What is the KEY?

What happens if we think of theatre in terms of natural physical phenomenon? What is the landscape of theatre? What is inherently in existence before we create something? What are the elements of theatre that transcend creating and originating? What is it about theatre that we must observe and participate in? What is the inherent natural landscape of theatre? What force is at play that we are compelled to participate in and observe as artists? What summons our creative force and gives us the inspiration to act on that force? Is it as simple as SPACE, SHAPE, TIME, EMOTION, MOVEMENT, STORY?
