On a more serious note, I've had perfect pitch since I could ever remember, both in the absolute sense and the relative sense. So I have very little trouble transposing at sight, as well as playing at sight, or keeping in tune when singing a song in different keys. I've never known how I do it - I also have a pretty fast learning memory for music too. But, oddly enough, I'm lousy at matching names to faces.
I don't have [or have never tested the possibility of having] perfect pitch. I do, however, have an unerring sense of direction, and can point to North however many times I've been spun round. Is this normal?
