Press various number keys to play various notes. Key below: 1: Middle C; 2: D; 3: E; 4: F; 5: G; 6: A; 7: B; 8: High C If you don't understand, play around a bit and you will soon. You only have an octave to work with. This is quite annoying, but you'll get the hang of it. I have. Don't press the same key too fast. It will sound EXTREMELY weird.
Another Scratch class project... But this time they're more unique :D
