Dear Mayer!
                      Please 
                request Herr von Seyfried to conduct my opera today. I want to 
                see and hear it myself today at a distance. At all events my patience 
                will not then be so severely tried as it would be if I were near 
                the orchestra and had to listen to the murdering of my music! 
                - I cannot but think that this is being done on purpose. I shall 
                not say anything about the wind-instruments but - that all the 
                pianissimos and crescendos, all the decrescendos and all fortes 
                and fortissimos should have been deleted from my opera! In any 
                case they are not all observed. All desire to compose anything 
                more ceases completely if I have to hear my work performed like 
                that! -
                      Tomorrow 
                or the day after I shall fetch you for dinner. Today I am rather 
                ill again. Your friend
                                  Beethoven
                      PS. 
                If the opera is to be performed the day after tomorrow, then we 
                must have another rehearsal in the room tomorrow - If not, things 
                will be worse every day!
