John Coltrane's Music & Geometry. Note: this article is a "work in progress".
There is a lot more to "figure out" about Coltrane's work, so the content of this article might change. In this article I will use and refer to the "Coltrane Tone circle". John Coltrane Draws a Picture Illustrating the Mathematics of Music. Physicist and saxophonist Stephon Alexander has argued in his many public lectures and his book The Jazz of Physics that Albert Einstein and John Coltrane had quite a lot in common.
