I would love to see this but don’t want to run the code. Could you link a video? I understand if you have to omit or mangle sound to avoid strikes.

Found his web page with some basic demos/vids. Had the same curiosity. https://jimishol.github.io/post/tonality/ https://jimishol.github.io/post/tonality/

  Thanks for digging that up! That blog post covers the early "from scratch" version—essentially a mind experiment. Interestingly, Dmitri Tymoczko arrives at a similar prism structure (Figure 14b) in his paper "The Generalized Tonnetz" ( https://read.dukeupress.edu/journal-of-music-theory/article/56/1/1/14424/The-Generalized-Tonnetz https://read.dukeupress.edu/journal-of-music-theory/article/... ). I reached a similar shape (Figure 11 in my pdf: https://jimishol.github.io/thoughts_on_harmony_en.pdf#page=29 https://jimishol.github.io/thoughts_on_harmony_en.pdf#page=2... ), but the specific, even arbitrary, twisting I used to realize the torus topology gives it a unique advantage: it immediately reveals the "hinge note" of a scale. I discuss that specific geometric comparison here: https://github.com/jimishol/cholidean-harmony-structure/discussions/12 https://github.com/jimishol/cholidean-harmony-structure/disc... The new documentation in this repo ( https://github.com/jimishol/cholidean-harmony-structure https://github.com/jimishol/cholidean-harmony-structure ) represents the mature "Umbilic-Surface Grammar" that explains why those shapes happen.

Apologies for the delay! You don't need to run the code to see the theory in action. I have included a visualization GIF in the main README. While the demos in the installation section are short, they do contain audio-visual examples. Direct link to the README: https://github.com/jimishol/cholidean-harmony-structure/blob/main/README.md https://github.com/jimishol/cholidean-harmony-structure/blob...
