This reminded me of a spiral/helix of fifths music theory poster I had twenty years ago. I can't find it now, but in my research, this came up: Music Through Computation, Carl McTague, 2003 International Mathematica Symposium https://www.mctague.org/carl/music/computer/talks/music-talk-2003/Music.ppt.pdf https://www.mctague.org/carl/music/computer/talks/music-talk... And it does indeed have a nice picture for "Helix of Fifths" that is a dry black and white sketch of what was on that poster.
