Small upbeat figures blossom into smooth runs, with the two voices continually answering and overlapping.\r\nThe upper voice starts alone before the lower voice enters with the same curling idea. Sequences shift the material through different harmonies and registers. In the middle, extended trills hold one voice in place while the other continues its flowing line. The opening gestures return, followed by a final exchange of runs and a brief, clear close.\r\nAn interesting detail is the trill passage: the sustained ornament moves from one voice to the other, reversing which part supplies the motion beneath it.","created_at":"2024-04-29T16:40:48+00:00","first_published_at":null,"published_at":null,"updated_at":"2026-09-23T06:08:50+00:00","match_basis":"filters"} Full response metadata (including counts, interpretation and alternate links): { "projection_revision": 2, "snapshot": "dd991bc57de302cf4c85c37ff0c4771c", "catalog_version": 23257, "snapshot_created_at": "2026-10-01T06:56:06+00:00", "snapshot_expires_at": "2026-10-02T06:56:06+00:00", "source_changed_at": "2026-10-01T06:54:01+00:00", "freshness_behavior": "materialized on first request after a committed source change; database triggers cover row writes and relationship writes", "source_id_sha256": "f1f40429b24c3b4ada635b7bdc9d69be1c5ac79eeab819df421c333f1f95902c", "source_content_sha256": "ea904ff74f853fd3545e3127b02e4fca6c949e7c6d6c3b410079e0be75d2d29d", "total_catalog_pieces": 6506, "schema_version": "2.0", "query": "", "normalized_query": "", "resolved_filters": { "piece_id": 2556, "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/2556?page=1&piece_id=2556&projection=full&snapshot=dd991bc57de302cf4c85c37ff0c4771c", "json": "https://roadtovirtuosity.com/ai/catalog/pieces/2556.json?page=1&piece_id=2556&projection=full&snapshot=dd991bc57de302cf4c85c37ff0c4771c", "text": "https://roadtovirtuosity.com/ai/catalog/pieces/2556.txt?page=1&piece_id=2556&projection=full&snapshot=dd991bc57de302cf4c85c37ff0c4771c" }, "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.
