A Treatise on

Simple Counterpoint
in

Forty Lessons

PREFACE

The purpose of this work is to supply the need in the Oberlin
Conservatory of Music of a text-book on Simple Counterpoint containing
a definite assignment of lessons, and affording more practice
than usual in combining species.

It is a treatise on strict counterpoint, but strict in a limited sense
only. In two-part counterpoint with other than the first species in
both parts, dissonances are permitted under certain conditions, and
in three- and four-part writing the unprepared seventh and ninth,
and the six-four chord, are allowed in certain ways.

While the illustrations have been written in close score, it is
nevertheless urged that all exercises be written out in open score,
as the movement of the different parts is thus more clearly seen.

The use of the C-clefs is left optional with the teacher.

A knowledge of harmony is presupposed, hence nothing is said
pertaining to it.

The author wishes to express his indebtedness to Professor A.E.
Heacox for his help and advice.

SIMPLE COUNTERPOINT

LESSON I

Counterpoint is the art of combining two or more melodies of
equal melodic individuality.

In simple counterpoint all parts must remain in the same
relative position to one another.

The Cantus Firmus is a given melodic phrase that is to receive
contrapuntal treatment, that is, one or more parts are to be added
above or below it.

The Counterpoint is any part other than the Cantus Firmus.

Intervals are harmonic or melodic.

An Harmonic interval is the difference in pitch between two
tones sounding at the same time.

A Melodic interval is the difference in pitch between two
tones sounded in succession by the same voice. [Fig. 1.]

Fig. 1.

Harmonic intervals are divided into Consonances and Dissonances.

Consonances are classed as perfect or imperfect.

The Perfect consonances are the Unison, Fifth, and Octave.
[Fig. 2a.]

The Imperfect consonances are the Major and Minor Thirds
and Sixths. [Fig. 2b.]

All other intervals are dissonances.

Fig. 2.

A Diatonic progression is one in which both name and pitch
are changed. [Fig. 3a.]

A Chromatic progression is one in which the pitch is changed
a semitone, while the name remains the same. [Fig. 3b.]

Fig. 3.

Progression from one chord to another is called Harmonic progression;
from one tone to another, Melodic progression.

In melodic progression all major, minor, perfect and diminished
intervals are allowed except the major and minor seventh. The
minor seventh may, however, be used when harmony does not
change (a). [Fig. 4.]

Fig. 4.

In counterpoint there are Five Species, or orders. When the
counterpoint has one note for each note of the cantus firmus, it is
of the First Species (a); if it has two notes for each note of the
cantus firmus, it is the Second Species (b); if four notes, the
Third Species (c); if two notes syncopated, the Fourth Species (d);
and a mixture of these species is the Fifth Species, or Florid
Counterpoint (e). [Fig. 5.]

Fig. 5.

SIMPLE COUNTERPOINT IN TWO PARTS

FIRST SPECIES

Two-part counterpoint comprises a cantus firmus and a counterpoint.
[Fig. 6.]

Fig. 6.

Although in two-part counterpoint we have to deal with intervals,
rather than harmonies, still the harmonic progressions represented
by these intervals should be regarded.

The exercises should begin and close with tonic harmony. At
the beginning the unison, fifth or octave, and at the close the unison
or octave, are permitted. [Fig. 7.]

Fig. 7.

After the first measure it is better to use imperfect consonances
only. The perfect consonances, however, may be used
sparingly when a more melodious counterpoint is thereby obtained.

The unison may be used in the first and last measures
only. [Fig. 7.]

All progressions must be diatonic, and parts should not cross.

The repetition of a note in a lower part should be avoided
wherever possible. In a higher part, repetition to the extent of
three notes in succession is allowed.

Do not use more than three thirds or sixths in succession.
[Fig. 8.]

Fig. 8.

Successive similar skips, except the minor third (a), in one
direction, are to be avoided. Successive skips of a fourth are
good when the tones are the fifths of the triads on I, IV and vii°.
The last tone should return one degree (b). [Fig. 9.]

Do not move more than an octave in one direction in two
skips. [Fig. 9c.]

Fig. 9.

Covered fifths and octaves, except from I to V, or V to I, are
forbidden. [Fig. 10.]

Fig. 10.

Both parts skipping in contrary motion to a fifth or octave
should be avoided in two-part writing. [Fig. 11.]

Fig. 11.

Avoid consecutive perfect intervals. [Fig. 12.]

Fig. 12.

The augmented fourth (Tritone) is not only considered bad
as a melodic interval by some authorities, but its appearance between
different parts in successive intervals is also prohibited.
This prohibition, however, holds good only when the chords in
which it appears are in fundamental position, as in Fig. 13a.
This is shown by the fact, that if one part skips as at b, there is
no unpleasant effect.

Fig. 13.

Avoid consecutive major thirds in major keys. In minor keys
they are good. [Fig. 14.]

Fig. 14.

Use adjacent voices in writing, and do not exceed the vocal
compass of a voice.

Modulation may be resorted to within the exercises, but only
to nearly related keys; for example, in C, to G, F, a, e, or d.

At the close parts should proceed stepwise to the unison, or
octave. [Fig. 15a.]

A close as in Fig. 15b may be used occasionally. In this case
the leading-tone is better in the higher part.

Fig. 15.

EXERCISES

To each of the following canti firmi write two counterpoints above, and
two below.

Canti Firmi

Fig. 16.

LESSON II

SECOND SPECIES

Fig. 17.

All rules for the first species must be observed.

Two notes are written in the counterpoint to one of the cantus
firmus, except in the last measure. [Fig. 18a.] In the last measure
but one the first species may sometimes be used. [Fig. 18b.]

Fig. 18.

Repetition of a note in any but the first species is forbidden.
[Fig. 19.]

Fig. 19.

The counterpoint may begin on the first or the second half of
the measure, preference being given to the second half. When
it begins on the first half it must be a unison, fifth, or octave;
when on the second half, it may be any consonance. [Fig. 20.]

Fig. 20.

After the first measure the interval on the first beat should be
an imperfect consonance, as in the first species, but the fifth, or
octave, may be used occasionally.

In this and succeeding lessons, all notes in the measure not
belonging to the harmony implied on the first beat, must be
treated as dissonances, e.g., those belonging to the implied harmony
may be left by a skip (a) or stepwise progression (b) unless
dissonant with the cantus firmus; then avoid their use; if foreign

[7]

to it, whether consonant (c) with the C.F. or not (d), they
must be treated as embellishments or passing-tones. [Fig. 21.]

Fig. 21.

The embellishment may be used as follows: when above the
principal tone, it may be a semitone (a) or a whole tone (b) distant
from it; and when below, a semitone (c). [Fig. 22.]

Fig. 22.

When the counterpoint is below the cantus firmus, the fifth of
the chord needs special treatment. It is permitted on the weak
beat when the lower is treated as an harmonic passing-tone.

An harmonic passing-tone is the second of three tones belonging
to the same chord. [Fig. 23a.] While the third tone should
be a member of the chord containing the fifth as an harmonic
passing-tone, the chord above it may change as in Fig. 23b.

The fifth is permitted on the strong beat when it is only an
implied fifth (six-four chord); that is, the third and fifth appear
on the strong beat, and the root does not come in until the second
half of the measure. [Fig. 23c.]

Fig. 23.

The unison is permitted on the weak beat. [Fig. 24.]

Fig. 24.

Avoid broken-chord effects, that is, do not use more than three
tones belonging to the same chord in succession. [Fig. 25.]

Fig. 25.

Avoid frequent skipping of parts. [Fig. 26.]

Fig. 26.

Parts may cross occasionally, but should return immediately
[Fig. 27.]

Fig. 27.

Consecutive fifths or octaves on consecutive strong beats are
bad; but they are good on the weak beats if the second fifth or octave
is approached in the opposite direction from the first. [Fig. 28.]

Fig. 28.

In minor the sixth degree may occasionally be raised on the
strong beat, if it is desired to proceed upward to the raised
seventh degree. [Fig. 29.]

Fig. 29.

In the last measure but one, both the supertonic and leading
tone should appear. [Fig. 30.]

Fig. 30.

Three notes may be written to one of the cantus firmus, as in
Fig. 31. For this no new rules are required.

Fig. 31.

The cadences in Fig. 32 are good. It will be seen that the
cadences of the first species may also be used.

Fig. 32.

EXERCISES

To cantus firmus a write two counterpoints above and two below in the
first species.

To cantus firmus b write two above and two below in the second species.

Canti Firmi

Fig. 33.

LESSON III

SECOND SPECIES IN BOTH PARTS[A]

Fig. 34.

When writing second species in both parts no cantus firmus is
used, both parts being original. One part begins on the first beat,
the other may begin on either the first or second beat. [Fig. 35.]

Fig. 35.

The interval formed by the two notes appearing on the second
beat should be a consonance, or one of the following dissonances:
The augmented fourth, the diminished fifth, the minor or diminished
seventh when properly resolved, and the perfect fourth
when approached in contrary motion.

All tones not belonging to the harmony implied on the first
beat, must be treated as dissonances. [Fig. 36.]

Fig. 36.

The seventh or ninth of the implied harmony of a measure,
when approached in an upward direction, may be used in either
part, provided it is consonant with the other part, or comes within
the requirements of the exceptions. [Fig. 37.]

The passing major seventh and its root may appear on the
weak beat, even when approached in similar motion as in Fig. 37a.
The seventh must then be treated as a passing-tone.

Fig. 37.

The cadences in Fig. 38 are good when writing second species
in both parts. Those having the second species in one part only,
may also be used.

Fig. 38.

Writing the second species in both parts will, in this lesson, be
confined to a mixture of the first and second species, as in Fig. 39.

In this do not use the second species more than four measures
continuously in one part. It will be noticed that the second
species may occasionally be used in both parts. In later lessons
opportunity will be given to write it continuously in both parts.

Fig. 39.

EXERCISES

Write two eight-measure phrases mixing the first and second species.
[Fig. 39.]

To cantus firmus a write one counterpoint above and one below, three
notes to the measure. [Fig. 31.]

To cantus firmus b write one above and one below, in the second species.

Canti Firmi

Fig. 40.

LESSON IV

THIRD SPECIES

Fig. 41.

In this species, four notes are written in the counterpoint to
each note of the cantus firmus. The counterpoint may begin on
the first, second, or fourth quarter. The second quarter is, however,
the most usual. [Fig. 42.]

Fig. 42.

The exercises should begin and end with tonic harmony.

When the counterpoint begins on the first quarter it must
form a perfect consonance with the cantus firmus. When on the
second or fourth quarter, any consonance may be used.

All previous rules are to be regarded, unless exceptions are
made.

At least one of the first three quarter-notes of a measure
should be left degreewise. [Fig. 43.]

Fig. 43.

The last quarter of a measure is usually left degreewise. If
approached by a skip or by a degreewise progression of at least
two quarter-notes, it may be left by a skip in the opposite direction
from which it was approached. A skip of a third in the same direction
is also good when this skip is preceded by a skip of a
third (d). [Fig. 44.]

Fig. 44.

Parts may cross occasionally.

The use of non-harmonic tones, as in Fig. 45, is good in either
part. At a the passing-tone, instead of progressing directly to
the adjacent chord-tone, skips a third to the other side of it and
then returns. The embellishment is treated in the same way, but

[13]

is most effective when the principal tone is the leading-tone, as
at b. In both cases the counterpoint should continue degreewise
through the chord-tone. [Fig. 45.]

Fig. 45.

The fifth, when in the lower part, may be used on any but the
first quarter, provided it is treated as a passing-tone, e.g., approached
and left by stepwise progression in one direction.

Fig. 46.

Consecutive fifths and octaves are forbidden when appearing
on the accented beats of successive measures; between prominent
notes of successive measures not more than four quarters apart;
and between a prominent note of one measure and the first quarter
of the next. [Fig. 47.]

Fig. 47.

Oblique motion to the unison is bad. It is permitted if it continues
in the same direction through the unison. [Fig. 48.]

Fig. 48.

The unison may be used on any but the first quarter of a
measure.

Frequent repetition of a figure as in Fig. 49 is not good.

Fig. 49.

The embellishment may be used either above or below, whether
a semitone or a whole tone; but when it is a whole tone below, it
is most satisfactory as the ninth of the implied chord. [Fig. 50.]

Fig. 50.

In minor the sixth and seventh degrees of the scale are raised
both ascending and descending, when used in harmonies containing
the leading-tone as a chord-tone. They are unaltered both ascending
and descending in harmonies containing the sixth degree
of the scale as a chord-tone. In other harmonies they are raised
in ascending only.

The sixth or seventh degrees may be chromatically altered
with only one note intervening. [Fig. 51.]

Fig. 51.

Six notes may be written to one of the cantus firmus, as in
Fig. 52.

Fig. 52.

The cadences in Fig. 53 are good.

Fig. 53.

EXERCISES

To cantus firmus a write three counterpoints above and three below, in the
third species.

Write two eight-measure phrases, using second species continuously in
both parts. [Fig. 34.]

Cantus Firmus

Fig. 54.

LESSON V

THIRD SPECIES IN BOTH PARTS

Fig. 55.

The suggestions given for writing second species in both parts
apply here, except that when both parts move degreewise, any interval
may come on the second and fourth quarters, preferably a
consonance. The third quarter is treated the same as the second
half when writing the second species in both parts.

The augmented fourth, and diminished fifth and seventh, may
be approached in similar motion. [Fig. 56.]

Fig. 56.

The augmented fourth following the perfect fourth, as in
Fig. 56a, is good.

The minor seventh, and the major and minor ninth of a chord,
may be used freely on any but the first quarter, but must be consonant
with the other part. [Fig. 57.]

Fig. 57.

The first and third species may be mixed, as in Fig. 58.

Fig. 58.

The second species may be used in one part and the third in
the other, also six notes in one part and two in the other, and six
in one and three in the other. All tones appearing simultaneously,
must comply with the suggestions for tones appearing on the weak
beat given in previous lessons, where both parts have other than
the first species. [Fig. 59.]

Fig. 59.

The cadences in Fig. 60 are good, and will suggest others.

Fig. 60.

EXERCISES

To cantus firmus a write one counterpoint above and one below, in the
third species.

To cantus firmus b write counterpoints in six notes, one above and one
below. [Fig. 52.]

Write one eight-measure phrase, mixing the first and third species.
[Fig. 58.]

Write two eight-measure phrases, using third species in both parts.
[Fig. 55.]

Canti Firmi

Fig. 61.

LESSON VI

FOURTH SPECIES

Fig. 62.

This species is the same as the second, except that the last
note of the measure is tied to the first note of the next, forming
a syncopation. As in the second species, the first note of the
counterpoint should form a unison, octave or fifth, and when the
counterpoint begins on the second half it may also be an imperfect
consonance.

When the counterpoint begins on the first half, the second half
is treated the same as the second half of succeeding measures,
described in the next paragraph.

After the first measure, the second half of the measure should
contain a consonance (Fig. 63a), the first half a consonance (b),
or dissonance (c), preferably the latter, in which case a suspension
is formed. This is the most desirable form of syncopation. When
the first half contains a dissonance, the counterpoint must descend—or
ascend in retardation (d)—one degree to an imperfect
consonance (c). When the first half is a consonance, it may
be left by a skip to some other chord-tone (e), or by degreewise
progression (f). In the latter case the second note is non-harmonic,
and therefore should not be used to prepare a syncopation
except as in Fig. 63d (Retardation of the root in I₆).

Fig. 63.

When writing three notes to one in the fourth species, the
suspension may resolve on the second beat (a), or the third (b).
In the latter case, the suspension skips (c) to some other chord-tone,
before resolving. The resolution to the leading-tone (d)
forms an important exception to this rule. [Fig. 64.]

Fig. 64.

The fifth may be used in the lower part if it becomes the preparation
of a suspension (Fig. 65a). It may also be used in the
lower part, as in Fig. 65b, provided it resolves by skipping to the
third of the chord.

In skipping from the fifth to the root, or the reverse, in the
lower part, do so in an upward direction. The fifth, when treated
as an harmonic passing-tone, may, however, be approached either
ascending or descending.

Fig. 65.

The retardation should be used only when prepared by the
leading-tone. It rises a semitone in resolving. [Fig. 66.]

Fig. 66.

The following dissonant intervals may be used on the first half of
the measure:—When the counterpoint is above, the fourth and
seventh in suspension, and second and fifth in retardation; and
when below, the second in suspension, and the fourth and seventh
in retardation. [Fig. 67.]

Fig. 67.

Consecutive fifths on consecutive strong beats of the measure
are good when one of the tones of the second fifth is prepared, as
in Fig. 68.

Fig. 68.

The following cadences are good:

Fig. 69.

EXERCISES

Write one eight-measure phrase with two notes to the measure in one part
and six in the other; one with three notes in one and six in the other; and
one with two notes in one part and four in the other. (Fig. 59.) In combining
the species in this and succeeding lessons the student may place any
species in any part.

To the cantus firmus write two counterpoints above and two below, in the
fourth species.

Cantus Firmus

Fig. 70.

LESSON VII

FOURTH SPECIES (Continued)

The first and fourth species may be mixed as in Fig. 71.
Rules for writing other than the first species in both parts are to
be regarded.

Fig. 71.

EXERCISES

To cantus firmus a write two counterpoints above and two below, in the
fourth species.

To cantus firmus b write two above and two below, three half-notes to the
measure, with syncopations.

Write two eight-measure phrases, mixing the first and fourth species.

Canti Firmi

Fig. 72.

LESSON VIII

COMBINING THE FOURTH SPECIES WITH THE OTHERS

All previous rules for combining species still apply.

In combining the fourth species with other than the first, the
following intervals may be used on the first half of the measure,
in addition to those mentioned in Lesson VI: When the counterpoint
is below, the fourth, fifth and seventh in suspension, and
the ninth in retardation; and when above, the fifth in suspension,
and the seventh in retardation; but in every such case the part
having other than the fourth species must skip to some other
chord-tone before resolving the suspension. [Fig. 73.]

Fig. 73.

The leading-tone may be doubled as in Fig. 74. Here the
leading-tone that is prepared skips to some other chord-tone,
while the new leading-tone remains stationary.

Fig. 74.

The minor or diminished seventh, major or minor ninth, may
be used as preparation of a suspension in either part, provided it
is approached by a skip in an upward direction, and is consonant
with the other part, or is one of the permitted dissonances.
[Fig. 75.]

Fig. 75.

The fourth species may be combined with the second or third
species, and two or three notes syncopated may be written in one
part with six in the other. [Fig. 76.]

Fig. 76.

EXERCISES

To the cantus firmus write one counterpoint above and one below, in the
fourth species.

Write one eight-measure phrase each, of the following combinations:
The fourth species with the second; the fourth with the third; two notes
syncopated against six notes; and three notes syncopated against six notes.
Write some in major and some in minor. [Fig. 76.]

Cantus Firmus

Fig. 77.

LESSON IX

FIFTH SPECIES: FLORID COUNTERPOINT

Fig. 78.

Florid counterpoint is a mixture of the second, third and fourth
species.

In addition to these species eighth-notes may be used in groups
of two on the second and fourth quarters of the measure. Both
notes should be approached and left stepwise, with the exception
that the first may be taken by a skip. [Fig. 79.]

Fig. 79.

Not more than one and one-half measures of any one species
should be used continuously in one part. [Fig. 80.]

Fig. 80.

In the use of quarter-notes it is necessary to exercise care.
They may be used on the first half when preceded by quarter-notes,
when the entire measure is filled, or when they precede
a half-note which is the preparation of a suspension. On the
second half they are always good. [Fig. 81.]

Fig. 81.

For the present the suspension should not be less than a half-note
or its rhythmic equivalent in the ornamental resolution.

In this species the suspension may resolve ornamentally, that
is, it may have some note or notes interpolated between the suspension
and its resolution. The relative position of the suspension
and its resolution must remain the same as in the regular
resolution. [Fig. 82.]

When the suspension is left by a leap, the note skipped to
should be consonant with the other part (b). When eighth-notes
are used, as at a, they must be approached and left stepwise.

The suspension, instead of being sustained as a half-note, may
be repeated on the second quarter, as at c. In this case it is
best to continue stepwise through the tone of resolution.

At d the resolution, instead of coming on the second half,
appears on the quarters on either side. This is good.

Fig. 82.

The ornamental resolution may be used in either part.

Use the suspension freely.

The solutions should be musical, and are to be written over
and over again until such are secured.

All cadences of the second, third and fourth species, or any
combination of these, may be used.

EXERCISES

To canti firmi a and b write two counterpoints above and two below, in
the fifth species

Canti Firmi

Fig. 83.

LESSON X

FLORID COUNTERPOINT (Continued)

When florid counterpoint is combined with other than first
species, the dotted half followed by a quarter-note (a), or two

[25]

eighth-notes (b), is good. Also, a rhythmic figure, as at c, where
a half-note occupies the second and third quarters, may be used.
[Fig. 84.]

Fig. 84.

EXERCISES

Write one eight-measure phrase, each, of the following combinations:
The fifth species with the second; the fifth with the third; and the fifth with
the fourth. Write also two eight-measure phrases with fifth species in both
parts. [Fig. 85.]

Fig. 85.

SIMPLE COUNTERPOINT IN THREE PARTS

LESSON XI

FIRST SPECIES

Fig. 86.

Regard all rules for two-part counterpoint, unless otherwise
mentioned.

If possible, each measure should contain a complete chord.
When in the first species it becomes necessary to double an interval,
let it be preferably the root. The third should be doubled
only when a decidedly smoother melodic progression is thereby
obtained; and when both thirds are in outer parts, each should be
approached and left stepwise in one direction (Fig. 87). The
doubling of the fifth is, of course, impossible, since it necessitates
the omission of the third.

Fig. 87.

All triads may be used in their first inversion.

Diminished and augmented triads, however, are best used in
their first inversion.

The six-four chord may be used at the close as the cadencing
tonic six-four chord. Do not approach the root and fifth in similar
motion, as at b. [Fig. 88.]

Fig. 88.

The dominant seventh may be used in any but its second inversion,
the fifth being omitted.[A] The seventh requires no preparation.
Other chords of the seventh are better not used until
second species and later.

If possible, let the chord in the first measure appear complete.
The last chord but one should be complete, unless some form of
V or V₇ is used. [Fig. 89.]

Fig. 89.

Consecutive major thirds may be used when three or more
parts are employed. [Fig. 90.]

Fig. 90.

A note may now be repeated in the lowest part when it becomes
the seventh of a dominant seventh-chord. [Fig. 91.]

Fig. 91.

In writing, use soprano, alto and tenor, or alto, tenor and bass;
and do not separate upper parts more than an octave. For a
chord or two they may (for the sake of better voice-leading) separate
a tenth.

All hidden fifths and octaves are bad, except between I and V
and V and I. [Fig. 92a, b.]

The perfect fifth following the diminished fifth is good when
taken in an upward direction stepwise in the higher parts.
[Fig. 92c.]

Fig. 92.

All cadences used in harmony are good.

Unless otherwise mentioned, put the cantus firmus in any part,
but avoid its continued use in the same part.

EXERCISES

To canti firmi a and b write the first species in all parts. Write each
three times, setting the cantus firmus in a different part in each solution.
This necessitates transposing the cantus firmus, when setting it in the other
parts.

Canti Firmi

Fig. 93.

LESSON XII

THE SECOND SPECIES

Fig. 94.

The second species is written in one part and the first in the
other two.

All suggestions made for the second species in two-part counterpoint
are to be observed, unless otherwise mentioned. Those
regarding consecutive perfect intervals are especially to be
observed.

The fifth, when in the lowest voice, should be used as in two-part
counterpoint, except when used in V⁴₃ or the cadencing tonic
six-four chord.

The V⁴₃ chord may be used on the weak beat, necessitating
the omission of the third. [Fig. 95a.]

The third may be omitted (b), or doubled (c), on the weak
beat in this and succeeding species. [Fig. 95.]

Fig. 95.

The minor or diminished seventh may be approached by a skip
in an upward direction on the weak beat in any part. This
usually necessitates the omission of some other chord-member on
the weak beat.

The major or minor ninth may also be used in the same way,
except in the lowest part, provided it is at least a ninth above the
root. [Fig. 96.]

Fig. 96.

The progression from vii°₆ to V in root-position or any inversion
in the same measure, is good. [Fig. 97.] Use b and c only
when using other than first species in two or more parts.

Fig. 97.

Each measure should usually contain a complete chord. If not
complete on the first beat, bring the missing interval in on the
second. [Fig. 98.]

Fig. 98.

The cadences in Fig. 99 are good, and will suggest others.
The use of the fourth species is permitted as at a. A note may
be repeated in the final cadence in all species as at b.

Fig. 99.

EXERCISES

To cantus firmus a write the first species in all parts, as previously
directed.

To cantus firmus b write second species in one part. Write three times,
changing cantus firmus and counterpoint about so that they will appear in
each part in turn.

Canti Firmi

Fig. 100.

LESSON XIII

SECOND SPECIES IN TWO PARTS

Fig. 101.

The suggestions for second species in both parts, in two-part
counterpoint, apply for the two parts having the second species
in three-part counterpoint.

Accidental harmonies sometimes appear on the weak beat.
All tones in this accidental harmony foreign to the chord on the
strong beat must be treated as dissonances. This must be regarded
whenever two or more parts have other than the first
species. [Fig. 102.]

Fig. 102.

At Fig. 102a, the accidental harmony f-a-c is on the weak
beat. The f and a, being foreign to the chord c-e-g on the strong
beat, are correctly treated as dissonances. At b, the f and a are
left by skip, which is not permitted.

The second species may be written continuously in all parts;
the tones appearing on the weak beat must be harmonically related
to one another, and those foreign to the chord on the strong
beat must be treated as dissonances. [Fig. 103.]

Fig. 103.

The first and second species may be mixed, as in Fig. 104.

Fig. 104.

The cadences in Fig. 105 are good, and will suggest others.
Those with first species in all parts may also be used.

Fig. 105.

EXERCISES

To cantus firmus a write a counterpoint in the second species in one part.
Write three settings, as directed in the previous lesson.

Write two eight-measure phrases mixing the first and second species in all
parts.

To cantus firmus b write counterpoints in the second species in the other
two parts. Write two settings, with the cantus firmus in different parts.

LESSON XIV

THIRD SPECIES

Fig. 107.

The suggestions for third species in two-part counterpoint, as
well as those for writing the second species in three-part counterpoint,
apply when writing third species in three-part counterpoint.

The cadences at Fig. 108 are good, and will suggest others.

Fig. 108.

EXERCISES

To cantus firmus a write third species in one part. Write three settings
as previously directed.

To cantus firmus b write second species in two parts, as previously
directed.

Write one eight-measure phrase, using second species in all parts.

Canti Firmi

Fig. 109.

LESSON XV

THIRD SPECIES IN TWO OR MORE PARTS

Fig. 110.

Previous suggestions when two or more parts have other than
first species, apply here.

In using the ninth of a chord it is well to keep it at least a
seventh distant from the third, as well as a ninth above the root,
except in the case of the dominant ninth in minor keys, where it
may be separated by only an augmented second ([b]). [Fig. 111.]

Fig. 111.

In writing the third species in all parts, notes appearing simultaneously
should be harmonically related. Treat all tones foreign
to the chord on the first quarter as dissonances.

The cadences in Fig. 112 are good.

Fig. 112.

EXERCISES

To cantus firmus a write third species in one part, as previously directed.

To cantus firmus b write third species in two parts, as in Fig. 110b.
Write twice, changing the cantus firmus about.

LESSON XVII

FOURTH SPECIES

Fig. 116.

When the syncopation is a suspension or retardation, it is
treated the same as in harmony.

The retardation should always be prepared by the leading-tone.

When the syncopated note belongs to the harmony of the measure,
it may be left by a skip or stepwise progression. [Fig. 117.]

Fig. 117.

The third may be omitted on the strong beat in this species,
provided the part having fourth species skips to the missing third,
as at Fig. 117a.

Consecutive fifths, but not octaves, are saved by the suspension.
Whenever they occur, do not use the note of resolution as

[38]

preparation of a suspension, or tie it into the next measure (a),
since it is really the passing seventh, and that does not lend itself
well to either of the above, except in sequence as at b. [Fig. 118.]

Fig. 118.

The seventh or ninth of a chord, except the major seventh,
may be used as preparation of a suspension when approached by
a skip in an upward direction, as in Fig. 119.

Fig. 119.

This species may also be written in triple rhythm. [Fig. 120.]

Fig. 120.

The cadences in Fig. 121 are good, as well as those of the
second species.

LESSON XXII

FIFTH SPECIES IN ALL PARTS

EXERCISES

Write five eight-measure phrases with fifth species in all parts, making
use of imitation at the beginning as in Fig. 131. The imitation need only be
relative and continue for three or four notes. It is also well, when a part uses
a striking melodic figure, to have some other part imitate it immediately
after.

Fig. 131.

SIMPLE COUNTERPOINT IN FOUR PARTS

LESSON XXIII

Fig. 132.

No new suggestions are needed, except as follows: All covered
fifths and octaves permitted in harmony are allowed here.

Let the parts begin one after the other in imitation. [Fig. 151.]

LESSON XXXIII

FLORID MELODIES AS CANTI FIRMI
FREE HARMONIZATION IN TWO-PART COUNTERPOINT

Fig. 152.

Thus far, all notes in the measure foreign to the harmony
on the first beat were treated as dissonances. Now, the cantus
firmus may be harmonized at pleasure, the only restriction being
that any tone foreign to the chord with which it enters must be
treated as a dissonance. [Fig. 152.]

It is not necessary that each part be strictly florid, but that
the effect of the parts as a whole should be so. This applies
from this point to the end of these lessons.

The suspension may now be a quarter-note, or its rhythmic
equivalent. It then comes on the first (a) or third (b) quarter
of the measure, and the resolution on the quarter following. The
preparation should be as long as, or longer than, the suspension.
[Fig. 153.]

Fig. 153.

The eighth-note as in Fig. 154a is good. It should be used
only on the second half of a weak beat, and be preceded by a dotted
quarter-note. Sixteenth-notes may be used in place of the
eighth-note, but should be approached and left step-wise. [Fig. 154b.]

Fig. 154.

The first species may be employed occasionally in the course
of an exercise.

Make plentiful use of imitation.

When more than one line of a choral is used, it may be treated
by having the other parts continue through the holds, as at a, or
letting them rest, as at b. [Fig. 155.]

When, in place of the hold, the movement continues, it is
necessary to interpolate a full measure in place of the hold.
[Fig. 155 and Fig. 159.]

Fig. 155.

The note under the hold may be continued the extra measure,
or the part may rest and then reënter. All that is required is that
it begin after the lapse of one measure, i.e., when the line ends on
the accent the next line begins on the weak beat of the measure
following, and if it ends on the weak beat then on the accent of
the next measure.

The interval at any hold except the last of a choral may be
either a perfect (a) or imperfect consonance (b). [Fig. 156.]

Fig. 156.

Modulation often occurs at the holds. If so, make it clear.

In this and in succeeding lessons set the cantus firmus in any
part, and transpose if necessary.

EXERCISES

To cantus firmus b write two counterpoints above and two below.

To cantus firmus a write one above and one below, with both parts resting
at the hold. Also do the same with the counterpoint continuing at the
hold. [Fig. 155a, b.]

Canti Firmi

Fig. 157.

LESSON XXXIV

FREE HARMONIZATION IN THREE-PART COUNTERPOINT

When writing in three or more parts, it is well to let a part
rest occasionally, and, when it reënters, have it imitate one of the
other parts. [Fig. 158.]

Fig. 158.

EXERCISES

To cantus firmus a write two counterpoints above and two below in two-part
counterpoint.

Write two original eight-measure phrases in two-part counterpoint.
