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.

You get up early in the morning and you work all day. That’s the only secret.

The generation of composers that are just preceded me, people like [Karlheinz] Stockhausen, [Pierre] Boulez, and, well, [John] Cage for that matter,[Morton] Feldman ... That was a kind of experimental music that was very isolated. It had no real public.

So the real drama for me is balancing live performances and writing, and one of the ways I balance it is I write in hotel rooms. That's not exactly balancing. Actually, writing in hotel rooms means that I'm refusing to deal with the problem.

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.

What I've noticed is that people who love what they do, regardless of what that might be, tend to live longer.

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.
