For 2 years now(not counting the first two years he had been playing because we focused on his notes first and foremost) we have been working on his stage presence, how to animate yourself while playing and being more expressive while playing. I call it "showing off". It is easier for him to understand what showing off means and what child doesn't like to show off. But I gotta tell ya, and I am not being the least bit sexist by saying this, it is super hard for a boy who just turned 13 to be expressive. He feels embarrassed and doesn't want anyone to poke fun of him because he "moves" while playing. It is akin to a boy dancing. He hates to dance for whatever reason. As adults, it is hard for us to understand how a child feels when they are asked to "dance" in front of people but I totally get it. His teacher also wants him to sing certain parts and like dancing, not only does he hate to sing in front of people, but that embarrasses him as well. And again, I totally get it. So it is a struggle to get him, as well as other kids(especially boys)to open up more and not be embarrassed. Ultimately, all we can do is be their cheerleader. It is up to them, of course with enticement from us adults and parents, to overcome how they feel. So having said that, he is taking baby steps and in this video, I think he is looking so much better being expressive....or showing off. Hey, whatever works, I will call it whatever it takes to help him.
