With devices my technique is always to hide the handbook in the drawer until I've played with it for a while. The handbook always tells you what it does, and you can be quite sure that if it's a complex device it can do at least fifteen other things that weren't predicted in the handbook, or that they didn't consider desirable. It's normally those other things that interest me.

Of all the things you can now do, which do you choose to do?

People who are very confident in themselves aren't hurt by criticism. They make use of it.

Any constraint is part of the skeleton that you build the composition on - including your own incompetence.

Once I started working with generative music in the 1970s, I was flirting with ideas of making a kind of endless music - not like a record that you'd put on, which would play for a while and finish.

I think the other thing that's important is getting to a place, which very, very rarely happens with improvising groups, where somebody can decide not to play for a while. You watch any group of musicians improvising together and they nearly all play nearly all the time. In fact I often say that the biggest difference between classical music and everything else is that classical musicians sometimes shut up because they're told to, because the score tells them to. Whereas any music that's sort of based on folk or jazz, everybody plays all the time.

For me it's always contingent on getting a sound-the sound always suggests what kind of melody it should be. So it's always sound first and then the line afterwards.
