# Analysis result

The dossier presents a D-major, 3/4 keyboard-texture movement. At the marked candidate (window W3), the opening theme returns almost literally, but the entry is harmonized off-tonic: the first measure sits on a B-major sonority (E015), the second over an A bass functioning as dominant (E016), and the home tonic D is regained only at the third measure (E017), from which point the music matches the opening nearly note-for-note (E017–E018 vs. E003–E004). The incipit itself is transposed down a step (G–A–G in E015 versus A–B–A in E001). After a brief chromatic divergence (E019–E020), the continuation settles into repeated dominant-seventh-to-tonic figuration in D (E021–E026), behaving like a recapitulation with a recomposed interior rather than ongoing development. The location, roughly 51% through the second part, is fully compatible with a recapitulatory division. On balance the evidence favors an off-tonic recapitulation that funnels to the tonic within two measures, with a genuine tonic double return two bars later being the main alternative reading.

## Limitations

Missing dossier evidence: no tempo, instrumentation, or full-movement context; windows are excerpts, so the exposition–development boundary and any repeat structure are unobservable, limiting the proportional and rotational judgments. No dynamics exist outside three markings, weakening the rhetorical cue. Analytical uncertainty: the marked candidate falls two measures before literal tonic-plus-theme alignment, so the split between off-tonic recapitulation and tonic double return depends on where one locates the return, not on missing data. Style felt generically familiar (galant keyboard idiom), reported only via suspected_recognition; no work-level identification was made or used.
