I don't think of my music as being about something.

I've had a lot of fun writing percussion music. It feels quite similar to writing computer music. But I found myself in the role of choreographer in a way, worrying about physical movement and such.

I came to what I think of as the critical problem: the aging process of a piece of music. I noticed in the '70s that pieces I wrote would sound great the first time I listened to them and then on repeated hearings they sounded older and older until what seemed exciting and vibrant on first listening became stale.

When you have performers, there's the uniqueness of live performance and what performers do in concerts.

I don't think of my music as being about something.

I can't say that there's a common practice that has to do with pitch language or with the way pieces are put together because today, anything is fair game. As far as I'm concerned, my own common practice is a piece that engages the attention of listeners from beginning to end, and doesn't rely on or expect the listener to zone out.

Even today, I notice that some of my pieces are explicitly tonal; there are actually tonics and dominants. And then there are pieces that are not tonal. I tend to think that there's a dichotomy that has to do with the way pitches are structured.
