Choreography cannot exist without movement - movement not in the sense of dancers moving, but in the sense of a kinetic substance which is in constant movement. The fact it happens while time is moving forward, is not enough. The duration of a choreography is completely separate from its own movement through the 'theatrical time'. A constant sense of movement through that particular performative time, must be present. By the time it ends, a choreography should be at a completely different "place" than the one it started at. It has moved, on a totally different time plane than the passing of time.
