What a beautiful write up and description. In naive pursuit of related ideas with less of a grounding in music theory, I use something called a "fractal sequencer," in my modular rack which is like a normal linear sequencer you would find on a synth, but with mutation, recursion, and iteration. This idea of subperficial and deep structure the author talks about, and a fractal tree with trunks and branches, are closely related, and it maps very well to this description. I wanted to see if I could use fractals to generate consonant melodies that were indistinguishable from pop music using patterns called 1/f noise. The idea was I wanted to see whether by just adding musical entropy in the form of 1/f noise to a repetitive pattern if it would be interpreted as persuasively "new" and "interesting," to our brains. My own result is just a rough live take from messing around with it ( https://soundcloud.com/n-gram-music/beatrice https://soundcloud.com/n-gram-music/beatrice ) but if you want to know what a consonant autogenerated pop fractal sounds like, the upper solo line over top of the three note melody is produced by on a Qu-Bit Bloom sequencer iterating over a bunch of 4ths and 5ths and driving its own oscillator. Similarily, I recorded one with with a more early 80s electronica tone that is less fun, but more atmosphereic in iterating through the space of possible melodies (https://soundcloud.com/n-gram-music/decade https://soundcloud.com/n-gram-music/decade) This ch0pi1n python library looks supremely interesting, as when we listen to music, we're really expressing structures and shapes in consonance and dissonance with each other where each elaborates facets of the others. These are if not functions, at least algorithms composed over types. The author's description of these is just the right level for deriving and applying a logical architecture without diving into some bonkers numerological gematria. The post is a beautiful way of thinking about these forms. I look forward to revisiting it and playing with the library.
