Press the flag to start. Then press any of the number keys (0-9) to play saxaphone notes and make your own song. You can play multiple notes at one time. 4-1,4-2, and 4-3 sound really good together. If you want to play Carol of the Bells you can either do 7-6-7-5 or 3-2-3-1. On the piano, you use the other hand and play A,G,F, and then E so you could try doing that (5-4-3-2).
