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.

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.

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 was hired for a really excellent academic job early in my life; I was twenty-five when I started at Princeton and I got tenure early on. I really didn't deserve this; I just happened to be in the right place at the right time.

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.

I didn't want my music to be seen as examples of an electronic culture; I just wanted them to be thought of as pieces of music.

There are, however, composers whose music can only be heard in a chromatic sense. George Perle, for example, wrote pieces that you might think of as leaning in a tonal direction but it's very hard to register a pitch as, say, the sixth degree of a scale, whereas in much of my music I think that's often relatively easy to do.
