Applying Stanislavsky's techniques to playback

For the this term, I have been doing playback theater as an extracurricular activity. Playback is about interpreting the audience emotions, is about celebrating the audience's stories. The actors are responsible of representing this stories and emotions into different forms.

The actors need to make this representations of emotions and stories very quickly, right after the person tells the story or the emotion. It is useful to think about different ways of representing emotions before, but at the moment of the performance it is completely improvised as it depends on what the person shares.

I have tried to use repetition and I think it works to represent the emotion as clearly as possible. Emotional memory is not very effective in this case because there is a very short period of time for the improvisation. However, repeating the emotion that is about to be represented or a phrase that relates to that emotion can let the actor feel more identified with it and come up with more creative representations of what this person has just said.
