Its broad opening Allegro, compact Andante, and sparkling final Rondo each give the melody a different rhythmic setting.\r\nThe first movement opens with a rising melody over an even broken-chord accompaniment. More animated figures lead to a sweet contrasting theme and quick scale passages. The middle section reshapes the opening gestures, adds darker harmonies and active bass replies, then leads back to the main theme. The returning material closes with an upward rush and firm chords.\r\nThe Andante shifts to F major and a lilting 6/8 meter. Short dotted gestures and singing phrases rest above gently pulsing chords; fuller harmonies and increasingly decorated melodic turns provide contrast within its two repeated sections.\r\nThe Rondo restores C major with a buoyant dotted theme, quick turns, and clipped chordal replies. Recurring statements alternate with running episodes and a broader melodic passage above repeated accompaniment figures. After the main theme returns, an extended coda exchanges flowing figures between registers, recalls the tune softly, and rises to a decisive close.\r\nInteresting fact: the slow movement occupies only one page in this edition, while each outer movement spans five—a striking contrast in scale within the same sonatina.","created_at":"2024-05-09T22:06:33+00:00","first_published_at":null,"published_at":null,"updated_at":"2026-09-23T15:26:04+00:00","match_basis":"filters"}],"latest_catalog_version":23386,"source_lag_revisions":0}
