With two persons, one has to imitate the movement of the other’s hand. In the first step, one is the leader and the other has to imitate. In the second step, roles are exchanged. In the third step, both players act as leader and follower, reacting and proposing at the same time.
With this exercise you can experiment with one non-musical exercise, feeling from a leader and follower. You can practice this in three interplay situations.
