Note 161 — Chapter XV
Henry Edward Krehbiel translation
Nottebohm’s study of the sketchbooks used by Beethoven in 1815 (See “Zweit. Beeth.,” pp. 314-20) discloses that he worked upon sketches for works which were never finished—a Symphony in B minor, Pianoforte Concerto in D, and several Fugues, besides experimenting with the opera “Bacchus.” There are also sketches for compositions written in 1816, such as the song-cycle “An die ferne Geliebte” and the Sonata, Op. 101.
