I actually prefer it if I don't know what I'm supposed to do. If you've got an equal temperament piano keyboard, then you know what you're going to get if you play certain chords. But I actually like it if you don't know where the notes are, because then you do it intuitively. You're working out a new language, basically. New rules.
There's something wrong with my brain, it doesn't work properly! I can hear the same pitch in both ears, whereas for most people, if you listen to one pitch in one ear, it's slightly different in the other. That's how your brain works out direction.
