There is so much gibberish and mystical nonsense in this thread, it perhaps deserves the BS label!

"Since I'm talking about the Circle of 5ths, it should be painfully obvious that I have no interest in these other tunings"

You may think you know everything, and may have read Wiki - but this statement reveals that you have no understanding! If you need to ask WHY, that proves you know naught!

You can't draw the 7-pointed star from it. That's significant because the circle unites music and geometry.

You have a love of mysticism - but musicians do not need mystical gibberish to make nice noises. Some merely need to open their mouth, but some should perhaps keep it shut.

"A couple of references were made to "divide the circle into twelve equal arcs." There are 13 notes in the chromatic scale so the division must be triskadecate, not duodecate."

John - I thought you knew about computing science - you have committed the 'fencepost error' - 13 notes (posts) have 12 intervals (panels) in a straight line, but the same number ()12 in a circular fence! AND by convention, the octave is the same as the fundamental.

Bloody hell, I'm off to get more peanuts!
