 Its 32 bars though do not subdivide into four eight-bar periods but into sections of bars with six motivically distinct modifications of the original semiquaver triplet figure, thus offering an attractive break from the symmetry.An effective dynamic increase begins in bar 23 but does not end in a climax as the crescendo does not lead to fortissimo but eases off in diminuendos (bars 36 and 40).Harmonically the section (bars 23–41) may be interpreted as an extended and ornamented D-flat major cadence.
