Measures 25–44 fragment the motion between registers and build through a broad ascending passage to a fortississimo descent. The opening texture returns at measure 45 before measures 53–68 transfer the running line to the upper part. Measures 69–84 divide the figuration into widely spaced exchanges, and measures 85–96 gather it into a final rise and detached chordal close.","created_at":"2026-09-16T05:18:34+00:00","first_published_at":"2026-09-16T05:18:45+00:00","published_at":"2026-09-16T05:18:45+00:00","updated_at":"2026-09-16T05:18:45+00:00","match_basis":"filters"}
