Your FREDERIC. * * * * * _Warsaw, May 15th, 1830._ You will certainly have wondered that Fritz did not answer your letter by return of post; but as I could not immediately give the information you asked for I delayed writing till to-day. Now listen, my dearest, Henrietta Sonntag is coming to Warsaw in June, or, perhaps, at the end of May. I am sure you will not neglect the opportunity of hearing her. Oh, how thankful I am for it. She must be in Danzig now, and from there she comes to us. We have several concerts in prospect. Little Worlitzer, pianist to the King of Prussia, has already been here a fortnight. He plays very finely, and being of Jewish descent, has many natural gifts. He has been with me; he is just sixteen; some of the things he played at our house went famously. His best performance is Moschelesʼs Variations on the Alexander March. He really plays those excellently. You would like his style and manner of playing, although—this to you only—he still lacks much to deserve his title of Chamber _Virtuoso_. There is also a French pianist here, Monsieur Standt. He intended giving a concert, but seems lately to have relinquished the idea. It is an agreeable piece of musical news that Herr Blahetka, father of the _pianiste_ in Vienna, will, if I advise him, come here, when the Diet meets, and give some concerts. But my position is a difficult one; the man wants to make money, and if it happens that his hopes are not fulfilled, he will be angry with me. I answered immediately that I had often been asked whether he would not come, and that many musicians and lovers of music would be glad to hear his daughter; but I did not conceal from him that Sonntag would be here, that Lipinski was coming, that we have only one theatre, and that the expenses of a concert amount to at least 100 thalers. He cannot say now that I did not properly inform him of the state of things. It is very possible that he will come. I should be very glad, and would do all in my power to get a full house for his daughter. I would willingly also play with her on two pianos; for you would not believe how kindly her father interested himself for me in Vienna. [Sidenote: THE NEW CONCERTO.] I do not know yet when I shall commence my journey. I shall probably be here during the hot months. The Italian Opera does not begin in Vienna till September, so I have no occasion to hurry. The Rondo for the new Concerto is not ready yet. I have not been in the right mood to finish it. When the Allegro and Adagio are quite done with, I shall not be in any anxiety about the _Finale_.
