It has recently come back to my attention, that some folks consider our enjoyment of music to have been stolen from us.
This is the 432 vs 440 debate, in case you're not familiar. The understanding is, between the world wars, various europeans debated and finally agreed to define "A" as 440hz, and music being the highly mathematical thing that it is, all other notes are constructed from that first understanding.
Have you heard music tuned to 432hz yet? I've listened to a couple pieces, and find that the individual notes "agree" with each other better, where they are more raucous at the 440 standard.
This evening as you unwind with decaf, or tea, or whatever, consider the attached comparisons and make your own mind up about this debate.
