Nazis were also the ones that started to use fluoride in the water, because they knew it would make people apathic. A small coincidence?? Maybe.

My experience with playing 432hz tunned guitar was that I seemed to be alot more creative when improvising. Coincidence also, maybe I was just having an inspiration moment. But you can't escape the 440hz if you want to learn an instrument. And it is boring to change tunning all the time.
