This will be a bit shorter. Ever heard about the 432 Hz frequency? If not, research it right now.
My absolute "proof" why 432 is superior is this very simple maths:
Nobody about those, who talk about 432 vs 440, are getting this in mind:
Most of them should know what the natural harmonic series is.
So if we take a sine of 1 Hz (which equals exactly one second and equals the note C, which is why the german scale starts with C and not A.), double it we get 2. Add a half of it we get 3 Hz which equals a G. Multiply by 3 again we get 9 Hz, which equals a D. Times 3 equals A = 27 Hz. Go up 16 (2^4) octaves, we get to A = 432 Hz.
Those who know the harmonic circle also know that you are counting counter-clockwise and not clockwise. So you don't get from an E to an A but from D to A then to E. Just think halving the sine naturally.
