John Cage

“At one point, Cage rose up from below the stage on a hydraulic platform playing the piano. People were furious. I was flabbergasted. He used a radio as one of his instruments, too. At one moment he turned it on and got the voice of the Pope asking for peace in the world. It was a wonderful moment. One man strode down the aisle with a cane. He hit the piano and said, “Now I am a composer!” I guess you could say that concert blew my mind. I stopped writing music for a year.” Alvin Lucier, Music 109

From John Cage and Richard Kostelanetz: A Conversation about Radio
How did you develop in the early fifties the notion of using radio as a musical instrument?
There was a tendency through the whole twentieth century, from the Futurists on, to use noises, anything that produced sound, as a musical instrument. It wasn’t really a leap on my part; it was, rather, simply opening my ears to what was in the air.
Do you remember your thinking at that time?
Yes, my thinking was that I didn’t like the radio and that I would be able to like it if I used it in my work. That’s the same kind of thinking that we ascribe to the cave dwellers in their drawings of the frightening animals on the walls—that through making the pictures of them that they would come to terms with them.
Now why did you choose twelve radios, rather than just one, for Imaginary Landscape No. 4?
There’re so many possible answers; I don’t remember which one was in my head. One is the twelve tones of the octave, and the other is the twelve disciples, and so on. It seemed like a reasonable number.
Didn’t you have two operators for each radio?
Right. One controlled kilocycles and the other controlled the tone control and the volume.
Were those twenty-four radio-performers musicians?
Yes, they were. They could all read notes, and there was a conductor who was beating 4/4 time.
Who was he?
I was doing it.
My recollection is that there was something special about what time of day this performance was.
The first performance had almost no sound in it. Two friends of mine at the time, Henry Cowell and Virgil Thomson, both attributed the absence of sound to the fact that it was late at night—it was nearly midnight. However, I knew that the piece was essentially quiet through the use of chance operations and that there was very little sound in it, even in broad daylight, so to speak. The volume levels would always be very low.
What about your other works for radio at that time.
Radio Music [1956] and Speech [1955] “for five radios and newsreader. They’re slightly different, but the radio piece was written more or less to please the people who were disturbed over the Imaginary Landscape No. 4 because it was so quiet. I forget what I did, but it can be played so as to be loud
Your catalogue of twenty years ago says that in Radio Music “durations of tunings are free,but each is to be expressed by maximum amplitude.
It does? Well then it’s obvious that that’s what it was. If people wanted radios to be loud, that was the piece to play.
How did your writing these pieces change your attitude to radio, at least in your persona life?
JC: It made it possible for me to listen to radio with great interest, no matter what it was doing.
And what did you listen to then?
Anything that I happened to hear. I didn’t myself turn on a radio to listen to it; but when I was going through the streets or when a neighbour was playing the radio, and so forth, I listened as though I were listening to a musical instrument.
Did radio become a favourite musical instrument?
Almost as favoured by me as the sounds of traffic.

John Cage & Don Buchla

“Well, [David] Tudor was one of my first customers. Cage and Tudor visited me at my studio in Berkeley and I remember that occasion. My studio at that time was ten feet wide and I worked out on the sidewalk. It was so crowded in there we hauled the workbench out on the sidewalk on good days and set up my oscilloscope and worked out there. Cage came by and for voltage control I had hooked up my keyboard to an FM module that I’d built, a little module that was an FM receiver and I could play stations on it because I had one of the first varactor tuned FMs. Cage, as you can imagine was, just enormously interested in the fact that I could tune each key to a station and then proceeded to play the radio. I had already met Cage while putting together some of his pieces that involved perhaps multiple radios, phonographs and so on”
