The most important thing I think I’ve learnt at improv recently is the importance of change on a scene.
You can take a really strong character with a really strong emotion and you’re off to a great start. Once you’re in there, with the other player, you can start having fun, but once the relationship and location and all that jazz is established, it’s easy to get stuck in a rut.
Personally, I know I’m in a rut when my stress levels peak out – the panic sets in that I’m at a dead end.
Luckily, change will get you out of there.
Your strong character can have a change of heart – in any direction – and it really breaths new life in the scene and gives it a direction.
It also seems to point it to a resolution, which is nice.
