Guitarfag here. Yes I too have heard of the 432/440 Hz conspiracy. Apparently the 440 is detrimental to our health whereas the 432 is harmonious. This can be evidenced by the water and salt sound experiments. There is plenty of videos about this on jewtube. Sorry to lazy to sauce.
There are also lots of videos about the 3,6,9. And the vortex effect.
Very comfy here, would rather Q didn't post here as i use qmap anyway. I popped into QR recently, it hurt my head. What a vicious place it's become.
I have up posting in QR, could never get through the captcha.
