I think it is totally irrelevant what the exact pitch is. I play guitar for over 40 years and I rarely tune my guitar exactly to 432 or 440, instead, I often tune my guitar about a whole note lower because I like the sound of the strings with less tension. Whatever the pitch is, I have my moments playing great and playing terrible. If there is one special quality that might be heavenly then it is the artist composing or performing that beautiful piece of music in the moment, and I never experienced that moment being connected with 432hz in any way.
