I'm a big fan of music education. There are numerous studies that demonstrate how good music is for the brain. Music can foster responsibility, cooperation, coordination, socialization, organization...the list goes on. There is no doubt that music is good for people in ways you could hardly imagine. And yes, as an additional form of expression, it can be a tremendous outlet for young people learning to process and express their emotions in healthy ways. I strongly suggest that you invest in a good, student-level instrument for your child, and find a good teacher. Good instruments are easy to come by. Good teachers, not so easy to come by. Suggest you interview several teachers, and then pick the best one. A good teacher should be able to adapt their teaching methods to the student's particular learning style. I have been fortunate to have found good music teachers for my son, who plays clarinet, piano, guitar, and is now learning saxophone. Good luck!
