This has just given me an idea for a whole new form of musical entertainment in which the members of the orchestra have to act out a story as well as (or in-between) making music - a sort of instrumental opera. They could do things like falling asleep, falling in love, having fights, passing notes to each other, making fun of the conductor when his back is turned, stealing someone else's instrument, etc. It would be quite hilarious if the audience weren't expecting it. ( But no doubt someone is going to tell me it's already been done!)
