 Listen to the rhythm played, and follow along with the music. If you would like to hear it again, click the play button. When you're ready to perform the identical rhythm, click the drum to the rhythm, then click the ok button. If you clicked correctly and in the right tempo, another rhythm is displayed. If not, you must try again.
