— Walter Pater
I really don’t know much about music theory, but I know I like this chromatic “circle” with solmization center.
Also, if you count out seven triangles clockwise around the rim starting from C you get G, D, A, E, B, F#, etc., which is the Circle of Fifths for chords. (But you get that with any chromatic circle.)
And I imagine if you go counter-clockwise you get the Circle of Fourths, which is important for Jazz chords!
