Stumbled upon these tonight. Thought they looked very neat. http://www.musictheory.net/index.html http://www.nyphilkids.org/main.phtml? http://www.dsokids.com/2001/rooms/DSO_Intro.html WOW! These sites are so cool! I'm so excited I found these. There is soooo much the kids can do with these. There are games, lessons, and so much more.
