Scholarly discussion of the music of John Cage.

[David Bellows <>]

Hey Rob, thank you for the additional details! I think it is a safe assumption then that Cage used the 3 coin method at Bell Labs as well since it is what he used before and afterwards. 

I was having a conversation with a person and had assumed, based on my slight knowledge of the I Ching, that Cage had used the 3 coin method but then I realized that I didn't know this for a fact which is why I brought it up here. I'm glad that my assumption appears to match well with reality.

Thanks again,

Dave Bellows

He did use the three-coin method before working on HPSCHD, when he used the computers at Illinois to generate hexagram numbers. That iteration, however, had some flaw that he discovered while working on Empty Words. That's where the story ends for me. He may have then gone to Bell Labs (this would make some sense given the Experiments in Arts and Technology where Variations VII) was premiered. I believe David Revill teells a story that Cage hired people to toss coins for him (as well as asking friends to do it) when he was finishing Music of Changes.

I apologize if I have some of these details wrong. I'm not at home so can't consult my library.

All best,

Rob

David,

ic is a simulation of the three coin tossing method. Three coins, tossed six times, producing changing or unchanging broken or unbroken lines, rendering one of 64 possible original hexagrams, and possibly an additional changing hexagram also one of 64.

You can use ic, and learn more about how it works (read “How”) here: https://anarchicharmony.org/IChing/index.html

It’s the method I used before working with John, and before I “put it on the computer” (JC phrase!), i.e. when I did it by hand for my own purposes, divinational or compositional. (BTW, I consulted the I Ching about whether I should move to New York and offer to work with John, one of the more momentous questions I ever asked it. The reply was convincing.)

When I arrived (1980) he was using printouts from a program written at Bell Labs. I don’t know what method that program simulated.

Others on this list will know better than I what method he used in the early days before any computers were involved, but I always assumed (or perhaps heard in passing) that it was the three coin method.

Peace (war is obsolete)
