Celebrating the Vision of Merce Cunningham
For all his reputation as a master producer of impenetrably difficult modern dance, Mr. Cunningham's long voyage through the art of dance has been surprisingly simple. At heart, this journey of six decades has been a matter of "how adroitly you get one foot to the next," as he describes his notion of rhythm. "Something starts you thinking about other possibilities," Mr. Cunningham said in a recent interview at his West Village studio. "Because there always are. There always are."
That is what has kept him going. "I like dancing," he said softly. "It's very simple. Probably to most people it's absurd. But I really think dancing is wonderful. I can't do it. But I still enjoy the possibility of finding ways, finding out something else about it."
