Technique, as any good teacher will tell you, is a means to an end, not an end in itself. In the 20th century, when modern dance was born, it seemed nearly every choreographer wanted to distinguish herself with a specific style and technique. Numerous camps developed as dancers, students and professionals, aligned themselves in balkanized fashion with a specific choreographer or technique. You could tell a Graham dancer by the way she held her chin and wound her hair in a high, full bun. A Dunham dancer? The walk, like coursing through a sandy beach, gave it away. But today, choreographers and artistic directors demand versatility, not allegiance. The ability to remain flexible enough to tackle any number of stylistic or technical demands is what divides good dancers from great ones. The techniques below may be built on differing foundations but the end result remains constant: well-trained and adaptable dancers.
