In the beginning we were making tape music, meaning, we were making music on tape.

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

It was around the end of the '60s, when I began to compose sonic meditations. Before that I was doing a lot of reflecting on myself, and listening to long tones.

Everybody improvises their way through every day. And so I do that with music.

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].

Deep Listening is listening to everything all the time, and reminding yourself when you're not. But going below the surface too, it's an active process. It's not passive. I mean hearing is passive in that soundwaves hinge upon the eardrum. You can do both. You can focus and be receptive to your surroundings. If you're tuned out, then you're not in contact with your surroundings. You have to process what you hear. Hearing and listening are not the same thing.

Radio broadcasting was only 25 years old when I was born in 1932.
