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

All the way from the first thing that I can remember, like our Victrola - a wind-up record player - and my grandfather's crystal radio, and my father's shortwave radio.

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 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.

After a long section of the glass playing, you'll hear an instrumental sound emerge from some undisclosed location. There'll be a lot of mystery about the sound, I think.

Deep Listening Institute is dissolving and is now the Center for Deep Listening at Rensselaer Polytechnic Institute (RPI). The legacy of the twenty or thirty years that we've been operating is now transferred to RPI.

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.
