My brother has perfect pitch, but on a level which is much more acute then most. For example, he can tell if an A is A440 or A439, and identify them correctly (we've tested it).
You should realize that there's a limit to how far that could go.
Would one go completely nuts if one had tinnitus that was out of tune?
What if when someone knew the pitch of their tinnitus they could develop perfect pitch
I think this perfect pitch thing is alot of hubub. Nothing's different and out of tune things don't send you up,the wall. What sends me up the wall are the friggin string players who claim that an 'A' tuned to 445 rather then 446 absolutely drives them mad. Ma vaffan.....
Reading about perfect pitch, they say that people who are exposed to tonal language (Chinese, Japanese) are born with perfect pitch. But I think any good musician can tell if 443 is higher in pitch than 440. What I want to know is, can you sing me a gb without any reference? And what if you can only do that if you really concentrate, and only 90 of the time? Once again, without ANY reference.
