Recently spiritimage sent me a link about changing the stadard pitch. I found it interesting because over the years many bands have re-tuned their instruments to different frequencies... especially lower ones. I have also used many different tunings to create unique sounds.
432 tuning mixes in here too
https://en.wikipedia.org/wiki/Pythagorean_tuningI don't think 440 should be the standard, International Standards Organization (ISO) endorsed it in 1953 , who I believe took this from German recommendations. So what, who gives them the right to say how we should tune?
I don't think Mozart and all these great composers of old used 440, I believe they all tuned lower.

I bet it causes some problems, and has been causing problems since the creation of radio and recorded media.
