As a child, I endured 18 months of DelCatto therapy. Delcatto therapy forbids music. I don't know why, but it does. The therapy is born of (seriously flawed) science. It purports to fix damaged brains. It didn't fix mine. I also had to crawl in the approved DelCatto style for 45 minutes a day. I was supposed to walk like a chorus girl pretending to be a robot. (That did not happen.) and sleep in a special position. (You're kidding, right?) Science has caused it's share of unhappiness too.
