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.

I have a variety of ways that I make music, but I'm working with the Thingamajigs in a particular way, which is: They are bringing to me their performance skills and their unusual instruments, which I'm relishing. They're really beautiful. The other thing is improvisation - these players improvise and they do it very beautifully, as a matter of fact.

Before that, an 8-bit recording was pixelated; it was really bad. It didn't serve what I was doing, which was recording live sound and delaying it and feeding it back. This is essentially what the EIS system is: a bunch of delays.

The students were missing out a lot in their ensemble playing because they weren't listening to each other or the environment.

I'll just say that I made my own explorations of tone by listening to a tone for a long time until I began to understand what my sensations were, what my mind was doing with tone.

I had invented my own system, my own way of making electronic music at the San Francisco Tape Music Centre, and I was using what is now referred to as a classical electronic music studio, consisting of tube oscillators and patch bays. There were no mixers or synthesizers. So I managed to figure out how to make the oscillators sing. I used a tape delay system using two tape recorders and stringing the tape between the two tape machines and being able to configure the tracks coming back in different ways.
