Contemporary dance is a popular form of dance and has grown to become one of the dominating performance genres in New Zealand. It incorporates elements from many styles of dance, but it is often perceived as being closely related to Modern dance, Ballet and other classical dance styles. In terms of the focus of its technique, contemporary dance tends to utilize both the strong and controlled legwork of ballet and modern dance's stress on the torso, and also employs contact-release, floor work, fall and recovery, and improvisation characteristic of modern dance. Unpredictable changes in rhythm, speed, and direction are often used, as well. Contemporary is a non syllabus class but the pupils work on similar repertoire each week to build up their strength and technique. Pupils are encouraged to incorporate their own rhythms and ideas into the class.
