I had to cope with attitudes that were not supportive all along. I mean, you still have that.

Maybe I'll start from the initial idea, what motivated me to do that. In 1953, I had access to a tape recorder. Tape recorders were not widely available. There was no cassette tape back then. It was a Sears Roebuck tape machine. I put a microphone in the window and recorded the ambience.

Listening is selecting and interpreting and acting and making decisions.

You invent things like algorithms to take care of some of the changes you want to make. The changes aren't detectable. There's all kinds of things happening as I play.

[My interest in music] is from my mother and my grandmother, who were pianists, and they taught.

The sound that I play is delayed, it's modified, and it's modulated. It's an intelligent system; it's happening now.

I got very interested in attention and awareness and how to achieve certain states through understanding this.
