Oh, it very well could be, I don't know much about those instruments. I meant that's how most instruments were tuned, before the 40s when several countries agreed on the 440 Hz standard, which isn't divisible by 3, in other words, 432 Hz allows for more harmonies.

440 Hz is more dissonant, and causes us to be more warlike, hence the 20th century.

You can modulate music tuned to 440 Hz to 432 Hz, and it sounds nicer. I know of several musicians who write 432 Hz music, Brian T. Collins being one of them. Also the songs "Three Little Birds" and "One Love" by Bob Marley, and "Imagine" by John Lennon, used the 432 Hz tuning as well.
