If you have a touch screen just touch the screen to play. If not click the drums or cymbals to make your own music.
Play the Piano
To control the piano you click the piano keys to make music. The game is touch screen compatible, if you don't have a touch screen you can use a mouse. It is really cool in touch screen.
Just click, hold, and draw. Just like writing on a chalkboard.
I would love to see what games you are creating on Scratch!
