I just wanted to add something to what has already been said-
This is a great opportunity to teach the leadership and the other scouts about patience, encouragement, and understanding. My child takes approximately 5 hours to learn something that takes a typical child an hour. Once I was able to figure out the rough 5:1 ratio, it was easier to plan for it. My son can do everything his peers can do, he just needs the extra practice time.
If you throw a typcial child playing piano in a class where everyone else can learn by ear and doesn't need music, they will grow frusterated and think they are not good enough. In a different light, the child is perfectly "within normal parameters" and could be the best pianist of the bunch in the long run. It just depends on if you focus everyone's attention on how well they can play the piano or if you focus their attention on the fact that they can't play by ear.
It might be nice for each one of the scouts to be encouraged to "do a good turn daily" by giving the boy a call, an encouraging note, inviting him for a time to practice scout skills at their house, or a time when they buddy-up with him. It may also do well to have the troop earn their disability awareness badge.
Hope this helps.
