The narrative goes something like this: "I can sing. Why should I bother with voice lessons." It's true that some people are born with better singing voices, just like other people are born able to run faster. And just like practice running under the regimen of an experienced coach or trainer helps a runner run faster and longer while avoiding injury, training your voice under the guidance of an experienced teacher helps you sing stronger with a better range, more control, and less risk of straining your vocal cords.
The class is 30 minutes length per week, see website for more info and to register.
