These groups lessons are FUN- nothing like what you expect piano lessons to be! Kids learn all types of music and how to read and compose too. A parent (or guardian) attends music class with the child- it's such a great bonding experience. The parent ends up learning a lot also! Just Google Children's Music Academy for (sorry-I can't seem to post a link for them).
Pros: Lots of class times & locations, best in town
