Contra body movement
Contra body movement (CBM) is a term used in ballroom dances, such as Waltz, Foxtrot, Tango, Quickstep. It describes a specific coordination of the movement of dancer's body when doing or preparing to do a step with turn. CBM is turning the body during the step towards the moving foot. It means that, e.g., if the left foot moves forward, then the torso rotates to the left, and when the left foot moves backwards, the torso rotates to the right.The overall effect and intention of CBM is smooth transition from straight to rotational movement.
An exaggerrated CBM is the basic of some specific dance moves, e.g., Chicken Walks in Jive and East Coast Swing.
