Re: How many of you have perfect pitch?
Which is how Steve Vai developed his perfect pitch, by taping A440 and playing it back on a tape loop overnight. Everynight.
I used to know a guy with perfect pitch, not relative pitch, pitch memory or "off by a few cents, nearly perfect pitch" but perfect pitch. Back in school I played in the classical orchestra (percussionist - because drummers need extra curricular credit too) and this guy could pick out one of the violinists from in the orchestra to say they needed to tune up. He could also sight read anything on piano. He ended up running the school orchestra taking over from the teachers because he was so musical.
Remember the line in "Ghostbusters" - "You're good, most people can't hear me with the whole orchestra playing" it didn't apply to that guy...
I think he ended up as an architect!
