This is perhaps a speculation of why A=440Hz ET and higher concert pitches can be perceived as a brighter, thinner, outward of the head, whereas concert pitch at A=432Hz 12T5 or C=256Hz can be perceived as an inward experience of feeling. Our heart has more morphogenetic fields than the brain and is one of the first things to form in the womb, beating out the soliton pulse of cosmic musical DNA. We feel our emotional bodies from the heart and our solar plexus is the nerve cluster that senses those feelings like a microphone or transducer. From my own observations, some of the harmonic overtone partials of A=432hz 12T5 appear to line up to natural patterns and also the resonance of solitons. Solitons need a specific range to form into the realm of density and span from the micro to the macro cosmos. Solitons are not only found in water mechanics, but also in the spiral ion-acoustic breath between quarks and protons. The universe depends on the existence of solitons and without them vortex motion would not form.

Some audiophiles have also reported that A=432Hz music seems to be non local and can appear to fill a room, whereas A=440Hz can perceived as directional or linear in sound propagation.

Whether you believe what it says or not, it's certainly an interesting idea. I'm going to tune my instruments down to A=432 and see if I notice anything different.
