Aaaaargh

So, the hymn of St John the Baptist... Ut Re Mi Fa So La, yeah, that one. The sheet music is on wikipedia, and it clearly shows ut as c, re as d, mi as e, etc. Makes perfect sense. Until I came across the Solfeggio frequencies, which are based on the hymn. 396 hz? That's not ut, that's close to today's g (392hz). And lo and behold, Horowitz in his Healing Codes for the Biological Apocalypse lists them as 396 = g. It kind of makes sense, but boy, did it take me some thinking. He mentioned on one occasion that the combination of mi and sol is destructive, and my first thought was, what a fuckwit. I mean, seriously, e and g as destructive??? Get rid of all the classical compositions then. *snrk* But nooooooo, that's not at all what he meant. C followed by the next higher f-sharp. Yeah, definitely destructive. But hell, how am I gonna figure out how C moved to G??? *iz lost* Cuz I'm sure I'm missing something. C4 is pretty close to Mozarts idea of 256 (258), A440 is of course utterly out of place, but then, yeah, no surprise there. Anyone can shed any light on this transformation from ut=c to ut=g? Cuz, really, I'm utterly lost.
