Planck's Glissando

Hi Kraig,

What an interesting question. If we figure this out, do we have
quantum music? Would that be JI or ET or ?? :)

I don't think quantum mechanics is normally applied to sound, but
I suppose it could be. It seems the practical answer to this
question is that Planck's constant is so small (6.626 x 10 to the
minus 34) that it's effect on a glissando wouldn't be discernable
to the average listener.

>If so, what is the octive equivalent of this fundamental?!

The Handbook of Chemistry and Physics give the units of Planck's
constant as J Hz -1. I suppose this might translate to a
wavelength in some physics phantasy. The reciprocal of Planck's
constant gives a frequency of 1.51 times 10 to the 33--a little
higher than most people can hear.

Are the listers aware that Max Planck wrote a lengthy monograph on just
intonation and singing? A friend of mine made an English translation.

Significant differences are heard in the glissandi in my bassoon solo Dune
between digital and analog recording. On the new CD (any month now -
called _Raven_) the glissandi take on an "other"-instrumental quality to
my ears.
