I was also bad at math as a youth, had a bit of undiagnosed dislexia and a bad attitude. Went back to school and placed into math 60. By the time I left colledge I had worked my way up to linear algebra and enjoyed most the journey I took to get there (not the hard work but the satisfaction of revealing the world with the tools I had earned). Music is an incredible thing to teach kids. They learn to make something greater than themselves. It teaches how to be a good follower and for many good leaders and team members. It helps to train kids to anticipate and prepare for the near future both the next class or performance and the next note it bar. It builds phisical and mental dexterity and it shows the elegance of a complex system and how it can be ordered to create usefulness and beauty.
