I hesitate to mention the following because I cannot remember where I saw or heard of it. It might have been in a medical magazine, possibly the newspaper, but I cannot find the reference. The article said that people who have perfect pitch process sounds in a different part of their brains than normal people. The study was done with a nuclear magnetic resonance scanner, scanning the brains for chemical activity changes while tones were played to the patients. That is all I heard, I have nothing to add, no references to the study. I thought I would relay the information in case someone else can actually put their hands on the article, or scan search the Internet for such things. Bill Simon Phoenix
