»How can there be any bad music? All music is from heaven and if there is anything bad in it, I put it there.«

»My God! What has sound got to do with music.«

»Beauty in music is too often confused with something that lets the ears lie back in an easy chair. Many sounds that we are used to, do not bother us, and for that reason, we are inclined to call them beautiful.«

»Unser größter Lehrmeister ist der Ton.«

»Die Musik ist nicht in den Noten, sie ist im Musiker.«
