In a tango embrace, the follower practices the turning system steps around the leader. (this is unled, the follower can chance the turn direction or speed in any moment)
The leader reports which type of step she is making in each moment (back, side, forwards)
Repeat with the leader’s eyes closed
Further:
Leader can make a light contact between his free foot and the new standing leg of the follower to confirm her location
Leader locates her front step and leads a parada with direction change, follower passes in the new direction and continues to practice.
