»Music is work.«

»When we separate music from life we get art.«

»Let no one imagine that in owning a record he has music. The very practice of music is a celebration that we own nothing.«

»It is better to make a piece of music than to perform one, better to perform one than to listen to one, better to listen to one than to misuse it as a means of distraction, entertainment, or acquisitiuon of ›culture‹.«

»Which is more musical: a truck passing by a factory or a truck passing by a music school?«

»When you make music you are acting as a philosopher. You can either do that consciously or you can do it unconsciously, but you're doing it.«

»The material of music is sound and silence. Integrating these is composing.«

»Die Musik, mit der ich mich beschäftige, muß nicht unbedingt Musik genannt werden.«
