Standard Technique: CBM versus CBMP

CBM, or Contra-body Movement, is a rotation of the body. It is used to set up body position subsequent steps. CBMP, or Contra-Body Movement Position, is a step. In a figure such as the Feather Step in Foxtrot, CBM on the first step on the right foot sets up the correct relative position of leader and follower so that the followers steps in CBMP on the second step, and the leader steps in CBMP on the third step.
