On the eighteenth of May I took my new duet and my violin, and went again to Herr Tietz, whom I this time found alone. It did not require much to persuade him to play the duet; but he would not take the primo. We had hardly ended, when Herr Hirschfeld, hornist in the Imperial orchestra, and others with whom I was unacquainted, came in. Herr Tietz begged me to repeat the duet, and it appeared to please not him alone, but also the others. […]Tietz played the secondo of my duet, which is not easy, without faltering and perfectly clean, executing the cantabile passages with taste and feeling. The passages which, according to the old method, he played with rebounding bow, pleased me less.
