All the music we know that's popular is actually commonly shared music that takes things that are similar about all of us.

The Beatles realized that what they were making in the studio could never be performed. And they had already given up on performing because there were too many screaming fans and they were playing in larger and larger venues so they couldn't even hear what they were playing, it just wasn't any fun any more.

I'd studied piano first and switched over to cello when I was about seven. I played mostly chamber and solo classical music. I got really involved with rock music when I was a teenager. I wired up my cello.

I went to the University of California, Santa Cruz for a year, which turned out to be a really vibrant, very intensive intellectual atmosphere where you could do a lot of aspect of music without it being a conservatory. And that's why I went there.

A piano is a machine, but you've got ivory and there's weight behind the keys and you have this really - you feel the resonance in the instrument, you feel the vibration in the pedal. I mean, these a still very crude.

You have to train your mind and your ears, but they're more like athletic skills. So, part of music you just have to learn those things or you can't practice the art.

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.
