Revised "very final" version of Tuvans

For Paul Erlich (and anyone else interested):

Hopefully this is the "very final" version of my Tuvan paragraphs, which I
can, possibly, turn into the "final final."

If this is OK, I'll run with it...

Thanks!, Joe

It so happens that sounds made from the vocal cords produce a whole
spectrum of "little sounds," overtone frequencies that are heard at the
same time, and which produce the "character" of the basic tone. These
overtones are in simple harmonic ratios to the fundamental pitch, 2/1, 3/1,
4/1, 5/1, etc. In addition to these vocal cord harmonics, the vocal cavity
has its own acoustical properties. There are certain "resonance
frequencies" that are present in this closed space. There are several of
them, coming from different parts of the enclosed vocal tract.

To produce their throat singing, the Tuvans work to align the
naturally-occurring resonances of the vocal cavity with one overtone at a
time from the vocal cord harmonic series. They do this mostly by changing
the shape of the vocal cavity with their tongues. When this happens there
is magic -- the harmonic of the voice tone is strongly enforced, resulting
in a disembodied "whistling" effect that sounds quite a bit different from
anything we would expect to hear coming from a human mouth.

Beautiful!
