I think the definition of musical skill has been covered pretty well..and far more eloquently than I could muster!
However on the subject of music having value - it's my experience that children who play musical instruments tend to display far greater social skills and far less anti-social behaviour than those that do not.
With todays very prevalent anti-social, 'me me me' attitudes - we would benefit from having as many musical children as possible!
There have been numerous studies in the US that children that play musical instruments also do better at school, suffer less alcohol and drug related issues and tend to go on to have top level jobs. My memory on this is very fuzzy but something to do with 75% of the workers in Silicon Valley play musical instruments of some sort.
In short...yes, musical absolutely has value to children and society.
