I have a similar "problem" with perfect pitch. If I tune an A to 440 and someone recognizes it as an A, fine. But as I start to loosen the tension slowly, when does it become NOT an A? When does it become officially an A flat? I say there are people who have pitch MEMORY. They recognize a pitch they have heard before and the name it was given, and anything close to that pitch qualifies as that note. I was unfortunate to start this argument about 14 years ago with a (now) friend who took the same tuning course I did. She claimed that her "perfect pitch" interfered with her ability to tune because of having to temper the intervals. However she also plays flute .. with other musicians. It is also my contention (and I am a violinist) that all instrumentalists who play together are constantly adjusting their pitch to accomodate the other players. I have no proof of this.
