Measures 9–18 repeat and intensify the pattern before a transition into the lower register. Measures 19–28 place sustained upper chords above flowing bass arpeggios and then return to the opening motion. Measures 29–36 extend the arpeggios through wide registral exchanges and a quieter cadence. Measures 37–46 rebuild from broken-chord fragments to a two-hand arpeggiated climax and final chords.","created_at":"2026-09-16T06:23:18+00:00","first_published_at":"2026-09-16T06:23:44+00:00","published_at":"2026-09-16T06:23:44+00:00","updated_at":"2026-09-16T06:23:44+00:00","match_basis":"filters"}],"latest_catalog_version":23356,"source_lag_revisions":0}
