When I was a little kid, (around 3 years old) my parents discovered that when I sang tunes from cartoon shows on tv, I would always be singing them in the original keys that they were recorded in.

To this day, I hear all (commercial) music in my head, in the exact keys they were recorded in.

I can tune a guitar precisely to A440 as the relative reference point, without the need of any external tuners.

You can blindfold me, and have me stand half way across a room, and hit any note on a piano, and I'll tell you which one it was in a second. Same applies to any chords. (Came in very handy in doing spot-on lifts of popular tunes when I had my band.)

Yet, I cannot sing or carry a tune if it had handles on it.....but I can detect the slightest inaccuracies in pitch of any music or vocalist I listen to. It used to drive me insane. These days I just ignore it or laugh and think ''amateurs'' to myself.

But my vocal chords just don't want to cooperate. It's a piss off....but is probably why I tend to focus on creating instrumental music most of the time.

Go figure.
