My first tape piece was made with that Sears Roebuck recorder. I modified sound using cardboard tubes with a microphone in the end to filter the sound. I had a wooden apple box with a Piezo [contact] mic and little objects that I could amplify on the box. I used the bathtub for reverberation.

I think that this performance with the Thingamajigs is going to be an exploration of the acoustic space and particularly the vertical space, which we don't think about so much.

When I composed the first sonic meditation, I realized that I was composing the direction of attention.

I have a commission to do a piece in a place in California, Oliver Ranch, which has an eight-storey structure called The Tower designed by the visual artist Ann Hamilton.

I feel that students always learn more from each other than they do from their professor. They learn by doing and not by trying to soak up information from one person.

That was at the Michigan Womyn's Music Festival in about 1989. There were 6,000 women there, and they were out in a meadow, and I offered the tuning meditation and they did it.

That change happened about 1991. It was not possible to transfer the Expanded Instrument System to the computer until then, when 16-bit recording became available.
