i always thought it was the person who was tone deaf or fell asleep at concerts that was the opposite of musical (piano oriented). or, could it be saxaphone players? trombonists? have you ever met one, and they think they're better than you because they can jam. my bro, for instance, when he dutifully took his piano lessons (around the same time as i did) would make stuff up whereas i followed the notes. then, he decided piano was too predictable for him, and he took up sax.
