Repetition is good!
Granted, this quote comes from Missie's workshop on improvised poetry, but isn't repetition always good on the improv stage? Sondheim often said that on stage everything needs to be in service of clarity, without which everything else is meaningless. Repetition is a great way of increasing clarity in a scene.
Clarity is the absence of clutter. We avoid clutter by refraining from bringing too much stuff into the scene. Repetition therefore serves two purposes: it keeps us from bringing something new in, and it highlights something that was already there.
Yes. Repetition is good!
