Using Yat Malmgren's Character Analysis, I am able to identify the 'type' of the character you are auditioning for, as well as you're own energetic type, and how these two may merge to either fulfil the brief, or challenge it with a fresh perspective.
As an actor, coach, performance dramaturge, playwright and screenwriter, I can safely say that the actors who understand type are the ones who thrive in their careers.
