Dearest Count 
                of Music
                     On the best paper I 
                possess I am writing to ask you to be so kind as to play in the 
                septet [Opus 20] at Odescalchi's tomorrow. Schindlecker is not 
                here. So if you don't play, the whole musical performance will 
                have to be cancelled; and in that case I shall be most certainly 
                suspected of having omitted to do something.-Therefore I beg you, 
                dear C[ount] of M[usic], not to refuse to do me this favour. You 
                will certainly be treated with the greatest distinction. Prince 
                Odescalchi himself will write to you tomorrow morning about this 
                - The rehearsal is at eleven o'clock tomorrow morning. I am sending 
                you the score so that you may have a look at the solo part in 
                the last minuet, which, as you know is the most difficult - I 
                am expecting you - 
                                                                                                  Your
                                                                                                              Bthvn
