Does your artist friend have any idea what base 12 means?
The chromatic scale is based on one twelfth powers of two, i.e., if the frequency of a note in the scale is f(n), then the frequency of the next note is given by
f(n+1) = f(n) * 2^(1/12)
so by the time you go all 12 notes in an octave you have doubled the frequency. There is nothing here involving base 12 or pi.
He's a friend of a friend. I don't know what he knows, but I'll forward this to MY friend. Thanks.
