I never thought that I would write orchestra music, but in fact I did write a group of orchestra pieces.

Sometimes I imagine that there's a binary division going on in contemporary practice that has to do with chromatic versus diatonic. I notice that I tend to listen in a diatonic sense, that I register a pitch as a member of a diatonic scale, even in a non-tonal context.

I found myself recycling ideas and I saw that I had to invent reasons to compose a piece rather than start from some exciting idea.

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.

I came up in the '60s; that was a time when there was a revolution going on in music. Stravinsky had become a twelve-tone composer; even Aaron Copland was writing twelve-tone pieces at that time!

Very often, when you're listening to a piece for the first time, you're listening through a model of other pieces that you know. At a certain point, a piece becomes idiosyncratic and you start to understand it on its own terms.

With a piece of classical music by Haydn, Mozart, or Beethoven, on first listening I'm referencing it with other pieces by them that I know. I think that most people do this - they listen to pieces through the filter of pieces they already know.
