Hi B.,
There is a great place called the Suzuki Institute that specializes in a method for teaching young ones (3 yrs +) violin, cello, piano, etc.
We have started taking my 3 1/2 yr old there and it is amazing what these kids can accomplish when started so early with something they have an interest for.
Check out www.suzukidallas.com for info on their teaching method, classes, etc.
There are many instructors under one roof that offer private lessons as well as group lessons.
Good Luck!
S.
