This is the Rhythm Game! Play it and you'll accidentally learn how to read music! Real sheet music!
Each time you get 100% on a level, you'll unlock more levels! Click one of the blue skill boxes to get started. It's all about timing, so you can't play with wireless headphones—use your built-in speakers, or some good old-fashioned things with cords!
Your progress is automatically saved in your browser. Yay, automatic-ness! However, this does mean that if you switch browsers or devices, you need to get a special link from the button at the top-left.
Andy Van Ness made this. He's a band teacher at Linden Avenue Middle School in Red Hook, New York. Don't worry, he's not really as crazy as the narrator of this game is.
