I had never really thought about it, but there is a synesthesia thing going on here. It's just not mapped to one of the conventional senses. G# doesn't taste like anything, but it sure "feels" like...something. And not in the "external" touch way. And nowhere in my body but inside my head, as best as I can tell. I might even go so far as to say that this nebulous feeling is entirely the PP part of the sensation, totally separate from frequency. B-natural, for instance, has been ringing my head while writing this because I used it in some examples in the previous post. This B-natural, to me, has a certain "stuffy" feeling towards the front of my forehead
"Like those deep echoes that meet from afar
In a dark and profound harmony,
As vast as night and clarity,
So perfumes, colors, tones answer each other."
