Have you heard of the architect Christopher Alexander? His life's work seems to be close to what you are describing. I'd highly recommend the 4 volume series 'The Nature of Order.'

I've always felt that there is a whole other math based explanation to art and music, that may even bridge the two, hiding in plain site. Alexander is the only person I've read who has come close to describing this math.

Any body else here know what I mean?

Not exactly what you are looking for but... visually speaking, Paul Klee's notebooks are incredible resources and online as PDFs.

I'm reading "A Pattern Language" right now and it's pretty revelatory. It certainly suggests that structural properties of natural languages are prevalent throughout culturally-transmitted behaviors

I'm really looking forward to checking out these books, thanks for recommending!

My favorite Math/Music text is "The Harmonic Experience", by W.A. Mathieu.

Yes, I've read them all. Truly changed the way I look at and think about things in all sorts of contexts.
