Beethoven spent a great deal of time on the concerto in estimated late 1814 and early 1815. He made about seventy pages of
sketches for the first
movement, and even started writing out a
full score (
Artaria 184 in the
Staatsbibliothek zu Berlin). The score runs almost uninterrupted from the beginning of the movement to the middle of the solo
exposition (
bar 182), although the scoring becomes patchy as the work proceeds and there are signs of indecision or dissatisfaction on the composer's part. This partial movement (known as Hess 15) A completion of the first movement was reconstructed by British scholar
Nicholas Cook in 1987. ==References==
