Its continuous exchange of quick notes and broader leaps gives the music a concentrated, energetic character.\r\nThe opening arpeggio idea moves between the hands, expanding into sequences and descending answers. More chromatic passages briefly interrupt the clear outlines of the theme, while short rests separate some of the later exchanges. The opening idea returns before a rising sequence and final descending figures bring the piece back to A minor.\r\nAn interesting detail is how the arpeggio figure changes direction and register while retaining its rhythm, allowing a small opening idea to shape nearly the entire piece.","created_at":"2024-04-29T17:35:20+00:00","first_published_at":null,"published_at":null,"updated_at":"2026-09-23T06:16:40+00:00","match_basis":"filters"} Full response metadata (including counts, interpretation and alternate links): { "projection_revision": 2, "snapshot": "40899ee732c8a9d86f9dcf2825f62031", "catalog_version": 22726, "snapshot_created_at": "2026-09-30T21:24:54+00:00", "snapshot_expires_at": "2026-10-01T21:24:54+00:00", "source_changed_at": "2026-09-30T21:24:47+00:00", "freshness_behavior": "materialized on first request after a committed source change; database triggers cover row writes and relationship writes", "source_id_sha256": "994fa5919fcfaa761d9e52bb21239a18675af0c2368c42c518c82742206b2c30", "source_content_sha256": "3be166ec97d00bfb58d3768897e742d25d3b57bcc642ed57e48a6daa26037627", "total_catalog_pieces": 6434, "schema_version": "2.0", "query": "", "normalized_query": "", "resolved_filters": { "piece_id": 2567, "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/2567?page=1&piece_id=2567&projection=full&snapshot=40899ee732c8a9d86f9dcf2825f62031", "json": "https://roadtovirtuosity.com/ai/catalog/pieces/2567.json?page=1&piece_id=2567&projection=full&snapshot=40899ee732c8a9d86f9dcf2825f62031", "text": "https://roadtovirtuosity.com/ai/catalog/pieces/2567.txt?page=1&piece_id=2567&projection=full&snapshot=40899ee732c8a9d86f9dcf2825f62031" }, "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.
