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.

Tuning and temperament are not related. Temperament is the spacing of notes relative to each other, while the tuning you are asking about would move all notes by the same amount. –  endolith May 11 '12 at 19:38

The title is intriguing, but I don't see that claim that 432Hz is "beneficial to the body" cited anywhere. Without that, or some other concrete claim, this is just asking for opinions. –  Flimzy May 11 '12 at 20:37

OP is correct that this claim is in the air in various paranormal / woo communities: cf attunedvibrations.com/432hz , omega432.com/music.html , ashtarcommandcrew.net/profiles/blogs/… . –  Evan Harper Aug 26 '12 at 22:50
    
We don't have the scientific capacity to really test this except for significant, short term, effects that fall within a certain domain. All that we do know is that small differences in frequencies can elicit observable different responses in matter within the right scenarios (Cymatics). So talking about the benefits of different frequencies isn't conjecture, but it is still just speculation at this point. –  James Christopher Oct 20 '13 at 10:35
    
The second link is broken/dead. First link makes no claim about whether A=432 standard sounds better or has any other benefits, and only mentions it along with other proposed or sometimes-used standards. –  iamnotmaynard Jul 17 at 19:19
