Measures 13–24 transfer the running motion to the upper register over syncopated bass harmony and expand into broader arpeggios. Measures 25–36 combine both registers in rising sequences and alternating accented figures. Measures 37–46 unfold in contrary-motion broken chords before a short chordal close.","created_at":"2026-09-16T06:19:53+00:00","first_published_at":"2026-09-16T06:20:17+00:00","published_at":"2026-09-16T06:20:17+00:00","updated_at":"2026-09-16T06:20:17+00:00","match_basis":"filters"}
