Measures 1–8 establish a repeated right-hand bell figure; measure 9 adds the tune in the left hand. At measure 25 the bell figure gives way to a sustained chordal setting. Measure 46 places the melody above the accompaniment through a left-hand crossing. The bell figure returns across contrasting registers before a chordal reprise and a short final flourish.","created_at":"2026-09-22T06:37:29+00:00","first_published_at":"2026-09-22T06:37:29+00:00","published_at":"2026-09-22T06:37:29+00:00","updated_at":"2026-09-22T06:44:58+00:00","match_basis":"filters"}],"latest_catalog_version":25485,"source_lag_revisions":0}
