Some moves (I'll talk about Salsa, but idea should be the same for most other dances) can be led without follower knowing the exact move. But for some moves, I would think the follow needs to know the mechanics. I was practicing with my partner, and I was showing you one of those moves. And she asked - what's the point for you (me) to learn this move - if you can't teach it on the dance floor, you won't be able to use it. Unless the person you are dancing with already knows it. But how do you know if she does? So, the question is: how do I know the follow knows the move I want to lead? And a more open ended question - how do I approach this whole situation? I am excited about this, because I am about to gain new insight into the world of dance.
