THERE are twenty-seven Variations and a Finale. The theme, like all good subjects for variation, has several well-marked motifs, any of which may be dwelt on and expanded at the composer's pleasure. It is in three sections, the first.and last (of seven bars) alike. Features which are used in development are those in the first two bars-the rise and fall ; in bars 3 and 4—a variant of this figure, with a different rhythm ; in the remaining three bars of this opening section, with a third rhythm, but keeping the rise-and-fall
. movement; and in the middle part of the theme, with its increase of tone as the notes climb up the scale from C to the high A.
