Some years back our band became aware of this little (2 1/2 year old) boy (in diapers!) who was an exceptional being. He would spend the whole evening with us, hanging on every sound, leaving only to get an occasional saltine cracker from his mother. A member of the band lent him a piccolo banjo and his beat/rhythm was impeccable. I have always regretted that we didn't put it into an open tuning for him- I know that what discouraged him is that when he strummed it, it didn't sound the way he heard it in his mind. With open tuning the sound would have been pleasing to him.

He is now about 8 years old and taking violin lessons. We'll see.
