Sorry, but I could not resist jumping in here. Firstly, there is no such thing as perfect pitch. Honest. It is sort of the aural equivalent of idetic imagry, or "photographic memory". To regard 'perfect pitch' as such implies that there is some cosmic standard out there, perhaps the music of the spheres of lore. What you suffer from is pitch memory, and it is a learned skill/curse. I knew a guy in high school who had "perfect pitch" at roughly A=415. Owen Jorgensen once did an experiment in a class of doctoral music students, and set a temperament chromatically without referencing to previously tuned notes. Each was settled upon by all of the students who had perfect pitch. The result was, well, I believe the word he used was "horrendous". Apparently triads worked in only a couple of keys, and the octave would make Pythagoras' teeth ache. As for the curious customer, I always try to demonstrate a bit of elementary "beat theory" for them. A little interest seldom translates into a real running dialog unless you allow it. I didn't stay 22 years in this peculiar business so much for the pianos as for the customers. In the words of fellow tech Phil Bashaw, "I only tune for my friends". Unless you encounter a real neurotic, you may want to just gently explain that your brain is incapable of two things at a time, and while you would love to spend more time with 'em, you make a lousy conversationalist while tuning. They get the picture. You get a customer and a reputation as a great tech. Steve
