Measures 16–39 develop the material through chromatic harmonies and exchanges of the flowing accompaniment between the hands. The opening melodic gesture returns at the end of measure 40. Its continuation expands into fuller harmonies and lower-register phrases, then quietens over repeated bass notes before the final detached notes and rests.","created_at":"2026-09-12T00:18:18+00:00","first_published_at":null,"published_at":null,"updated_at":"2026-09-12T00:18:37+00:00","match_basis":"filters"}],"latest_catalog_version":22971,"source_lag_revisions":0}
