I think there may be at least two parts to this. Sound itself definitely can have an effect on the chemical basis of mood. I've read for years about
endorphin release and soothing music (although a quick search to source that claim failed to turn up a plethora of double-blind experiments on the
subject) and Muzak's effect on people, positive or negative, is well known.
Some kinds of music will soothe me, I will physically relax, my capillaries will contract less in parasympathetic response, blood flow to my
extremities and viscera will increase, and I am physically healthier. Other kinds of music have other effects.
Frequency itself (A=440?) can produce these effects but only very briefly. It's the perceived interplay between the frequencies that sufficiently
engage my mind for these prolonged physical effects to be produced. Different scales based on different frequency patterns will have the same effect
on the listener if the perceived interplay between the frequencies is the same.
The other part seems to be imperceptible to us but the effects are no less real. The interplay between frequencies, if timed correctly, creates a
"pulse". Like two waves merging and creating a third wave motion. Our brains work at very low frequencies, roughly 3 to 40 Hz. Everything in the
Universes is, by entropy, convection, conduction, diffusion, et al, endlessly approaching resonance. Our brains "attempt" to match these local
"pulses" just as air tries to "match" the frequency of a falling tree.
Whether A=440 or something else, I think what counts is giving the mind a toy to engage it while the body responds to its natural inclination to heal
and then creating "pulses" that affect the mind.
Reading over this, I worry that I sound as if I think I'm an authority and I think the opposite. This is an intriguing question for me that I've
been looking into a while and have more questions now than before. I'm not dissing the idea that A might better be another frequency but I do think
I've noticed it's the interplay between frequencies that have, at least, physical effects.
