This very natural, and fairly common, inequality increases the difficulty of a.n.a.lysis somewhat. A knowledge of the princ.i.p.al chords, and familiarity with their manner of employment in composition, greatly facilitates the task, because the harmonic design furnishes in many cases the only unmistakable clue to the extremities of the melodic members. The difficulty finally vanishes only when the student has learned to appreciate the declamatory quality of all good melody, and can detect its inflections, its pauses; can _feel_ which (and how many) of its tones are coherent and inseparable, and where the points of repose interrupt the current, and thus divulge the sense of the melodic sentence.

LESSON 3.--a.n.a.lyze the third Song Without Words of Mendelssohn (A major, the so-called Hunting Song); first of all, locate the princ.i.p.al melody,--it is not always the uppermost line of tones; then divide this melody into its melodic motives, marking the "breaks" which separate each from the following one; the figures may be noted, also, but only mentally. No. 35 may also be a.n.a.lyzed in the same manner.

CHAPTER IV. THE PHRASE.

THE PHRASE.--It is not altogether easy to give a precise definition of the phrase. Like so many of the factors which enter into the composition of this most abstract, ideal, and intangible of the arts, the phrase demands considerable lat.i.tude of treatment, and will not readily submit to strict limitations or absolute technical conditions.

Perhaps the most correct definition is, that the term phrase is equivalent to "sentence," and represents the smallest musical section that expresses a _complete_ idea; not necessarily wholly finished, and therefore independent of other adjoining phrases, but at least as complete _in itself_ as is an ordinary brief sentence in grammar, with its subject, predicate, and object. It should be sufficiently long to establish the sense of tonality, the consciousness of beginning, course, and ending, and should exhibit a certain (though limited) amount of palpable and satisfying melodic and harmonic contents. For this reason, the Phrase, and nothing smaller, should be regarded as the structural basis of musical form.

The factors defined in the preceding chapter (the figure and motive) are, as a rule, decidedly less than is demanded of a complete phrase, which--as has been intimated--usually consists in the union of two (possibly more) motives,--just as the motive is compounded of figures, and the latter of single tones.

In some, comparatively rare, cases the composer gives a phrase an independent place upon his page, as complete miniature sentence, not directly connected with other phrases. This may be seen, very plainly, at the beginning (the first four or five measures) of the Songs Without Words, Nos. 28, 41, 35, 3, 4, 16. Examine each, carefully, and the nature of the phrase in its most definite form will become apparent.

Such independent phrases are most likely to be found, like the above, at the beginning or end of a larger composition, to which they are related indirectly, as isolated introduction, or postlude. Thus, the following complete phrase appears at the beginning of a song:

[Ill.u.s.tration: Example 15. Fragment of Schubert.]

Its division into two melodic motives, and the subdivision of these into figures, is plainly marked.

When the phrase a.s.sumes such a conspicuous position, and is so complete and definite in its effect as the ones just seen, there is naturally no difficulty in recognizing and defining its extremities. But the task of phrase a.n.a.lysis is by no means always thus easy.

LENGTH OF THE REGULAR PHRASE.--Fortunately for the work of a.n.a.lysis, there are certain established landmarks of forms, so conscientiously observed, and so firmly grounded in the practices of cla.s.sic writing (because the necessary consequences of natural law), that it is generally practicable to fix fairly regular and plausible boundaries to the phrase, notwithstanding the freedom and elasticity which characterize the application of the syntactic principle in music.

Therefore the student will find that a phrase, in the great majority of cases, covers exactly _four measures_, and will seldom be misled if he looks for the end of his phrase four measures beyond its beginning.

This refers, be it understood, only to measures of average size (in the ordinary time denominations, 3-4, 4-4, 6-8 measure). If the measures are uncommonly large (9-8, 12-8), the phrase will probably cover no more than two of them; or, if small (2-4, or 3-4 in rapid tempo), the phrase may extend to the eighth measure. The operation of this four-measure rule is exhibited with striking regularity and persistence in the _Jugend Alb.u.m_ of Schumann (op. 68); throughout its forty-three numbers there are probably no more than a half-dozen phrases whose length differs from this standard. For example:

[Ill.u.s.tration: Example 16. Fragment of Schumann, Op. 68, No. 11.]

It will be observed that the first (and also the third) of these phrases consists of two exactly similar two-measure motives. This seems to lend some confirmation to the idea of a two-measure phrase; but the student is warned against deviating from his four-measure standard, upon such evidence as this. Many instances will be found, like these, in which the impression of a complete phrase is not gained until the motive of two measures has been thus repeated; _the repet.i.tion is necessary_, in order to finish the sentence, and this proves that the two measures alone do not const.i.tute the "complete idea" which we expect the phrase to represent.

The same regularity of dimension will usually be found in all kinds of dance music; in technical exercises (for instance, the etudes of Czerny and others); and in all music of a simple or popular character.

EXCEPTIONS.--In its ordinary, normal condition the phrase is a musical sentence four measures in length. But this rule has its necessary exceptions; necessary because, as we have learned, the principle of Variety is quite as vital as that of Unity or symmetry. The phrase is not always regular; by various means and for various reasons, it occasionally a.s.sumes an irregular form. When such irregular phrases are encountered (phrases of less or more than four measures) the student will best distinguish them by defining their extremities, their beginning and ending--as "beginning" and "ending," without reference to their length. This should not be attended with any serious difficulty; at least not to the observant student who reads his musical page thoughtfully, and attaches some meaning to the figures and motives of the melody; who endeavors to recognize the extent to which the successive tones appear to cling together (like the letters in a word) and const.i.tute an unbroken melodic number,--and, in so doing, also recognizes the points where this continuity is broken, and a new number is announced. Much a.s.sistance may be derived from the fact--striking in its simplicity--that the ending of one phrase defines, at the same time, the beginning of the next, and _vice versa_. The locating of one, therefore, serves to locate the other. There is, usually, something sufficiently indicative about a "beginning," to render it noticeable to a careful observer, and the same is true of an "ending."

This is ill.u.s.trated in the following:

[Ill.u.s.tration: Example 17. Fragments of Beethoven.]

No. 1 is from the pianoforte sonata, op. 10, No. 3, second movement; see the original. This phrase exhibits an ending, unmistakably, in the _fifth_ measure, and not in the fourth. Its form is therefore irregular.

In No. 2 (from the first pianoforte sonata), the first phrase ends with the fourth measure, obviously, for the evidence of a new "beginning" in the following measure is perfectly clear; the phrase is therefore regular. But the next phrase runs on to the _sixth_ measure from this point (the tenth from the beginning of the whole), because there is no earlier evidence of an "ending." Observe that the first phrase has a preliminary quarter-note, the second phrase none. Turning to Mendelssohn's Songs Without Words, the very first (introductory) phrase of No. 3 is five measures in length; the first one in No. 35 also contains five measures; the first one in No. 16, and in No. 9, contains three measures. The irregular phrase will be again considered (in a different aspect) in a later chapter.

The recognition of these syntactic traits of the melodic sentence is of great moment to the player, for they const.i.tute the information upon which conscious, intelligent, effective _phrasing_ depends; and without intelligent phrasing, without a clear exposition of the formation and arrangement of the members and phrases, full comprehension and adequate enjoyment of a musical composition is impossible.

CONTENTS OF THE PHRASE.--The question may arise, what is it that makes a phrase,--the rhythm, harmony, or melody? Strictly speaking, all three; for music subsists in the ceaseless co-operation of these three primary elements of composition, and no phrase is wholly complete without the evidence of each and all. Generalizing the definitions already given, the function of each of these primary elements may be thus described: The element of harmony regulates the choice of the tones that are to sound together; the upright shafts of tone (chords) which determine the _body_, or framework, of the music. The element of melody regulates the choice of single tones, selected from the successive shafts of harmony, that are to form a connected line or strand of tones (in horizontal order, so to speak),--something like a chain or chains stretched from harmonic post to post, which describe the figure or _outline_ of the musical image. The element of rhythm gives the whole body its _life_,--regulates the choice of varying lengths, defining the infinitely varied "tapping" of the musical mechanism.

It is evident, from this, that no vivid, satisfying musical impression can be created in the absence of any one of these essential elements.

But, for all that, they are not of equal importance; and, in determining the extremities of the phrase (and of all other factors of musical structure), the melody takes precedence over harmony and rhythm. That is to say, that in his a.n.a.lysis of figures, motives, phrases, periods, and so forth, the student's attention should be centered upon the melody,--that chain of successive single tones which, as repeatedly stated, usually describes the _uppermost_ line of the harmonic and rhythmic body. That is the reason why the ill.u.s.trations given in this book are so frequently limited to the melody alone; it is the pencil point which traces the design, describes the form, of the musical composition.

LESSON 4.--Procure the _Jugend Alb.u.m_, op. 68, of Schumann, and mark the phrases in Nos. 1, 2, 4, 5, 6, 7, 8, 9, 13, 18, 20, and others. In the given numbers the phrases are all regular,--four measures in length.

a.n.a.lyze in the same manner Mendelssohn's Songs Without Words, Nos. 27, 22 (first phrase, five measures), 48, 28, 35, and others; occasional irregularities may be encountered.

Also Beethoven, pianoforte sonata; op. 14, No. 2, second movement (C major, _andante_); and op. 26, first movement.

A few cautious experiments may also be made in a.n.a.lyzing any composition which the student may chance to be studying, especially if not too elaborate. The necessary safeguard consists in simply pa.s.sing over every confusing point, limiting the a.n.a.lysis to those phrases that are self defining, for the present,--until greater experience and fuller information shall have been gained.

CHAPTER V. CADENCES.

CADENCES IN GENERAL.--A cadence is the ending of a phrase. Strictly speaking, every interruption or "break" between figures, and between all melodic members, is a cadence; but the term "cadence" is applied to nothing smaller than entire phrases.

The cadence is the point of Repose which creates the necessary contrast with the condition of Action that prevails more or less constantly during the phrase; and the effect of this point of repose is, therefore, to separate one phrase from the next. The cadential effect is generally produced by two or three chords, the last one of which is called the cadence-chord, and stands, when the cadence is perfectly regular, upon an accented beat of the final measure. This, according to our definition of the phrase, will most commonly be the fourth measure.

For example:

[Ill.u.s.tration: Example 18. Fragment of Schumann.]

The first chord in the fourth measure, on the accented beat, is the "cadence-chord"; but the preceding chord (and possibly the one before that, also) is naturally inseparable from the final one, and therefore the entire cadence would be defined technically as embracing both (or all three) of these chords. The effect of repose is obtained _by the length of the final chord_, which exceeds that of any other melody tone in the phrase; its time-value is a dotted quarter, because of the preliminary tone (_e_, before the first accent) which, in the original (op. 68, No. 28), precedes the next phrase in exactly the same manner.

Ill.u.s.trations of the regular cadence will be found, also, in Ex. 15 and Ex. 16; in the latter,--consisting as it does of four consecutive phrases, four cadences occur, distinctly marked by the _longer tone_ on the accented beat of each successive fourth measure.

MODIFICATION OR DISGUISING OF THE CADENCE.--The most natural and characteristic indication of a cadence is the _longer tone_, seen in the examples to which reference has just been made; for a tone of greater length than its fellows is, in itself, the most conclusive evidence of a point of repose, as compared with the shorter tones in the course of the sentence, whose more prompt succession indicates the action of the phrase. (See Ex. 29.)

From this the student is not to conclude that every long tone marks a cadence. The rhythmic design of a melody is obtained by a constant interchange of long and short tones, without direct reference to the cadence alone; and numerous examples will be found in which tones of equal, or even greater, length than the cadence-tone occur in the course of the phrase. We have already seen that the end of a motive, or even of a figure, may be marked by a longer tone, or its equivalent in rests; and have been taught to expect a cadence in the fourth measure only, as a rule.

But the direct evidence of a cadence afforded by a longer tone is considered not only unnecessary, but in many cases distinctly undesirable. While cadences are indispensable, in music of clearly recognizable form, it is equally true that they must not be so emphatic as to check the current of melody and harmony too frequently or completely, or destroy the continuity and coherence of the members.

And it is therefore an almost invariable practice, especially in music of a higher order, to modify and disguise the cadences by some means or other; that is, to diminish the weight of the characteristic "longer tone,"--to counteract, partially or entirely, the impression of actual cadential cessation, by continuing (instead of interrupting) the rhythmic pulse. This is so very common, and so confusing a device, that the effect of the various methods employed to conceal or disguise a cadence must be thoroughly understood.

It is necessary to remember, always, the rule that governs the actual body of the phrase, and its possible preliminary tones; namely, that the vital, essential starting-point of a phrase (and other factors of musical form) is _the first primary accent_, the first beat of the first _full_ measure. The length of the phrase is reckoned from this point, and consequently, the cadence-chord is ent.i.tled to all the beats that remain, from its accent to the very end of the final measure. For example:

[Ill.u.s.tration: Example 19. Fragment of Mozart.]

In this case the cadence-chord is not modified or disguised in the least, but takes full advantage of the six beats that make the sum of the fourth measure.
