Passage Two
Martha Graham’s territory of innumerable dances and a self-sufficient dance technique is a vast but closed territory, since to create an art out of one’s experience alone is ultimately a self-limiting act. If there had been other choreographers with Graham’s gifts and her stature, her word might have seemed a more balanced part of the story of American dance. But as she built her repertory, her own language seemed to shut out all other kinds. Even when an audience thinks it discerns traces of influence from other dance styles, the totality of Graham’s theatrical idiom, its control of costumes, lights, and every impulse of the dance makes the reference seen a mirage.
