Definitely some amazing outsider art, and an interesting read Humanity's been messing around with different tunings for hundreds of years (at least, in terms of western "art" music, which is my wheelhouse). We've gone all over the map, from A = 415 to A = 462, both of which are still in occasional use today for early music ensembles (415 being the most popular). I don't know about 432 specifically, but i'm sure it's been tried. I think any difference one might find will be from a lessening of tension on the sounding table of the instrument, and not any other cosmological phenomenon. Fun fact, there's an old law in NY still on the books that defines A as exactly 440 hertz. A bunch of opera singers, having difficulty with the raising of pitch (moving past 442 to even higher) to the point that they were losing roles because the high notes were moving out of reach, lobbied the government to put a law in place. Nevertheless, A still moves around today. Cleveland's at 440, NYPhil is 442, Boston is 441 I think, Toronto and Ottawa are 442. Vienna was 445 for a while, but is now 443-ish. That doesn't even get into the different systems of "well tempered" pitch (the ability to play all keys on one instrument, impossible with "Just" intonation), which are wide-ranging throughout history. Bach wrote "The Well-Tempered Clavier" to promote a well tempered tuning that no longer exists. edit: more cool info about this here:
