# Identification probe result

## Run metadata

- Case: CASE-DZWT
- Condition: symbolic dossier only (no external lookup performed, per access boundary)

The dossier shows a D major movement in 3/4, opening piano with both hands in bare octaves outlining a zigzag ascent of the tonic triad (D–A, F♯–A, D–F♯, A–D), answered by an eighth-note scale descent over a held dominant-seventh sonority, a witty turn-figure with grace note and staccato/staccatissimo articulation, a B♭-inflected walking-bass digression toward the dominant, and a literal reprise of the opening (window W3, the candidate return) partway through a long second section. This is idiomatic Classical-era keyboard writing in minuet/scherzo or German-dance style, consistent with Haydn, Mozart, Beethoven, or their circle. I considered several specific candidates (Beethoven Op. 10 No. 3 Menuetto, Op. 28 Scherzo, Mozart K. 334 Menuetto, Haydn D major sonata movements) and could not match the incipit to any of them with confidence, so I am reporting a style-level resemblance only rather than a specific identification.

## Limitations

The symbolic encoding omits tempo, instrumentation, and title metadata, and covers only four short windows, so identification rests entirely on the incipit and one internal return. Several Classical D major dance movements share this opening gesture, and my recall of exact incipits for plausible candidates (Beethoven, Haydn, Mozart minuets and scherzos) is unreliable without lookup, which the access boundary forbids. The confidence value reflects the chance that a specific candidate I declined to name is correct; the style-level characterization itself is well supported.
