We had a guy in our college band with perfect relative and absolute pitch. One time we walked out of the dorms and the AC was squealing on top the building across the street.
"Hey Dave, what note is that?"
"Do you really want to know?"
heads nod
"It's a G"
One of the other tales was someone with true perfect pitch could tell the difference between A at 440 vs 441 hz.
- dekhn 6y agoI've seen this. When I was in grad school I was playing with assembly language to click a speaker in a timed loop, such that it would generate A440. I played it to my coworker who was working in my lab, and he said: "I'm a singer and I have perfect pitch. THat isn't A440, it's slightly low. Probably one hertz." I checked my code and indeed, I had miscomputed the timer, it was slightly longer than it should have been. Fixed the code and he confirmed it sounded better, but not absolutely perfect.
- filmor 6y agoAC squealing (and a lot of other noises that are somehow synchronous to the grid frequency) would be a slightly off G outside of North America (slightly to high, G is ~49 Hz and the grid frequency almost everywhere is 50 Hz), no need for perfect pitch to guess that. In North America (60 Hz grid frequency), I'm not quite sure whether one would recognise it as a A# (58.3 Hz) or a B (61.8 Hz).
