Isometrics are used to solidify the two-headed four-legged dance entity. There are Isometrics within each dancer and there are Isometrics within the partnership. Both are required to create the Ballroom Dance "Singularity".
Isometrics are defined as: "A system of physical actions in which muscles are used to act against each other or against another entity". In the case of Ballroom Dancing, we are talking about the connections within an individual dancer and the connections within a partnership. At the higher levels of Ballroom Dancing these two types of connections evolve into a Ballroom "Singularity" which prevails as the sole dance entity.
Ballroom Dancers generally start off as individuals then evolve into a partnership. Before the individuals can become a partnership, all kinds of evolution has to go on within the individual dancer. The evolution begins at the feet and works its way up through the body. The feet learn footwork, etc., the legs learn movement, etc., the hip area (core) learns Latin/Cuban motion, power, etc., the upper body learns frame, relative position, etc., and the head learns counter balance, direction, etc.
As the evolution continues, the individual dancer tries to incorporate all of these various individual elements. The problem is that the dancer's mind tries to do one thing, then the next, then the next, etc. As a result, the dancer executes one element, then another and another. The goal is to execute all of the elements at the same time. This is too much multi-tasking for the dancer. There must be a better way to be able to incorporate all of these elements to be executed simultaneously.
These elements are all physical actions. What if it would be possible to tie all of these elements into one physical feeling? Then simply execute (dance) that single feeling. Instead of trying to execute five different elements, a single physical feeling is executed. How is it possible to combine all of these elements into a single feeling? Ballroom Dance Isometrics is the answer.
How do Ballroom Isometrics work? Stand up and hold your arms up in a Ballroom dance frame (no partner). Drop your right arm down to your side. Be aware of how your left arm feels. Now, repeat with the right arm up and the left arm down. Again be aware of how it feels. This time hold both arms up and check the feeling. When both arms are up at the same time in dance position, you will feel a connection between your arms through the shoulders. The two arms have an Isometric connection naturally. The dance frame now has a single feeling. With both arms down, lift the chin and rotate the head slightly to the left. Now lift the arms up into dance position. You will feel the head position become part of the frame and still it is a single feeling (a new single feeling). While maintaining this position, rise on the balls of both feet. The feet now have an Isometric connection through the body to the dance frame, and yet another new single feeling. It doesn't seem like you are specifically making an Isometric connection. It feels like you are just allowing an Isometric connection and simply being aware of it.
This is just the beginning. Now connect all of these elements to the core of the individual dancer. All the physical parts of the individual can be connected in this manner. The goal is to have a single feeling for the whole individual dancer.
We have looked at the individual dancer's Isometric connections. Now let's look at the partnership's Isometric connections. The object is to combine two individual dancers together to create a single entity (a partnership, eventually a "Singularity"). This again is accomplished through Ballroom Isometrics.
Let's take the elements in the above physical exercise for the individual dancer and adapt them to a dance partnership using Isometrics. Create the dance frame as described above except this time with a partner. Notice that there is a natural Isometric connection to the partner. The frame connection now feels like an oval that includes the partner's frame. You don't have to do anything except be aware that it exists. Now be aware that the head position described above feels connected and directly opposite of the partner's head. Both heads can be connected by Isometrics to the oval partnership frame. Just as described above, connect the balls of the feet of both partners to the oval head-frame. Now, connect all of these elements to the core of the partnership. Notice that the core is not within either individual dancer. The single core is within the center of the partnership. Again the goal is to have a single feeling for the whole partnership.
Partnership Isometrics don't work unless both partners are participating. The goal is get the whole body, then the whole partnership involved in the movement of the Ballroom entity. Isometrics combined with Logical or Invisible connections allow the partnership to evolve into a true "Singularity".
