Follow the Leader

Jambo and Jasmine play a song, but Jasmine is bored: she always has to play the same four notes and she can't sing. Because they don't agree, Jambo goes off angrily. Jasmine follows him, imitating all his gestures. And after her, their other friends join in. This gives Jambo an idea: if they sing the song as if they were imitating the person in front of them, they can do a canon in which they can all sing.
