Can't resist commenting on this.

NO. Everyone can't learn to sing. My older son is a monotone, which is a genetic trait he inherited from his father, my first husband. As much as he loves music, he is incapable of "carrying a tune." I don't know if monotones hear it wrong and reproduce what they hear or just can't reproduce the correct sounds.

But if you can carry a tune, you can sing already. Some of my favorite singers are the old-time mountain voices, the more primitive the better. I also like opera. Each has its appeal.

The first time I sang a lead in a jam session, I was mortified that I sounded awful. Afterwards, someone came up to me to say how much he enjoyed my song, and what a beautiful voice, etc. etc. It's all in your outlook. Sing out!
