What is improv?
Improvisational theatre — "improv" — is theatre made up on the spot. No script, no rehearsal of the scene you're about to play. Just performers, an empty stage, and an audience.
Made up, but not random
Improv looks spontaneous because it is, but it isn't chaos. Players follow a small set of agreements — listen, accept what your partner offers, build on it, share focus — and from those agreements, scenes, characters and stories emerge in real time.
Two big families
Short-form is what most people meet first: snappy, game-based scenes (think Whose Line Is It Anyway?). Long-form is more ambitious — interconnected scenes that build into something bigger, like the Harold or a fully improvised play. Both are improv. Both are wonderful.
Where it comes from
Modern improv grew out of theatre games developed by Viola Spolin in Chicago in the mid-20th century, was shaped by Keith Johnstone in the UK with a focus on spontaneity and status, and was pushed into long-form by Del Close and the Chicago scene. Today it's a global art form practiced from São Paulo to Amsterdam to Tokyo.
Why people get hooked
Because it teaches you to listen for real. Because it rewards being yourself instead of being clever. Because failing on stage with someone who's got your back is, oddly, one of the safest places to fail. And because there's nothing like creating something that will only ever exist once.
How to start
Find a beginners' class near you, or a drop-in jam. You don't need to be funny. You don't need to be an actor. You just need to show up and say yes.
