In measures 9–24, a dolce espressivo upper melody unfolds over repeated lower chords, growing fuller before easing back. Measures 25–44 bring back the opening rhythmic figure, then build through rising lines and denser chords. Measures 45–55 introduce a more animated lower line beneath the upper part’s short figures. At measure 56, Tempo 1º returns with broad chords and high notes; the texture later thins toward a brief return of the opening rhythm. Measures 73–94 move from spare high notes over repeated lower notes to fuller chords and rapid rising figures, then settle into a sustained trill and a final chord.","created_at":"2026-09-16T07:41:50+00:00","first_published_at":"2026-09-16T18:57:37+00:00","published_at":"2026-09-16T18:57:37+00:00","updated_at":"2026-09-16T18:57:37+00:00","match_basis":"filters"} Full response metadata (including counts, interpretation and alternate links): { "projection_revision": 2, "snapshot": "853a31700bad760646625b796fb31fee", "catalog_version": 23486, "snapshot_created_at": "2026-10-01T15:25:07+00:00", "snapshot_expires_at": "2026-10-02T15:25:07+00:00", "source_changed_at": "2026-10-01T15:23:25+00:00", "freshness_behavior": "materialized on first request after a committed source change; database triggers cover row writes and relationship writes", "source_id_sha256": "7b911d1e027bf4b7123a91d0adbda10e2a97955c00cbf742039001a349d3d252", "source_content_sha256": "c2000615e48074e68612e3b46f90e6f52293b253993e2372504cc871edfbe78c", "total_catalog_pieces": 6551, "schema_version": "2.0", "query": "", "normalized_query": "", "resolved_filters": { "piece_id": 5171, "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/5171?page=1&piece_id=5171&projection=full&snapshot=853a31700bad760646625b796fb31fee", "json": "https://roadtovirtuosity.com/ai/catalog/pieces/5171.json?page=1&piece_id=5171&projection=full&snapshot=853a31700bad760646625b796fb31fee", "text": "https://roadtovirtuosity.com/ai/catalog/pieces/5171.txt?page=1&piece_id=5171&projection=full&snapshot=853a31700bad760646625b796fb31fee" }, "warnings": [ "Strict taxonomy filters exclude unattributed records; search title text separately before deciding something is missing.", "Work identity, musical sequence and completeness are unknown unless reviewed metadata is supplied.
