I believe that there is a wide variation in the precision of "perfect pitch", and it varies from individual to individual. A local tuner did a survey of his customers with this affliction, and found that it varied in accuracy and also was dependent on instrument producing the note in some cases. I have a customer with perfect pitch who wants half the top octave tuned 8 cents sharp, but only those notes. Hey, its not my piano! Patrick C.
