Measures 9–16 develop the flowing pattern through changing harmonies and registers, with accented longer tones emerging above the smaller notes. The second ending begins in measure 17 with a softer continuation. Measures 19–25 grow more forceful, descend into the lower register, and sweep upward before the final chords.","created_at":"2026-09-11T18:50:16+00:00","first_published_at":null,"published_at":null,"updated_at":"2026-09-13T05:06:37+00:00","match_basis":"filters"}
