Rationality is what we do to organize the world, to make it possible to predict. Art is the rehearsal for the inapplicability and failure of that process.

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.

In fact, quite a lot of what I do has to do with sound texture, and, you can't notate that. You can't notate the sound of "St. Elmo's Fire." There's no way of writing that down. That's because musical notation arose at a time when sound textures were limited. If you said violins and woodwind that defined the sound texture; if I say synthesizer and guitar it means nothing - you're talking about 28,000 variables.

People always focus on people like me who use synthesizers, right, which are explicitly electronic and therefore obvious. "Ah, yes, that's electronic music." But they don't realize that so is the concept of actually taking a piece of extant music and literally re-collaging it, taking chunks out and changing the dynamics radically and creating new rhythmic structures with echo and all that. That's real electronic music, as far as I'm concerned.

When you sing with a group of people, you learn how to subsume yourself into a group consciousness because a capella singing is all about the immersion of the self into the community. That's one of the great feelings - to stop being me for a little while and to become us. That way lies empathy, the great social virtue.

When you look back on a historical period of music, it seems so obvious to you what the characteristics of it are, but they're not obvious at the time. So, when I look back at my own work, I could easily write a very convincing sort of account of it that made it look like I had planned it all out from day one and that this led logically to that and then I did this and then that followed quite naturally from that. But that's not how it felt.

I often say to people that producing is the best paid form of cowardice. When you produce things you almost always get credit, if it's a good record, but you hardly ever get the blame if it's not! You don't really take responsibility for your work.
