Dear Mayer!
                      Baron 
                Braun informs me that my opera is to be performed on Thursday. 
                When I see you I will tell you why - But I do earnestly beseech 
                you to see that the choruses are still better rehearsed, for the 
                last time they made dreadful mistakes. Furthermore, on Thursday 
                we must have one more rehearsal with full orchestra in the theatre 
                - True, the orchestra did not go wrong, but the performers on 
                the stage did several times - Still, that was to be expected, 
                for the time was too short. I had to take the risk, however, because 
                B[aron] had threatened that if the opera was not performed on 
                Saturday he would have no further performances of it - Knowing 
                the attachment and friendship which you at any rate have always 
                shown to me, I expect you to arrange on this occasion too for 
                these rehearsals. Then the opera will not require such rehearsals 
                any more and you can all produce it whenever you like - Here are 
                two books - please give on to Röckel - All good wishes, dear 
                Mayer, and make this affair of mine your business -
                                                                                                          Your 
                friend
                                                                                                                            Beethov
