Composition is a way of living out your philosophy and calling it art.

I always use the same guitar; I got this guitar years and years ago for nine pounds. It's still got the same strings on it.

You know that in order to copyright material somebody has to write it down for you. Any piece of recorded material has to be scored in order for it to be copyrighted. I've seen the scores of my things and they don't resemble the music in any way. If you give them to somebody who has never heard the music and say, "What does this sound like to you?" they'll play you something that has no relationship with the music it derives from. Notation simply isn't adequate.

In the 19th century, a lot of people were against outlawing child labour, because to do so would be against the very foundations of a free market economy: 'These children want to work, these people want to employ them... what is your problem? It's not as if anyone has kidnapped them...'

The artists of the past who impressed me were the ones who really focused their work.

In the 1960s, people were trying to get away from the pop song format. Tracks were getting longer, or much, much shorter.

A lot of the so-called systems composers have this thing that the system is always right. You don't fiddle with it at all. Well, I don't think that. I think the system is as right as you judge it to be. If for some reason you don't like a bit of it you must trust your intuition on that. I don't take a doctrinaire approach to systems.
