It's an interactive teaching program for learning how to read and play classical musical notation. You can use your choice of instruments, though it has a lot of focus on guitars, or just sing and try to match the notes. Nootka will listen via your microphone and judge how you are doing, but without any snide Simon Cowell comments.
