Scrump: I've sung with wonderful singers who can't hear that they are singing in the wrong key. Even when I play the whole song through as an introduction, they came in on a different key. When I tried to get them to sing harmony, they usually slide back into singing the melody. When I try to teach them the harmony and sing it for them, they sing along with me, with me singing the harmony and them singing the melody, and when they finish they say very comfortably, "o.k., I got it now." That can't even hear that they are singing different notes than I am. And yet as a lead singer, they have fine tone.

In this case, it's usually because the person has always sung lead, and expected the accompaniment to follow them. I've heard these singers go through a whole song, singing in a different key than the instruments and back-up singers and think everything was fine.

I have no idea why they can't tell the difference. Some of them are really wonderful singers..
