<p>Not sure about the age requirement, but University of the Arts in Philadelphia runs a wonderful summer MT program that is nonaudition and quite reasonable financially compared to many others. My rising junior daughter went there last year and had a terrific time, and learned and grew so much! I was very impressed with the organization of the program, the instruction, the care given the kids and the individual evaluations they wrote on each student. It opens up for registration in early January, I believe, and is on a first come, fist served, basis. I believe you can find it under the Continuing Education part of the UArts website. I highly recommend it!</p>
