Great list of books on music and mathematics. It's an endlessly fascinating subject that appeals to the intellect and the heart. I remember years ago, reading Godfried Toussaint's paper, "The Euclidean Algorithm Generates Traditional Musical Rhythms". [LINK] (PDF) Following the trail, I was glad to find he wrote a whole book, The Geometry of Musical Rhythm, where the article forms the basis of a chapter. It's one of my favorite books I keep returning to re-read different parts. I hadn't seen "Exploring Musical Spaces", looking forward to reading it. Dmitri Tymoczko's book is wonderful too, A Geometry of Music: Harmony and Counterpoint in the Extended Common Practice. Rich with ideas and insights, I like how he tells the history and development of Western music theory. Oh I just learned from the author's website that he has a new book released. > I have just finished a second book, Tonality: An Owner's Manual, that proposes a new, hierarchical, and geometrical model of musical stucture. > One interesting outgrowth is the musical programming language arca. This line of thinking has also led me to contemplate a third book about category theory and music. [LINK] --- This video of your live performance setup as a one-man band. Amazing. this video
The generated [Latin Jazz with small band with acc. guitar]( [LINK] ) sounds awesome, like an upscaled version of the original. [Now I see what you mean by playing them all live at once.]( this video ) Being able to scrub to the middle of songs would be nice, it's too much effort for 99% of visitors to figure out that we need to open links in a new tab to get to the raw, scrubbable mp3.
Korg microkey is great; I have stacked two of them on my other keyboard and use it even for live setups without any issue so far; see e.g. this video or [LINK] .
