This year’s nominees for Tony choreography “represent three separate genres of show choreography. The first genre features dance and movement that are perfectly in keeping with the rest of the show without exhibiting any distracting distinction of their own. The second, a rarer type, is choreography that actually becomes part of the show’s inner motor. The third — and rarest — occurs when movement, dance and choreography are right at the center of the image that the work puts across.”
