But the difference between the little pieces and the big pieces - I'm not actually sure which are the little pieces. With some of the big pieces, it's a lot of musical running around, whereas the little pieces, you can say everything you want to say.

I've been working in theater, really, since about 1965. I started working with the Mabou Mines about then, and in a way I've always worked in the theater, but it's never been a main part of my work. And it wasn't until Einstein that I kind of shifted into high gear with theater, working with Bob, with Bob Wilson. And since then I find it a very attractive form to work in. It's just an extension of my work.

I always knew what I wanted to do and I did it.

Finally, ultimately, you write music for yourself. I mean, I need a public, I need people to play, I need everything else. I'm not working in isolation. But finally the man that writes the music is alone. And I have to respond to those criteria which are almost like inner needs or inner responses.

I find that people can’t find you. It’s kind of quiet. When I go to a city, I can almost always get a piano if I need one. So there’s something nice about being on the road and focusing on something you want to do.

I shift between mediums very frequently. Instead of taking a break from writing, I just write in a different medium or in a different way or for a different purpose, so that I don't actually stop writing - I just go to something else. Like going from a big symphony to a piano piece is great and very refreshing, I find. And then going from that to a big concerto, and then having to go out and play.

Theatrical times are different from concert times, to put it simply. Taking a figure like [Mahatma] Gandhi and setting him on a stage requires thinking about what theater is about and what the whole experience is about and what we're trying to communicate in that way, so you get into certain less abstract considerations.
