Biamonti 472 – Sketch for Piano, Grasnick Notebook No. 3, Sheet 38, Second Page, Lines 2 and 3 (Dagmar Weise, page 138). Final months of 1808.

This sketch is preserved in Berlin at the Staatsbibliothek, within the sketchbook known as “Grasnick 3,” specifically on sheet 38v, lines 2–3. It is a brief pianistic fragment, not attributable to any known Beethoven work, and thus classified by Dagmar Weise as “unbekannt” (unknown). The absence of a manuscript facsimile for this page prevents reproduction of the sketch.
