The purpose of this manual is to present the subject matter in centrated form for the use of teachers and students who can devote only a

con-limitedamountoftimetothestudyoftonalcounterpoint

Reference to the eighteenth centuryimplies alimitation inthatweshallnot try to cover all phases of contrapuntal practice which were developed

during the three hundredyears of thereign of tonality.The studentwill be

made acquainted with a style corresponding to that ofthe period in which

the older techniques of counterpointwereintegratedwith themodern idiom

of tonality, a process which found its consummation in the works of*J

S-Bach.

By the same tokenreference to the eighteenth century impliesa

generali-zation, as the technical instructions of this text do not aim at a faithfulreplica of Bach's personal style. This would requirepainstaking analysis of

innumerable details, not only farbeyondthe scope of thisstudy, but also of

a working knowledgeofacertaincompositionalpractice

For this reason we have refrained from quoting examples from Bach's

works Such examples, obviously not written to demonstrate technical cedure,wouldnearlyalwayscontaina numberof detailswhich hadtoremain unexplained forthe timebeing and thuswould tendto confuse the student

Introductory Remarks

The music to which the student is introduced in this outline

is essentially conceived for instruments, mainly such as violin,

violoncello, flute, organ or piano. (While eighteenth century

keyboard music was written for instruments different from the

modern piano, we have become used to disregarding this fact

and find it perfectly satisfactory to perform that music on the

piano.) Even the vocal music of the era of Bach is evidently permeated by the peculiarities of the instrumental style of the

period.

The flexibility of the instruments provides an inexhaustible

wealth of melodic and rhythmic motions, and it is these which are mainly responsible for shadings of mood and expression.

While the music is soulful and sensitive, the emotional

exuber-ance and dramatic intensity, so familiar in the romantic music

ol the nineteenth century, are absent Consequently extreme

contrasts in tempo, range and dynamics are rarely found.

The art of counterpoint consists in regulating the intervals

generated at any given point by the simultaneous progress of

two or more melodic lines according to some principle set up

beforehand and recognized as aesthetically satisfactory. These

principles have varied throughout the history of music, ever

since the idea of polyphony was introduced into the art music

of Western civilization The principle governing eighteenth

cen-tury counterpoint is tonal harmony, in the sense that the combinations arising among the simultaneous melodies are ex-

sound-pected to correspond to the rules established in regard to chord

progressions in the realm of tonality Basic knowledge of these

rulesisa prerequisite for using the present manual.

Syncopation persisting through a series of consecutive beats is not

recom-mended in unaccompanied melodies as it tends to obscure the metric scheme

4 MELODY

The discussion of the following section is devoted to

the study of single-voiced melodies, without point oraccompaniment

counter-A INTERACTION OF PITCH CHANGE AND RHYTHMIC MOTION

The melodies which make up the fabric of polyphony may be understood asmanifestationsofastream ofenergythefluctuations ofwhicharemadeperceptible

in the tones through which the melodic lines proceed Upward motion indicatesincrease of energy, downward motion the opposite Skips indicatesudden changes

of energy (the larger the skip, the more drastic the change), stepwise motionindicatesgradual changes

Thefluctuations of energy indicatedby the motionofthemelodic linethroughvarious pitches are reflected in the rhythmic organization of the melody, i e., in

the relative duration of its tones Small rhythmic values (short tones) condensethe changes of pitch into short time spans and indicate lapid fluctuations of

energy, longrhythmicvalues indicate theopposite.

InExample 12 the release ofenergytakes 17 times asmuch timeas the

build-up (8 quarter notesvs 1eighth note).

Since complete canceling out each other of energy created and expended is

ideally seen as the net result of any musical process, a situation in which theenergy level is zero mustnot be reachedbefore the melody is meant to come to

itsend Inthis respect Examples11 to 13wouldbesatisfactoryonlyifnoation of these melodieswere

Example

Example 14 shows three variants of the same basic melodic design. In 14 a)the rhythmic detail is a little more complex through introducing dotted quarter

Examples 15 to 17 demonstrate other types of melodic design as a result ofcombiningtheelementsstudied sofar

Example 15

In Example 15 the energy manifest in the ascent of thefirst five notesis densed by leturning once more to A (last eighth of the first bar) and used to

con-reach a still higher level F in one straight skip This drastic build-up is

re-leasedover a span of two bars, first bydropping below the level ofthe beginning

downto Gsharp, then swinging backtothis level byreturningto A with anexactretrogressionofthefirst fivenotes

Example 16

Example 16 shows the opposite of the design of Example 13 The energylost

in the downwardskip of anoctave is gradually recoveredintwo ascending moves

While the first of these covers the interval of a sixth (from F to D), the secondspans a seventh (G to F) The larger amount of energy neededfor this greatereffort is symbolized in the accumulation of smaller rhythmic values (sixteenthnotes) inthesecondascent

Example 17

Trang 14

Example 17 being slow lyrical nature, melodic energy fluctuates

within narrower limits and consequently the manifestations of these changes are

less drastic then in the previous examples The idea of the design consists incompensating gradually for the drop ofthe pitch level from Dto E byregainingthe higher level in a series of gently undulating moves Theascent covers exactlytwice as much time as the drop (10 quarter beats vs 5) Accordingto the mood

ofthis melody the ascendingmotion represents reposefullysettlingontheoriginal

Consequently the ascending motion of Example 17 slows down toward the end

(longer rhythmic values), which is the opposite of what happenedin Example 16.

the tonesofthat scale).

In the following examples the chords implied in the melodies are indicated

by the conventional symbols (large Roman numerals for major chords, small

Roman numerals for minor, etc) Since the melodies discussed here are meant

to be played without additional voices or accompaniment, it is not necessary to

thinkoftheharmonic backgroundintermsofan elaborateandconsistentzation Nonetheless the implied chords must be clearly visualized and be repre-sented in the melody through their characteristic tones At least some of thesetones should be placed on accented partsofthe metric scheme because it isthere

Accordingto the nature of tonal harmony and because oftheflexibility ofthemelodic design the chordal implications of a melody may not always be un-equivocal, especially in more complexcases So forinstance theharmoniesunder-lying bars 3 and 4 of Example 18 b) could also be heard as follows:

be-come the leading tone of the dominant key, and that in the minor mode theleading tone must be lowered to become the dominant of the relativemajor

Invention of a melody, then, involves integration blending

elements discussed sofar:

fluctu-ations of energy These must be fitted into the preconceived

metricscheme (accent pattern), and coordinated with the

harmonic background implied in the melodic lineand organized according

totheprinciplesof tonalharmony.

C MELODIC DESIGN IN DETAIL

To accomplish this, the following suggestions should be considered:

a) Skipsshouldbe used mainlyto outline theunderlyingchords

b) Non-chord tones should appear mainly in stepwise motion, as passing oralternatingtones.

c) Rhythmic configurations and melodic elements should be combined so as
