I am very interested in this subject, as I have absolute pitch. At university, a sizeable minority of students in my year had it too.
Do you have it? Is it a help or does it cause problems? Do any of your students have it? (I have been surprised that only three over a twenty year period of teaching have had reliable absolute pitch - many more "nearly" people). I am surprised it is less common in the general "musical population".
If you have absolute pitch, do you also have synesthesia too? I hear in colour and associate many pitches with specific colours (e.g. and A is red, F sharp is dark purple). I know that much has been written on this subject, and my apologies if I am duplicating a prior discussion, but I would be fascinated to hear other personal experiences.
