It must be rough if your perfect pitch is set at A=440 and the band is tuning to something else.
I listened to those perfect pitch cds they always used to sell. The guy on there explains that it's not something that would drive you nuts. You know it's like "this is red, but it's not that red, but it still goes okay with this blue..."
I don't know why musicians make a big deal about this. I'm always having to listen to guys who really don't have it together telling me about how they're trying to work on their perfect pitch. Like if you could possibly have the discipline to nurture this ability as an adult, then learning all the musical stuff about music would be cake?? In the time it would take to create solid, practically useful absolute pitch, you could make a lot of jazz issues or whatever go away. You know, 15 minutes a day on a piano would be a lot more helpful than hanging out with some crayons and really concentrating on the wicked pissing contest you're going to have with some relative pitch loser.... okay, rant over, huh?
