Rotating polygons on the circle of fifths

[Donny Hinson]

Yeah, I know this sounds pretty weird. But those who like both geometry and music (there might be one or two out there) may find it interesting...or boring.

Thanks for posting this, I land somewhere in between…
First thing that popped into my head was the song from The Blind Faith album from the late sixties, the cut titled “Do What You Like”
I think I’ll go back over sixty years when I first started playing 6 string & keys which is playing by “ear”!
Still good stuff in my view, music theory is important to discuss at times.
Someone once said to me years ago…”learn as much as you can, then forget about it and just play”
Interesting, I’ll need to digest this further though.

Thanks for posting that, Donny.
I find the connections between music and mathematics interesting. The pentagon was a surprise!

The equilateral triangle is where Coltrane’s “Giant Steps” came from. He certainly had a thing for musical geometry.

I think Buddy Emmons may have been similarly intrigued. Probably most great musicians have also been great mathematicians, of a sort.
