Dear Riess
Most
earnestly do I beseech you to arrange for me to have the wind-instrument
parts today. Although I have tried to let you off this task, you
must also check the violin parts; and that must be done today,
because, as no doubt you are aware, there is to be a rehearsal
on the following day. [Anderson footnote: "Probably for Beethoven's
concert on April 5, 1803, in the Theater an der Wien, at which
his oratorio 'Christus am Ölberge' (Op. 85), his first and
second symphonies (Op. 21 and 36) and his third pianoforte concerto
(Op. 37) were performed.]
