having attended an institution that offered degrees in music therapy, I don't put a whole lot of stock in it. I mean it's a nice idea and a good concept, I'm just not sure of the quality of the people practicing it. The addage in school was, "Those who can, do, those who can't teach, and those who can't teach go into music therapy."
So, I guess I'm just warning that if you find one, do your homework and find a good one, otherwise you're going to end up with some fool baning rhythm sticks for 30 minutes or whatever else the book told them to do.
