I think a double bass for me would be too much effort. But the cello, you're really engaged and the sound is kind of right here. So, it feels like being merged, married to an instrument.

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.

Music seems to stimulate more parts of our mind than almost every other activity. It combines more parts of our minds. It synchronizes our minds. It allows people in groups to do a non-verbal immediate activity together.

My work on hyper instruments started with simple instruments, like the piano.

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

I think it's maybe because Sergeant Pepper's came out when I was about 13 or 14 and that was a pretty impressionable age, and it was such a kind of radical period. But that period of the Beatles really had a big influence on me and I think are directly related to hyperinstruments.

The one obvious thing is that the devices are so good now that you can also see their limitations extremely well.
