	Elaboration consists chiefly of the regular and irregular employment of auxiliary notes in connection with essential notes. When such employment occurs at regular intervals, a pattern or figure is the result, as in Ex. 30. The simplest form of such elaboration is when the several notes of a chord are spread in arpeggio, and each preceded by an auxiliary note, as in Ex. 29. The best method of memorizing such a passage seems to be, first, to regard it in its plain form, Ex. 29 a, and then, recognising the principle upon which the elaboration is framed, to add it afterwards (as in Ex. 25). In the following passage every second note will be seen to consist of a lower auxiliary note resolving on an essential note a semitone higher:—

	In cases where a figure or pattern is formed, as in Ex. 30, the relative position of the auxiliary note in the figure should be noted. 56. The Progression of Figures.—The progression of a figure may be either (a) scalewise, (b) according to the intervals of a chord, or (c) according to some other regularly recurring interval. In either case such progression may be retained intellectually. Ex. 30 shows a figure whose initial notes proceed according to the scale of D minor :—
