As a musicians, my ears are really important to me (wish I'd thought of that when I was young) and I try to take care of them so as not to lose any more pitches than are already gone.
A musicians forum I frequent has a thread about a pitch/musical phrase hearing "test" that took me there to take the test. I scored 86.1. I'm not sure how that really effects one's music but it is interesting to do.
Find the test here.
How'd you do?
