Traditions are imploding and exploding everywhere - everything is coming together, for better or worse, and we can no longer pretend were all living in different worlds because were on different continents.

What you hear depends on how you focus your ear. We're not talking about inventing a new language, but rather inventing new perceptions of existing languages.

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.

Satyagraha is an opera which I wrote for the Netherlands Opera, so it uses an orchestra of around fifty, a chorus of forty, and there are about seven soloists. The opera ... Satyagraha means truthful, so it was a name [Mahatma] Gandhi used to describe his civil disobedience movement.

What came to me as a revelation was the use of rhythm in developing an overall structure in music.

I consider the first 20 performances just learning the piece. Think about it this way: If you think about a pianist who plays a Schubert sonata through his whole lifetime - if you listen to Rubenstein or Horowitz playing their repertoire later in their life, you understand the richness with which they play that music, and how differently they must have played it when they were younger.

I was a regular kind of academic music student. I was at Juilliard. I had to study all the contemporary music of the time, and changing that language very radically was just a sign or a signal that I was going to try to do something very different. I find that that's what I feel closest to. I found no real inner response in me in a non-tonal language.
