My wife Christina never could sing, but she joined the church choir because I was in it (somewhat to my chagrin). We have a terrific choir director, and she realized right away that Christina was trying to sing in the wrong range. Now Christina is singing alto, and feeling really good about it.
For once in her life, she really feels like she can sing. And the altos have taken her under their wings - and they especially like it because Christina is a chiropractor and gives massages to the whole choir...
