Lessons in Music Form. Percy Goetschius
strongest tone-line is therefore apt to be designated, somewhat unfairly, the melody (the "tune" or "air" is more just). But, at all events, this predominating melodic line is the most important factor of the form, the one upon which the definition and recognition of the "form" depend; and it is therefore necessary that the student learn to distinguish it, to acquire the habit of centring his attention upon it—in reading, listening to, or analyzing music; and, in playing, to give it the emphasis it requires.
The importance of a tone-line depends solely upon its conspicuousness. The principal melody—the Melody—is the one which is most salient, which most attracts the hearer's attention. For this reason the composer is induced to place his chief melody above the rest of the tone-lines, because the uppermost tone strikes the ear more acutely than the lower ones, and therefore the succession of highest tones constitutes a conspicuous line that attracts and impresses the sense most keenly.
Here then, at the top of the harmonic tone-complex, we look for the chief melody; and here it will be found—excepting when arbitrary emphasis (by accentuation) is imparted to some lower tone-line, so that it, for the time being, assumes a prominence equal, or superior, to that of the uppermost line. (This divided prominence is seen in the 18th Song Without Words—the duet.)

CHAPTER III. FIGURE AND MOTIVE.
THE MELODIC FIGURE.—The smallest unit in musical composition is the single tone. The smallest cluster of successive tones (from two to four or five in number) that will convey a definite musical impression, as miniature musical idea, is called a Figure. Assuming the single tone to represent the same unit of expression as a letter of the alphabet, the melodic figure would be defined as the equivalent of a complete (small) word;—pursuing the comparison further, a series of figures constitutes the melodic Motive, equivalent to the smallest group of words (a subject with its article and adjective, for example); and two or three motives make a Phrase, equivalent to the complete, though comparatively brief, sentence (subject, predicate, and object). This definition, amply illustrated in the following examples, serves also to point out the significant resemblance between the structure of language and of music. The principal melody is, as it were, the voice of the speaker, whose message is framed wholly out of the primary tones, or letters of the musical alphabet. The association of primary tone-units, in successive order, results first in the figure, then in the motive, then the phrase, period, and so forth, in the manner of natural growth, till the narrative is ended. The following example, though extending beyond our present point of observation, is given as an illustration of this accumulative process (up to the so-called Period):—

[Illustration: Example 6 continued.]
The tones bracketed a are the Figures; two (in the last measures, three) of these are seen to form Motives; two of these motives make the Phrase; and the whole sentence, of two phrases, is a Period. See also Ex. 1 and Ex. 2, in which the formation of figures is very distinct.
The pregnancy and significance of each of these tiny musical "words" (or figures, as we are to call them)—small and apparently imperfect as they are—can best be tested by concentrating the attention upon each as if it stood alone upon the page; it is such vitality of the separate particles that invests a musical masterwork with its power and permanency of interest.
DEFINING THE FIGURES.—It is not always easy to distinguish the figures in a melodic sentence. While they are unquestionably analogous to the words in speech, they are by no means as concrete, nor are they separated as distinctly, as the words upon a written or printed sheet. This is in keeping with the intangible quality of music, and the peculiar vagueness of its medium of expression; the quality which veils its intrinsic purport from the mass of music admirers, and lends it such exquisite and inexplicable charm to all hearers alike.
In a word, it is not the common practice for a composer to cut up his melodic sentences into separately recognizable small particles, by distinctly marking each component figure. Here and there it is done, by way of contrast, or emphasis, or for a definite rhythmic effect—as shown in Ex. 2 and Ex. 6. But more generally the figures are so closely interlinked that the whole sentence may impress the hearer as one coherent strain, with an occasional interruption. The very minute "breaks" between figures are often nearly or quite imperceptible; and in many cases it is possible to define the figures of a motive in various, equally plausible ways, simply because the "breaks" (which are of course surely present, and become more and more apparent between the larger members of a composition) are likely to be too inconsiderable among these, smallest factors of the melodic form.
The following three guides may serve to indicate the extremities of the melodic figures:—
(1) A brief rest, or a longer tone, usually marks the end of a figure. This is fully illustrated in Ex. 6. See also Ex. 10, Ex. 12.
(2) Similarity of formation (rhythm and melodic direction) almost invariably defines the mutually opposed, and therefore separable, divisions of the melody—both small and large. For example (the figures are bracketed a):—
