Biamonti 469 – Sketch for Piano, Grasnick Notebook No. 3, Sheet 37, Second Page, Lines 9 and 10 (Dagmar Weise, page 136). Final months of 1808.

This sketch is preserved in Berlin at the Staatsbibliothek, within the sketchbook known as “Grasnick 3,” specifically on sheet 37v, lines 9–10. Dagmar Weise, who transcribed and analyzed the entire notebook, classifies this fragment as “unbekannt”—that is, not attributable to any known Beethoven work. Due to the absence of a manuscript facsimile for this page, the Beethovenian fragment cannot be reproduced.
