This was very insightful. I myself am a music producer and a lot of the time I experiment with tuning my tracks to 432Hz. Its a warmer natural tone that differs from 440Hz. I find this tuning to be the very vibrations of natural and earth itself. This is maybe why we enjoy this tuning especially for acoustic and electric instrumentation.
Yep, but not all accoustic instruments have the right resonances at the right frequencies for A=432Hz. Thanks for your comment!
