INTERESTING! I grew up with a musician who was cursed with "perfect pitch." I well remember when he walked into my parent's home as I was vacuming the floor. He unplugged the machine, and said: "C SHARP!". He went to piano, played a key, and sure enough, the noise of the machine was C SHARP.
He had an astounding musical career: concert violinist, orchestra conductor, teacher, on and on. But he was constantly cursed by his "perfect pitch." Elevator music, folksingers, the poorly tuned guitars drove him nuts! bob(deckman)nelson
