„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.“
— Frédéric Chopin
His letter to Tytus Woyciechowski in Poturzyn. Paris, 12 December 1831.
