It is too complicated.

It can be helpful for kids in their early developing ages. Because during the time of playing some a instrument, singing, or dancing; the eyes, ears, hands, mouth (singing), legs (dancing) must be very harmonized, and all these movements are coordinated by brain, the neural system. No machine or computer in the world (never will) can react so fast and accurate. This IS A AMAZING PROCESS which is following the music score! But most kids are too young to have mature thought. Some of them may be a good player or performer, but still limited in skills.
Music may be one of the training courses for child; for adults, it may function as entertainment or a way of relaxation, which also depends on personal experiences.
Actually I am a pure music blind, not qualify to discuss music. I hope to be a good listener KD. But sometimes, pour waters for fun.
Thank you very much for your article.
