Bob K. allows me to brag:
>Anyone else experiment with learing perfect pitch?
Never had to. I don't have perfect pitch, but I have something just as
good. Blood rushes through my right ear at Eb and through my left at Bb.
With those two tones as anchor points, I can find any other pitch.
When I was singing a lot, I could "feel" the location of the D above middle
C, probably because that was about where my "break" was.
