Teach: Don't go too fast. Encourage exaggerated diction and over-emphatic performance, injecting as much melodramatic interest into each word as possible while preserving rhythm. Emphasise importance of eye contact, nodding and so on. (By contrast, ask for completely deadpan performance.)

Add some simple notes (e.g. a simple scale, change note each bar) and try to preserve extreme diction and performance.
