I will attempt to explain my perception of what constitutes leading in a dance. Let me first quote the definition that I once read in a book about leading: To lead is to have a vision, to communicate this vision, to plan for the execution of this vision and to follow through the execution of this vision. Am I making things more comnfusing? Let me try to illustrate this definition:
1. One must have an a priori (that is, an ahead of time) vision of the dance move to perform. This vision must accommodate the specific rules of a dance style. In other words, if the leader tries to place his partner some place on the dancing floor without accounting for which one of her feet is expected to move at any given time, the leader may induce the follower to trip and fall! You would not want to do that to any partner; they would not want to dance with you any more.....So, this vision (the move you intend to perform) must be already proven and to work well before attempting it with a partner. It must be carefully planned.
2. Once you have developed a doable (both for you and your partner) vision of the move to perform (that is you have developed the plan), the next step is to communicate this vision to your partner. In dance, the communication is mostly through touch, but also visual. To be able to communicate well with your partner you need to do the following things:
a) Make sure that you provide a frame of reference to your partner. That is, your arms must maintain a certain rigidity which defines the space in which your partner should be located at all times. Your ability to maintain that frame (without collapsing your arms) is for the most responsible for the success of your lead. Of course, your partner must also cooperate, and offer you a corresponding rigid frame (no collapsing of her arms is allowed) which should remain interlocked with yours, so that any light pressure of your frame to hers will be felt by her and induce her to move in the direction you want to move.
b) Anticipate: This means that the pressure from your frame to your partner's frame must at all times and with continuity be exercised ahead of the move which is taking place. In other words, when you are executing the dance move, your frame moves slightly ahead of the music's tempo, while your partner is moving on the beat of the music. In common words: You dance ahead of the music; she dances with the music.
3. During the execution of the dance move, you must at all times check that your partner is following appropriately. You do this by constantly feeling the response of your partner's frame to your's. If your partner does not seem to follow very well, you might need to slightly increase the pressure of your frame on hers, to make your intentions more clearly understood. Be gentle! No lady likes to be pushed around.....
A few tips on how to learn to lead:
1. Make sure you know your own steps so well that you do not have to think about them. Once you are able to perform your own steps instinctively, you will be able to devote your attention to holding your frame and, with it, guide your partner.
2. NEVER collapse your frame, even if your partner happens to do so!
3. Dance a lot, and with different partners. Each lady will feel different, and follow differently. It is your responsibility to provide for the needs of your partner.
A final word on visual leads: Once you develop a lot of experience, you can suggest to your partner future moves way ahead of the one you are executing. The visual leads can be as simple as a sway of the body and as complex as a change in the direction of your eyes. Visual leads must be perceptible to your partner, but should remain unnoticed by the spectators.
I hope this helps. Cheers!
