Pythagoras was pretty dope, from geometry to harmony. I'm all about A=432hz, but need to actually start using it. Thanks for sharing, cheers!

Interview with Aphex Twin and his tuning preference: "I’ve since gone on to learn more about this damn 440 Hz. It was a standard introduced in 1939 by western governments, so I’m very glad I trusted my instincts. Listening to that other voice is THE most important thing in creativity, whether you’re an engineer or a musician. Tesla had some important advice on listening to the thoughts from the other. One of the most important inventors ever, but we’re not taught about him in British schools. Funny that."

I totally agree that just because you can't feel the sound with your ear drum and hairs doesn't mean that you don't feel it in your bones ect. Hearing is really just feeling the air. Inaudible sounds also effect sounds we do hear. And then you get into chakra vibrations and it starts getting crazy. This is kind of interesting:

This is actually what I meant to post. But it all comes back to Pythagoras and his discoveries in harmonics. Whatever length you start with, nature has it's way of portioning things out.
