Man.
I had to read some absolute junk in researching this topic, which has been requested quite frequently. Basically, I tried to create the definitive video on all of the reasons tuning to A=432 really isn't a thing. I mean, you could if you wanted to, but literally none of the reasons have anything to do with 1) math, or 2) sacred geometry.
I admit, I was a bit hesitant to do a deep dive into this topic, because so much has been said before about it. It also feels like almost too easy of a target, but I thought it would be a good jumping-off point for a discussion of how concert pitch has evolved and other issues regarding temperament.
Hope you enjoy this one!
Peace,
Adam
