I have a new member in my choir who sings with great joy in the Lord, and more enthusiasm than most of the other members. One problem - she only sings one pitch. At least one choir member has complained that sitting next to her is difficult because of it. But we all love her dearly. Just yesterday she came to me and asked, "So how am I doing with singing?" It seems she knows she has a problem, and would like me to help her to work on it. I told her that I knew it could be worked on in some cases. I know some basic techniques, at least for teaching kids how to find their "singing voice," but I've never really done it before, one-on-one, and not with an adult. Any suggestions?
