In today’s episode of random unexpected facts it turns out that A at 440Hz is an ISO standard, and previously an international agreement on setting a standard pitch was part of the treaty of Versailles which ended WW1.

@J12t Without that standard, Randy Jackson wouldn't have been able to say, "Yo, dawg, that was pitchy." The singer could simply reply, "Sez you. I _like_ my A at 444."

@J12t Wow, synchonicity. Just yesterday, I was reading /The Commodore/¹ to Dawn and came across:

“Jack tuned his restrung fiddle: they talked for a while about pitch and how some people maintained that A should sound *thus* – Jack played the note and said, ‘I cannot bear it. I hate to think that our grandfathers should be such flats.’ …

@J12t The 1885 Vienna conference agreed on A = 435 Hz.
