Perfect Pitch

[Raymondbl]

I seem to have perfect pitch subconciously but when I'm actually trying to find the right notes it doesn't come.  Once I was having a haircut and was having fun humming chords, and somehow my fingers were playing a B-flat major scale.  Immediately after I found out at the piano the shaver was running at B-flat. 

The only pitch I can conciously find is A.

I think I have perfect pitch, as long as I hum the note in question. I've gotten so used to tuning the timpani (even though I'm not a percussionist) that I can tell the note.
