1) What is the numerical value of this "twelfth root of two?" I don't
think I have either a sufficiently advanced calculator (or program),
or sufficient calculation skills, to figure that out...

2) Just a thought...if, as you say, "It doesn't give the exact ratios
for any chord"...is it not, then, a practical approximation...or, as
we used to say back in my USAF days, "Close enough for government

3) Does "from note to note" allow for the fact that some notes in
the major scale differ by full tones, while others differ by
half-tones (i.e. there is no C-flat!)...or were you speaking of
the series in a twelve-tone "scale?"

I'm not challenging you...I'm just trying to get as full an
understanding as possible of how...and why...western-world
music "works!"
