[Harp-L] RE: 432Hz and the "scientific" reference pitch... Wierd

[Dan Hazen <bluesmandan76@xxxxxxxxx>]

Found a couple interesting reads on A=432Hz... apparently it's an variation
of the "scientific" or "philosophical" reference pitch proposed by a
physicist named Saveur. Something about all the octaves of C being
represented by round binary numbers. It's actually originally more about
middle C being 256Hz than A being 432Hz... (apparently it's supposed to be
430.54 Hz, but people adjust the temperament with the "pythagorean
temperament" to stretch it up to 432.) Kinda neat, but also kinda weird.
There is a lot of weird new agey stuff out there about A=432. Until someone
can prove that birds all sing with a particular reference pitch or
something, I just don't really care about reference pitch.
