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

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.

Deep listening is experiencing heightened awareness or expanded awareness of sound and of silence, of quiet, and of sounding - making sounds.

Now, I have about twenty per hand and can change the number of delays, change different parameters, the delays to the modulations and so forth. I developed the EIS over the time period that I was just talking about [1991].

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.

It's going to take about a year or two for the transfer to be completed. We have a certification program so professionals can teach deep listening.

First of all I had to teach myself how to use the studio because there wasn't any classes in electronic music. So I'd stay there all night and leave in the morning, observe the sun rise and have a lot of different kinds of sounds in my mind. But it was a quest, it was a search. It was research, it was learning.
