        http://www.execpc.com/~wsannis/ratio.html is a good starting
point for Just Intonation via Python, if I do say so myself. :)

        See http://www.dnai.com/~jinetwk/ for links to mode detailed
descriptions of the various tuning systems available.

        Equal tempered scales are a matter of simply finding roots.
the where s = 12th root of 2, s^n is the nth step of the normal 12-tet
scale we all know and love in most European-derived musics
(remembering that a frequency doubled is the octave).  So, if for some
reason you want a 22-tone equal tempered scale, just find the 22nd
root of 2.
