The “432 Hz vs. 440 Hz” conspiracy theory
I have been following this for years, being both a sound engineer and a bit of a hippie who knows a lot of other hippies. The basic issue is that 432 is a numerologically interesting number compared to 440. So if it's more interesting it should be better for artistic purposes, goes the argument. However this falls flat as soon as you consider that the 432 is only interesting relative to the completely arbirtrary duration of a second. There is nothing special about the second from a human psychoacoustic point of view. We could have standardized on a longer or shorter time interval, but since we'd been using the Babylonian-originated divisions for centuries in the west the second is what we ended up with.But unless the music also contains some 1Hz modulation (or a power-of-two multiple thereof) then the 432 base frequency isn't related to anything fundamental in musical terms. Speaking as a DJ, if you take a track and play it a little bit faster or slower it still sounds great or awful as at the default speed in most cases. 432Hz vs 440Hz is a ~2% difference, while DJ equipment commonly allows for +/-10% pitch variation so you can match the pace of different tracks smoothly while people are dancing. Only the very tiny number of people with perfect pitch find this disorienting to listen to. If there were really something special about the duration of the second and the base pitch relative to that, you'd have expected it to emerge from dancefloors years ago. In reality 432Hz is basically cargo cult numerology, something fun to think about when you are not having any success coming up with a kickass tune. And kickass tunes derive their quality from the relative rations of the note pitches, not from some absolute Magic Frequency.Trust me on this. I really love numerology, sacred geometry and so on, and I try to integrate this into my artistic work regardless of medium. I would love for there to be some special key that would unlock the gate to cosmic/ biological/ quantum harmony and allow my artistic work to automatically echo the heartbeat of the universe. I'm a mystic by temperament and have been looking for such things my whole life. I would go so far as to say I have some religious faith in the significance of such things. But this ain't it.
