I love this paragraph from the article:
The music belongs to children just as much it belongs to "us" — the ones with the years of listening experience, who have already absorbed current conventions of concert-going practice (don't applaud between movements, obey the dress code, etc.), and who might well have had years of formal training. Classical music isn't a museum piece to be looked at and not touched, as it were.
From the video included at the end of the article, I also discovered some fun videos for youngsters about classical music. Take a look!
