Sixty-seven-year-old William Forsythe doesn’t look like a ballet superstar — he’s slightly built and he wears glasses. But the former dancer is completely at home in Boston Ballet’s rehearsal studio, wearing socks as he shows the dancers how to move.
He is known for deconstructing a dance tradition that goes back five centuries. There are times when he gets very theoretical about it. Describing ballet movements, he’ll say, “You have to vector it into space with very differentiated dynamics.” Other times he sounds very down to earth, saying, “It’s theater, we’re in show biz!”
