What are Circles of attention?

Stanislavski used circles of attention as an acting technique to aid characterisation. all three are achieved through FOCUS and CONCENTRATION The first circle involves concentrating on the self, it provides the actor with a sense of isolation and avoids unnecessary tension.The second circle widens awareness to the other actors character that you are addressing in the scene The third circle extends to the rest of the production but NOT the audience. Making the character aware of ones surroundings and then drawing back in is important for characterisation.
