"It is necessary to practice diligently, for mastery comes only through hard work."

"I have to put up with a great deal of annoyance and envy, and consequently I am forced to live in almost constant vexation."

"I play the notes in order, and the music comes out."

"I often think of new compositions while walking."

"The aim and final end of all music should be none other than the glory of God and the refreshment of the soul."
