howdy all...
just a quick question. i just read david's summary of
the "auric time scale and the mayan factor" paper.
i read the actual paper when david first posted about
it, and got the gist of it, but david's summary was
alot easier to grasp.
david says:
"...the phi ratio, which has a value of 1.6180339. this
ratio can be easily seen in the relationships between
common 'diatonic' musical frequencies as well as..."
my question is...where exactly is the phi ratio easily
seen in the diatonic scale?
the only things close to it are the perfect 5th (3/2 or 1.5),
the minor6th (~1.5892) and major6th (~1.7838) (this
is assuming equal temperament, with the octave being
a factor of 2, and each half-step in the chromatic
scale being the ratio 2*(1/12) (twelve root of 2)
there are many people investigating music temperaments
derived from phi-based octaves, but i was under the
impression that the standard diatonic scale had no
such recursion built into it. the circle of
5ths even leads to the "pythagorean comma" effect
that leaves the only nesting in the octave itself.
i'm really curious about the relationship between music
and light and everything else, so this kinda jumped out
at me. i've been studying beethoven and bartok and their
use of fractal circular melodies, but i've never heard of
there being phi relationships in standard diatonic scales.
thanks, brian
ps anyone interested in composing fractal and/or circular
music should check out "self-similar melodies" by tom
johnson, 1998. very interesting read, but you need
a decent music theory background to follow it probably.
alot of it is definitely over my head, but i've gotten
alot out of it anyway.
