it's important as a composer to sit in silence and imagine these complex musical worlds in your head, but it's also a wonderful experience to touch your music and to hear it and hear it in the room with you and to say, you can't have an entire orchestra there, but you'd kind of like to have the orchestra there.

Over my career, I'd say the last 25 years; we've gone from music and computer being for 10 people in the world to having personal computers, to now being able to do amazing things on your iPhone, or with Rock Band. So, right now there's enormous capability with technology in our devices that everybody has access to.

Why does every society seem to want to make music when it often seems like kind of a frill.

I love silence. And one of the paradoxes about the way I live and also about my work is that definitely one of the reasons I went into music, and especially into composing is that I love setting up an environment where I can be by myself for long periods of time and have everything as quiet as possible, either to think about sound, or to think about ideas, or just to focus on things that are important to me.

The way I listen to music goes in waves depending on a lot of things. How busy I am, if I'm in between composition projects, if I'm starting a new project. So, the only time I listen to the radio for music is with my daughter's when I'm driving them to school, or driving them somewhere.

There were a lot of things happen in the mid-'80's that all of a sudden made it possible to do a lot of very quick interactive music.

I like the idea of imagining a sound and feeling a sound and then having it come out through your body, through an instrument. That's an important way to make music.
