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.

I started thinking, my gosh, all this sophisticated software for measuring how Yo-Yo plays, and how he moves and this technique of the bow, I should be able to use similar techniques for measuring the way anybody moves, and so somebody who is not a professional or a trained musician, I should be able to make a musical environment for them.

Nobody talks about music as having intrinsic meaning, how it engages the mind.

There's just an incredibly rich and interesting relationship between our listening to music and the way our minds engage.

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.

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.

I love the cello, I love the physical sense of an instrument that's about the size of your body that vibrates enough that even if you play an open string, you feel it.
