One way to look at them is to consider that you can generate them by repeated rescale/replace cycles. It's pretty obvious how to use this rhythmically--generate e.g. a drum pattern, make a sped-up copy of the pattern, and replace each note of the original one with one of the sped-up copies. Lather, rinse, repeat. You could make things even "fractaler" by applying the same method to pitch, if you don't mind jettisoning the twelve-note-per-octave chromatic scale. Play a chord. Pick one note as the root. Note the ratios of the frequencies of all the other notes to that of the root. Scale the ratios by a number much less than one, generating a new "chord" whose pitches are likely much closer together than a half step. Replace each note in the original chord with a copy of the "chord," pitch-shifted to the original root. Repeat until traumatized. Something like this would be much easier to do with, say, csound than in real time with with a fretted instrument. And, like a lot of other applications of mathematics to music, I'm guessing that in practice this is a lot less musically useful than it sounds. Brian
