Sometimes I can only groan, and suffer, and pour out my despair at the piano! - Frédéric Chopin

I have met Rossini, Cherubini, Baillot, etc.—also Kalkbrenner. You would not believe how curious I was about Herz, Liszt, Hiller, etc. — They are all zero beside Kalkbrenner. I confess that I have played like Herz, but would wish to play like Kalkbrenner. If Paganini is perfection, Kalkbrenner is his equal, but in quite another style.

I could express my feelings more easily if they could be put into the notes of music, but as the very best concert would not cover my affection for you, dear daddy, I must use the simple words of my heart, to lay before you my utmost gratitude and filial affection

[...] mam mój ideał, któremu wiernie, nie mówiąc z nim już pół roku, służę, który mi się śni, na którego pamiątkę stanęło adagio od mojego koncertu, który mi inspirował tego walczyka dziś rano, co ci posyłam.
