Variation 1, mm. 33–48, replaces the melody’s longer tones with dotted, slurred running figures above short offbeat lower notes; its signed return closes at the local Fine in m. 40. Variation 2, mm. 49–72, begins Un poco meno mosso, with repeated upper dyads accompanying the tune in the lower part. Inner repeated notes, shifting melodic roles and a ritardando lead to its quiet close. The Allegro Finale, mm. 73–126, combines light melodic fragments with broader arpeggios, short chromatic runs and repeated lower chords. In mm. 112–118 the lower part moves in quick alternating notes beneath the melody; a descending two-hand scale leads into detached ascending figures, high chord punctuations and the final fermata.","created_at":"2026-09-30T23:24:35+00:00","first_published_at":"2026-09-30T23:24:35+00:00","published_at":"2026-09-30T23:24:35+00:00","updated_at":"2026-09-30T23:24:41+00:00","match_basis":"filters"} Full response metadata (including counts, interpretation and alternate links): { "projection_revision": 6, "snapshot": "1cf7fa00588703c8309209d9bf1e893b", "catalog_version": 33176, "snapshot_created_at": "2026-10-21T14:48:36+00:00", "snapshot_expires_at": "2026-10-22T14:48:36+00:00", "source_changed_at": "2026-10-21T14:44:09+00:00", "freshness_behavior": "materialized on first request after a committed source change; database triggers cover row writes and relationship writes", "source_id_sha256": "457da22ef38bcd9fdeaa58f03fbc0852ae5fcd781ac27592a3f3235d5220a0fa", "source_content_sha256": "d16c7b32243426fbcde1e7f14a5a300ffa7f6714e1e47e408903a6ee4b751885", "total_catalog_pieces": 8266, "canonical_url": "https://roadtovirtuosity.com/ai/catalog/pieces/6766?piece_id=6766", "schema_version": "2.0", "query": "", "normalized_query": "", "resolved_filters": { "piece_id": 6766, "timezone": "UTC" }, "sort": "relevance", "projection": "full", "total_matches": 1, "returned": 1, "page": 1, "per_page": 50, "total_pages": 1, "previous_page_url": null, "next_page_url": null, "end_of_results": true, "alternate_formats": { "html": "https://roadtovirtuosity.com/ai/catalog/pieces/6766?page=1&piece_id=6766&projection=full&snapshot=1cf7fa00588703c8309209d9bf1e893b", "json": "https://roadtovirtuosity.com/ai/catalog/pieces/6766.json?page=1&piece_id=6766&projection=full&snapshot=1cf7fa00588703c8309209d9bf1e893b", "text": "https://roadtovirtuosity.com/ai/catalog/pieces/6766.txt?page=1&piece_id=6766&projection=full&snapshot=1cf7fa00588703c8309209d9bf1e893b" }, "warnings": [ "Archive-only entries have unknown grading status.
