of the
letters are common to both chords, and that the remaining sounds are
enharmonically identical. It is owing to the fact of these two chords
(viz., the dominant of any key, and the dominant of its relative minor) having SO many
sounds in common, that it is so easy to pass from one to the
other.
5. Z>, the fifth, is at the bass and descends because ^4t>, the ninth,
is not at the top.
Some more examples of the third progression.

these cases the notes that are common to both chords may change
places in a variety of ways.

It would be time well spent to write out a number of tables like the
preceding, taking care to get in the accidentals correctly.
Observe, that the seventh in the dominant of a major key is the
ninth in the dominant of its relative minor; therefore all the notes in
the scale that may be sevenths (Chapter XII.) may also be ninths on
the same conditions.

The succession of dominants may be made with diminished seventh
chords. Mistakes are often made in writing this succession ; but by
applying the simple rule that the lowered third becomes the seventh
in the next chord, and remembering the roots of these chords are
the dominants of the related group, no mistake need occur. Observe
that after writing six, all the dominant chords in the group, if you
wish to continue the passage, return to the first chord — it being enhar-
monically the same as A, C, E\>, Gl?, the chord that would follow
jB\), D\>, G, according to the rule. In other words, when the
lowering of the third will give a chord, the seventh of which is outside
of the related group, substitute the diminished seventh chord belong-
ing to the key of the mediant.

In all these examples, A, the ninth, may be ^4b, because the ninth
may be major or minor in major keys.

Third Progression. (To dominant of relative minor.) Owing to
the number of sounds common to these two chords (Chapter XIV.),
this progression takes several forms ; any of the notes may be at the
bass.
II
1. Fifth at bass, ascends to root of dominant relative minor; elev-
enth, ninth, and seventh descend.
2. Fifth at bass, stationary; eleventh, ninth, seventh descend.
3. Fifth at bass; seventh and fifth stationary ; eleventh and ninth
descend.
4. Fifth at bass; ninth, seventh, fifth stationary; eleventh de-
scends ; result is that both are eleventh chords.
*This chord may have the same root as the preceding, in which case it
would be third to ninth.
Write this progression out with every possible arrangement of the
notes ; also the first and second progressions with different arrange-
ments of the upper notes.
The eleventh and ninth may descend while the seventh and fifth re-
main (as if the root were present), or the fifth may ascend to the
root. In this last case, if the fifth is at the bass and ascends to the
root of the dominant, the eleventh and ninth may ascend.
N. B. The descent of a fifth is always the same as the ascent of
a fourth.

Broken into five groups of four

First group, counting from lowest note, consists of major third,
perfect fifth, minor seventh ; is therefore Root to Seventh.
Second group (counting as before) consists of minor third, dimin-
ished fifth, minor seventh ; is therefore Third to Major Ninth.
Third group consists of minor third, diminished fifth, diminished
seventh ; is therefore Third to Minor Ninth.
Fourth group : minor third, perfect fifth, minor seventh ; is there-
fore Fifth to Eleventh, with major ninth.
• Fifth group is like 2 ; therefore a group consisting of minor third,
diminished fifth, and minor seventh, may be either Third to Major
Ninth, or Fifth to Eleventh, with minor ninth. To decide which it
is, it is only necessary to remember what the roots of the dominant
chords of the Related group are. Therefore Z>, F, A\>, C, if found
in the key of C, must be fifth to eleventh, with minor ninth, because
if it were third to major ninth, it is evident that Ffo would be the
root.
As to the other group, B, D, F, A, it may be third to ninth,
dominant of C, or fifth to eleventh in the dominant of the relative
minor of C.
Arrange the following groups in thirds, and find the roots. State

Additional Remarks on Second Inversions.
The second inversion of a chord may be followed by any chord
with the same bass as that of the second inversion, or with a bass one
degree above or below that of the second inversion. The second in-
version of the tonic may be followed by the first inversion of the tonic.

4. The chord of ^4 minor, second inversion, enters as a tonic;
but as it bears the relation of mediant to the key of F, advantage is
taken of the fact that a second inversion may be followed by any
chord with the same bass, and the dominant of F follows it.
5. Second inversion of tonic, changed to a dominant by the addi-
tion of the seventh to which the fifth skips.

CHAPTER XVII.
The Progressions of the dominant so far given, are the most natu-
ral and most usual ; but successions may be made of which no satis-
factory explanation can be given, in accordance with the following
rule :
Any two of the Dominant Harmonies of the Related Group may
be written in succession (with a few exceptions) , provided they have at
least one sound in common.
The dissonant notes are not always resolved in these successions,
nor are these successions agreeable, except in certain arrangements
of the chords.
The first thing to be done, is to find in which dominant harmonies
each note in the scale may be found as root, third, fifth, seventh,
ninth, or eleventh.

The chords marked x cannot be written in succession, although they
have a connecting sound.
We give some examples below of these successions, in the arrange-
ments which are most effective. The pupil should try other arrange-
ments and should write them in various keys. No other exercise can
equal this in giving the student a sure grasp of the possibilities of
chord successions without transition.
The successions that come under rules already given are omitted ;
viz., the third progression (page 57), and the succession by lower-
ing the third (page 58.)

These examples, with two exceptions, only give the movements
from the first -chord to the others containing the same connecting
note ; but the movement may take place from any chord of the group
to any other, with scarcely an exception. All the successions given
may be reversed.
The two chords marked N. B. in the first example are identical in
sound, because the diminished seventh derived from the dominant
of a major key, and that derived from the dominant of its relative
minor, are enharmonically the same, thus :
B, D, F, ufi^G% B, D, F
Dominant of C, dominant of A minor.
B, G, B\>, J3vTc% B, G, B\>.
Dominant of F, dominant of D minor.
F% A, C, B^B^ Fl A, C,
Dominant of G, dominant of B minor.
The minor ninth in the dominant of the major is enharmonically the
third in the dominant of its relative minor.
Observe in all these successions that the connecting' note must re-
main in the same part.
The following successions in which there is no connecting note

Chord of Thirteenth.
In the majority of cases the thirteenth may, for practical purposes,
be treated as a changing note, or as a retardation. Still there are
some cases in which its movement is such that it must be looked upon
as an essential dissonance.
The thirteenth, like the ninth, may be major or minor. The fifth
is generally omitted when the thirteenth is added, especially in those
cases in which the thirteenth descends to the twelfth (i. e., the fifth
of the chord).

12. First chord, dominant, root, third, seventh, ninth; second
chord, dominant, root and ninth having changed places; viz., bass,
ninth; tenor, eleventh; alto, thirteenth; soprano, root. This passage
is the only one in which the root may be struck over the ninth with
good effect, owing possibly to the fact that the whole bar consists of
dominant harmony, and also to the diatonic contrary motion.
In analyzing harmony a good rule to follow is, take the most obvious
explanation, especially when the combinations may be ''parsed" as
common chords, instead of hunting for hidden "roots." For exam-
ple, the following passage from Tannhauser is thus explained by one
author. The note marked x is enharmonically B\>, consequently is
the ninth, C$ the third, and F\ the thirteenth in the dominant of D.
But if it is looked on simply as the second inversion of JF$ major,
changed to F\ minor, and followed by the chord on the sixth ( D
major), a much simpler explanation maybe given; viz., B minor,
the preceding chord, is the minor subdominant of F$, which enters
as a tonic; second inversion is changed to minor, and followed by
the chord on the sixth.
The beauty of the passage is owing largely to the uncertainty of
key and the kaleidoscopic rapidity with which the changes of key
take' place.
The following passage, also by Wagner, the same author, calls
an unusual form of augmented sixth, calling the Lfo a miswriting
for Cj}, in spite of the fact that the C is natural when the harmony
changes.
S6
HARMONY.
It is much easier to say it is the diminished seventh chord, dom-
inant harmony of Bfo. The Lfo is a changing note which leaps to
another member of the chord, then runs to its resolution, C. The
chord A\, C, E\>, Gb, is enharmonically A, C, E^, a derivative
of the chord that follows. It follows that in both instances Wagner
wrote his chords properly.

CHAPTER XIX.
Supertonic Harmony.
There is another progression of dissonant groups, that differs so
widely from any that they have as Dominant harmonies, that to dis-
tinguish them they are called Supertonic Harmonies, from the fact
that their progression is to the Tonic chords of the keys in which their
Roots are the Supertonics.
The major ninth is stationary. The minor ninth ascends chromat-
ically in Major keys, is stationary in minor keys. ( The major ninth cannot
be used in minor keys. )
The seventh is stationary.
The fifth and third go to the fifth of the Tonic.
The root when at the bass goes to the fifth of the Tonic ; when not at
the Bass, to the third of the Tonic generally, but it may go to the fifth.
1. Supertonic harmony
of C, with major ninth
stationary.
2. Supertonic harmony
of C, with minor ninth
ascending chromatically.
3. Supertonic harmony of A minor, with minor ninth stationary.
As the root, third, and fifth all go to the fifth of the tonic, it will at
once be seen that the second inversion of the tonic generally follows.

CHAPTER XX.
Altered Chords, Augmented Sixth, Augmented Fifth,
Passing Seventh.
There are a few chords that are produced by altering one of the
members of a given chord, chromatically.
Strictly considered, this altered note is nothing but a passing note
between the member of the chord and the note to which this mem-
ber moves.
The most important of these chords by alteration is called the Aug-
mented Sixth Chord.
This Chord results from the chromatic lowering of the fifth of a
dominant or supertonic harmony, root to seventh or third to minor
ninth.
The progression of the chord is unchanged. It maybe inverted in
any Way, but the chromatically lowered fifth is generally used as a
bass.
The chord gets its name from the fact that the interval between
the lowered fifth and the third of the chord is an Augmented Sixth ;
thus, D, Ah, F%
Root, Fifth, Third.
1. Progressing like a dominant, root present.
2. Progressing like a supertonic harmony, root present.
3 and 4. Same as 1 and 2, but the root is omitted and minor
ninth added.
5 and 6. Progressing like a dominant to a minor tonic. This pro-
9 2
HARMONY,
gression of the augmented sixth is unusual. When it progresses like
a dominant, the chord to which it moves is (generally) also a
dominant.
The parallel fifths that occur in 3 and 6 are not at all unpleasant.
They may be found in the best writers.
The following inversions of the augmented sixth are used.

lowered.

augmented sixth whenever the supertonic harmony was used (ex-
cept with the notes marked x).

How is the chord of augmented sixth formed?
What progressions has it?
Which member of the chord is generally used as a bass?
Between which two members of the chord does the interval of the augmented
sixth lie that gives the chord its name?
Is the succession by lowering the third possible with this chord?
Chord of Augmented Fifth.
This chord may be produced in two ways : —
First, by chromatically raising the fifth of a Major chord.
Second, by chromatically lowering the root of a Minor chord.
The raised fifth must ascend ; any chord may follow that includes
the note to which the raised fifth ascends.
The fifth of the Dominant chord in Major keys may be raised when
the seventh is added; in general the raised fifth is put above the
seventh.

The augmented fifth chord, produced by lowering the root of a

tonic (Example 1 ), or by the dominant (Example 2 ) of its relative
major.
It is never inverted, being quite ineffective except with the root at

seventh ; thus, first, third, fourth, fifth resemble dominant, followed
by tonic; 2 is like a dominant with second progression.
5. Tonic with passing seventh, with fifth at bass.
When the passing seventh is Major, which is only so with the
Tonic and Subdominant chords, the augmented fifth is often used
with it.

Suspensions.
( Note. Suspension and Retardation are treated in a new way in this work, the intention
being to bring out clearly the difference between them.)
The seventh and ninth, Major or Minor, may be added to any com-
mon chord by Suspension; i. e., by tying the note that becomes the
seventh or ninth from a preceding chord in which it is a consonant
member ( root, third, or fifth ) .
The Suspended seventh and ninth resolve by descending one degree.
The remaining notes follow the rules given for the progression of
the dominant seventh and ninth {
1. Supertonic harmony; tonic, dominant; descending by whole-
tones.
2. The same, with supertonic harmony changed to augmented
sixth.
3. Augmented sixth and dominant, descending by whole-tones;
i. e., the roots.
4. Same, descending by half-tones; i. e., the roots.
Of course the sequence may be stopped at any point, when the key
is reached to which it is wished to make a transition.
Sequences may be made by means of the second and third pro-
gressions of the dominant, also with dominant eleventh.

The pupil should write and play these sequences in all the keys
repeatedly, and should invent new ones, make inversions of them,
and arrange the chords in different ways.
If the plan of instruction mapped out in this book has been care-
fully followed, and each step mastered before proceeding to the next,
above all, if the Relationship of Keys making up the " Group " is
well understood, the pupil will have a knowledge and command of
the resources of harmony that will amply repay the time and labor
spent in acquiring them.

Tempered Scale.
There is among musicians such a vague notion as to what is meant
by the tempered scale, that it has been thought well to add a few
explanatory words, avoiding all minute details as much as pos-
sible.
To make all our chords in perfect tune it would be necessary to
divide the octave into so many parts that the result would be an un-
manageable mass of sounds ; but it was discovered that by dividing the
octave as nearly as possible into twelve equal parts, a series of sounds
was obtained, which while not corresponding exactly with the true
series, was yet so near that every sound in the series might be the
root, third, fifth, seventh, etc., in some chord, so nearly in tune that
the ear was satisfied.
. The gain to music was not alone in the simplification of the scale,
but, what was of far greater importance, the power of passing at
will from any key to any other, by taking advantage of the sounds
they hold in common,
On this modern music is founded. It is hardly too much to say
that modern music dates from the publication of the "Well Tem-
pered Clavier."
Practically the "tempering" of the scale is secured by a very sim-
ple means; viz., by tuning every fifth slightly flat. This secures the
twelvefold division of the octave.
The ratio between the vibrations, per second, of a given note and
its octave is i to 2 ; that is, the octave vibrates twice as fast. The
ratio between the vibrations, per second, of a given note and its
fifth is 2 to 3 ; that is, the fifth vibrates one-half faster than the
root.

Now suppose we begin with C, and tune in fifths and octaves as in
the following diagram.

It will be seen that by tuning up twelve fifths and down six oc-
taves, the octave of the first note is reached.
Now, if we allow 144 vibrations to the starting note, the octave
must have 2S8 ; but the C reached by the tuning given above will
have about 290, so that it is too sharp, about the one-eighth of a tone.
Tempering is dividing this small interval, called the comma of
Pythagoras from its reputed discoverer, as equally as possible among
the twelve fifths. The result is that the octave is the only interval in
our system that is perfectly in tune.
Below will be found the first six of the above sounds, with their
vibration numbers attached. It is an easy arithmetical problem to
find the rest. To find the fifth of a given sound, add half the num-
ber to itself; thus, C, 144; G, 216, because the half of 144 is 72,
and 72 and 144 are 216. When the octave below is to be found,
divide the number by 2.

It is not necessary here to go any deeper into this subject. The
student who wishes to become thoroughly acquainted with it will
find it exhaustively treated in many works on acoustics, especially in
Helmholtz, Tyndal, Blaserna, etc. There is also an excellent trea-
tise in 44 Grove's Dictionary," under the title Temperament.
The regret is often expressed that musicians do not adopt a more
perfect scale, but it should not be forgotten that custom rules in this

as in many other things. From our earliest infancy we are habit-
uated to the tempered scale.
It is the scale that has given us all the greatest music we possess;
it satisfied the musical instincts of Bach, Haydn, Mozart, Beethoven,
Mendelssohn, and countless others among the greatest composers.
Music means something more than mere sweet sound. To one
who feels this meaning, no possible exactness of intonation would
add to it in, say, the slow movement of the Sonata Path^tique (I
choose an illustration from piano music because the chief scorn of
the purists is directed against the piano), while on the other hand it
would quite destroy the unexpected modulation from A\> to E, and
back again.
There is but one way in which a change in our scale may be intro-
duced : some great composer must arise who will show us that its
possibilities for expression far surpass those of the tempered scale.
FIGURED BASS.
Called also Erroneously Thorough Bass, (Italian) Basso
Continuo, (German) General Bass.
Figured bass was devised as a sort of musical shorthand, by means
of which the chord each bass note was to bear was represented
by figures placed under or over the bass. Its use dates from about
the year 1600. It was intended to serve as a guide to the accom-
panist, to whose discretion it was left to arrange the harmony as he
pleased. It may easily be guessed that accompaniment did not have
the importance in the estimation of the old composers that it has in
their modern successors.
By one of those strange chances that so often happen, figured bass
has assumed a position never contemplated by its inventors, through
its adoption as the means of teaching harmony. Its original purpose
has long been disused, although conservatism still demands ''playing

from figured bass " as one of the exercises for candidates for degrees
at some universities.
It may be easily understood that it is quite possible for any one to
write over a given series of notes the intervals indicated by the fig-
ures, without having the least conception of the reasons for the
combinations or for their successions. Just as one may learn the
Greek alphabet so as to pronounce with facility the Greek language,
yet without knowing the meaning of a single word.
The principles upon which the system of figured bass is con-
structed are easily understood, and to anyone who has mastered the
system of harmony taught in this book, they offer no difficulties.
The simple combinations and successions of the older writers may
be represented with comparatively little complexity, but the most
ardent advocates of figured bass admit that the amount of complica-
tion made necessary in the figuring by the complexity of modern
music, is such that its unravelment becomes a veritable enigma.
The rules upon which the system is based are as follows (the
figures indicate the intervals over the bass):
When a note is without figures it bears the common chord.
1. But it is sometimes necessary, as for example, when a given
note is to bear two or more chords, to indicate the common chord by

a 3, or 5, or 6 or 5, etc. (As a general thing, the 3 is sufficient.)
2. The position of the chord is left entirely to the discretion, or
the reverse, of the student.

There are two exceptions, viz., the augmented sixth is indicated by
a six with a line through it, thus, the augmented fourth is indi-
cated in the same way,
When a note is common to two or more chords in succession, its
repetition is indicated by means of short horizontal lines (1).
A long line placed after the figures, over the first note of a running
or arpeggioed bass, means that the chord is to be held until the end
of the line (2).
When there are several sets of figures over a single note, care must
be taken to get the value of the notes in which the chords are written
correctly. When there are two or four sets of figures over a note,
there is no difficulty; but when there are three or any other odd
number, it is not so easy to tell just how the values are to be dis-

trihuted. This is indicated in some degree by. the position of the
figures in the measure ; thus,
Various attempts have been made to improve on this system of
figured bass by the use of additional signs, but the increase in the
number of signs only increases the complexity.
One plan largely adopted, is to indicate the degree of the scale that
is the root of the chord by means of Roman numerals under the
chords.
Thus, 3 signifies that the chord is an inversion of the chord whose
V
root is the fifth of the scale.
Another plan that has never become general uses the letters of the
alphabet to indicate the member of the chord that is used as a bass ;
thus,
A signifies that the root is at the bass.
B signifies that the third is at the bass.
C signifies that the fifth is at the bass.
D signifies that the seventh is at the bass.
E signifies that the ninth is at the bass.
F signifies that the eleventh is at the bass.
G signifies that the thirteenth is at the bass.

Enough has been written to give the student a thorough under-
standing of the meaning of Figured Bass. Should any one wish to
pursue the subject farther there are innumerable text-books based on
this system that may be consulted.
That good musicians may be trained by this system countless num-
bers attest. We only claim for the system set forth here, that it
reaches the same results by a shorter and pleasanter route.
