Although there are a few note-additions in this period, the tendency overall is to have note-diminution. The rhythm is augmented (32nds become 16th triplets) from measure 15 to 16. The rest of the period stays in this 16th triplet subdivision with a small addition of 32nd triplets from measure 20 onward. After the diminuendo in bar 15, the dynamics evolve in crescendo from piano in measure 16 towards forte in measure 20 and move back in diminuendo in the last two measures of the period. No accents are added and the phrasing remains static. The melodic curve begins quite fluent at measure 15, moves to a more capricious middle part, and ends quite fluent again in measure 22.
