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.

The experimentation that I do has a lot to do with tunes and pitches and ways that melodies are put together.

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.

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 don't think there's something that you have to 'get' with my music. It tends toward the dramatic side rather than the narrative.

It's always a thrill for me to see new versions of my pieces on YouTube.
