Now we're into the 2 basic theories of the molinete'... who is in charge?
I was taught that once the leader signals the start of the sequence and continues to invite the continuation of the sequence by how he uses his upper body, the follower sets the tempo and the step size (which needs to be determined by her ability to reach, not by his ability to pivot as the "maypole"). Clearly if the leader is doing a lapis or something, he can't provide much momentum or determine how she steps to the music, so she is providing the energy and setting the rhythm.
I truly hate when a leader tries to force me around in a molinete by "over-leading" the move. I can only reach around so far for a crossing back step and if he tries to pull me further, its not good. I'd have to break the CE parallel connection to pivot.
Also, I want to be using a logical tempo such as slow, quick,quick, slow (for side, back, side, front) and if he rushes me through the slows (which is what it feels like when he tries to "move" me through the steps, its pretty dern fast!
The leader can retake control at any point of the molinete to lead something else or create a specific tempo. But if he wants to just do a "normal" one, he should let her get on with it and not try to force it too much!
At least that's how I learned it. I know that some teach it as the leader being in charge of the whole thing, but then those leaders are unable to do a one foot pivot with decorations.
