A mouse and a keyboard is not a good performance instrument.

Walk so silently that the bottoms of your feet become ears

There are these sounds that come from outside that work really well if you're listening. If you're not listening, if you're blocking them out, then you don't get it. You don't get the merger of what the players are doing with everything, listening to everything.

That's software in the States that I helped to develop. It enables people with disabilities to improvise.

I felt a challenge to compose music. That's where my challenge was, for the most part.

Something that I did, and I developed out of that sonic meditations, which were pieces that I composed in the '70s that now are very well-known and used in many classrooms all over the world, but at the time were outrageous.

I wrote my sonic meditations and started using them with students. I took a bunch of UCSD students out to Joshua Tree and we did the sonic meditations on the boulders.
