Several years ago, an orchestra teacher at the school my husband also taught at, mentioned a computer program that you could play an instrument to and it would grade you. I can't remember the name of the program, but thinking about it just made me wonder about the possibilities of learning with today's technology. If you consider the XBox Kinect and its ability to recognize a player's movements to interact with a game... what if a program was developed for teaching violin? Something that could recognize your posture, the position of the bow, and listening to your intonation and give you feedback based on all of those things... wouldn't that be amazing?
