I have been reading about tuning musical instruments to A=432 frequency instead of recently (meaning in the last century) arbitrarily defined standard of tuning to A=440Hz.
Supposedly the 432Hz frequency and its derivative tones have been "naturally" developed standard of tones through past. These tones are supposed to be common in some dislocated primitive tribes or communities like shaman's chanting, native indian flutes, tibetan "chakra bowls", etc.
Some claim that instruments tuned to A=432Hz "just sound better".
It is claimed that old classical music was originally composed and played in these frequencies.
Also when the 440Hz standard was set in previous century, many musicians protested against it.
The temperament that is suggested to be most "natural" is Pythagorean.
What do you think of it?
PS: in my opinion there is a lot of disinformation, false claims, sellers of "healing divine sounds" which makes investigation into subject somewhat difficult for me. At first glance I would easily dismiss any such debate as a new age hoax, on the other hand one may quickly fall into spiritual faith thing.
