Create symbols and assign a sound to each of them. For example, a star symbol can mean “clap,” a circle can mean to “stomp your foot,” a triangle can mean “hit the desk,” and a square can mean “snap your fingers.”

Put these instructions on a bulletin board or piece of paper and display it so the children can see. Then have the children compose their own music, using combinations/patterns of the symbols.

Then let the children each present their own music on the board and have the others perform their music following the combination/pattern of symbols.
