Well, as long as you are going to be okay with endlessly editing every sequence you use, every audio track you ever play with, make sure that every musician you play with feels the same way you do about 432hz and is willing or able to retune, and every piano you play comes with an on-call tuner to detune it and then tune it back up again after you leave for everybody else who doesn’t feel the way you do, you are good to go! 🙄😂

Best of luck finding loop libraries recorded at 432hz! And don’t try to kid yourself that merely pitch transposing them down to 432hz from 440 will give you the same moiré pattern in sand as one recorded at that pitch. Remember, the pitch may have moved, but the formants will still be inextricably tied to the original pitch.

Bottom line… you have chosen a path that few other people care enough about or can even recognize to be worth the bother and inconvenience you are going to inflict on yourself and everybody you play with. If you have no intention to ever play with somebody else, sure, you want to create a mountain of work for yourself, have at it!

But now might be a good time to think about whether you wish to inconvenience everyone else for something next to nobody gives a rats about..? 🎹🤔
