johannes quint has an example of shepard tones in his course
materials. the s.t. are the most obvious spiral sound i can think of
off hand.
it would be trivial to rewrite the code for fm-violin

Hi,
This is a rather conceptual question, but I am interested in trying
to somehow represent the concept of a spiral in CLM. I figure this
would probably involve the golden ratio and fibonacci series
number, but I am stuck as to how to begin and how this "sound
spiral" would actually sound. This corresponds to my earlier
question about just intonation, because according to Alain Danielou
( in his book Music and the Power of Sound), the circle of fifths
originated from a "spiral of fifths", which was modified by either
slightly sharping or flatting certain notes to get equal
temperament for the pianoforte; just intonation, according to him,
was a truer representation of the "pure" musical intervals that
occurred in nature, so to speak. I guess my goal here is try to
somehow represent the concept of the spiral both melodically and
rhythmically in CLM since this pattern seems to inform so much of
how of and why things evolve the way they do. This could obviously
get very complicated and beyond the timeframe I have to complete my
project, so I'm hoping for short but potent bits of information
here. Sorry to lay such a huge question on what is generally a
fairly practical discussion list, but I need to find ways of
narrowing the focus of this idea soon.
Thanks much,
JHD
