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.

Fragment of Beethoven.] [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.
