Biamonti 226 – Presto – Sonata (Sketch), 1799–1800
This sketch is found in Landsberg 7, among the drafts for the third movement of the Sonata in A minor for piano and violin, Opus 23, on page 10 (Mikulicz, page 10). The notebook Landsberg 7, briefly described by Nottebohm (Vol. II, p. 230 ff.), is currently preserved at the Deutsche Staatsbibliothek in Berlin.
The sketch appears on page 10, lines 1–4, and consists of two sections, both marked with repeat signs:
- The first section spans 12 measures, moving from the tonic to the dominant.
- The second section comprises 10 measures, returning from the dominant to the tonic, with the final measure left incomplete and lacking a barline.
The notation is rapid and fragmentary, as Beethoven only writes out the essential parts of the theme, leaving other portions of the measures blank.
A curious detail appears in measure 8: a dotted eighth-note F-sharp whose stem curls upward to the fifth line of the treble clef, then drops down vertically to form the barline. The same graphical flourish is repeated in measure 11, line 1.
In the manuscript, this sonata opening is highlighted and separated from the other sketch on the page by two lines drawn in blue pencil—possibly by Beethoven himself—suggesting a particular interest in this fragment.
In his book Ein Notierungsbuch von Beethoven (Leipzig, Breitkopf & Härtel, 1927), Lothar Mikulicz classifies this sketch as “Unbekannt”, meaning it is not associated with any known Beethoven work.
