"If you want to know about the Sixties, play the music of The Beatles."

“For me, the most important thing is the element of chance that is built into a live performance. The very great drawback of recorded sound is the fact that it is always the same. No matter how wonderful a recording is, I know that I couldn't live with it--even of my own music--with the same nuances forever.”

“I hope my recordings of my own works won't inhibit other people's performances. The brutal fact is that one doesn't always get the exact tempo one wants, although one improves with experience.”

“I object to background music no matter how good it is. Composers want people to listen to their music, they don't want them doing something else while their music is on. I'd like to get the guy who sold all those big businessmen the idea of putting music in the elevators, for he was really clever. What on earth good does it do anybody to hear those four or eight bars while going up a few flights.”

“Somehow, suddenly, a musical idea occurs to you; either a whole phrase, or three notes, or a series of chords, something that seems pregnant with possibilities for development. Once you have the kinds of ideas that fascinate you, you're no longer in a position to decide the nature of the animal. It's going to take its essence from the musical ideas that occur to you....Some musical ideas are too short, they don't seem long enough to carry you through ten minutes of music, so you have to start searching about for other ideas; contrasting ones that seem to fit with the original ones.”

“I adore extravagance but I abhor waste.”

“The composer who is frightened of losing his artistic integrity through contact with a mass audience is no longer aware of the meaning of the word art.”
