It was to them that Chopin wrote his most interesting and self-revealing letters.

We shall meet them and hear of them often in the course of this narrative, for their friendship with the musician was severed only by death.

It will therefore suffice to say here that Titus Woyciechowski, who had been Chopin's school-fellow, lived, at the period of the latter's life we have now reached, on his family estates, and that John Matuszynski was then studying medicine in Warsaw.
In his letter of December 27, 1828, Chopin makes some allusions to the Warsaw theatres.

The French company had played Rataplan, and at the National Theatre they had performed a comedy of Fredro's, Weber's Preciosa, and Auber's Macon.

A musical event whichmust have interested Chopin much more than the performances of the two last-mentioned works took place in the first half of the year 1829--namely, Hummel's appearance in Warsaw.
