I have met some very competent musicians who have found 432 tuning to be powerfully effective. When I dug into this, I discovered they were tuning the other notes in the scal to frequencies in whole numbered cycles per second, using tables being passed around. So the real change was in the qualities of intervals; many of these became far more resonant than the compromised resonant qualities we get with equal tempered tuning. This trade-off was once well known in the musical world, but it is now long forgotten. I consider "432" to be a symbol that suggests the restoration of forgotten methods for tuning scales, rather than a literal value to be used to proportionally change the frequency of every note.
