Argentine tango is basically a walking dance. Argentineans say if you can learn to walk, the rest is easy. They also say you have to "walk your miles" to learn to dance tango.
Walking technique:
As you apply the above technique in practicing walking (forward and back), keep in mind that you want to minimize any up and down movement. Roxanna described it Monday as "walking like a cat stalking its prey", or something like that.
Walk forward four-six steps, brush thru and reverse walking backward four-six steps.
Ochos:
Ochos ("eights") are a walking step as well. Instead of merely continuing straight forward or backward, however, you pivot as you brush thru (see above). How much you pivot in the actual dance will vary; for now a 90 degree pivot works. Walking technique is same for ochos, except when you brush thru you momentarily hold your foot (level-not with the heel raised) against your other ankle as you pivot. As you pivot and brush thru be careful that you don't momentarily put weight on the non-supporting foot, in effect pivoting briefly on both feet. The non-supporting foot can skim the floor, but all the weight remains on the pivoting (supporting) foot.
Ocho forward and back as in walking exercise. Also placing hands against and leaning toward and being supported by a wall, cabinet, etc., practice doing a series of forward ochos followed by a series of back ochos.
Grapevine:
A grapevine is a sequence of walking steps. Specifically a grapevine is a sequence of alternating forward and back ochos ("crossing" steps) interspersed with side steps. For example: 1) step on left crossing forward over right; 2) step on right sideways to the right; 3) step on left crossing behind right; 4) step on right sideways to the right, 5) etc. Again, technique for doing the grapevine is similar to doing ochos or walking steps, above. Having completed the previous step, you start the next one by brushing thru and pivoting; you then continue and complete that step by extending and shifting. The end of a step occurs, i.e. a step is completed, as you complete shifting weight from one foot to the other. A grapevine sequence can begin and finish arbitrarily. It can be 3 steps long, 18 steps long, 33 steps in length. It can move either left or right. It can begin with a side step, a forward crossing step (forward ocho), or a back crossing step (back ocho). When the woman is led sideways, either in a straight line, or in a curve as when the man leads her sideways around himself, she by default does a grapevine sequence of steps. This default is an important part of the syntax of Argentine tango. As in any language, syntax is crucial, and is essential both in communicating with your partner and in being able to improvise the dance.
Do grapevine sequences individually or holding hands with another person and moving in a tight circle. Doing it with another person you can place a chair between yourselves and grapevine around the chair. To further your enjoyment of this exercise you can try making a complete revolution around the chair in exactly four grapevine steps. Practice in both directions.
All of the above walking exercises can be practiced in two ways: 1) Robotically, doing the brushthru, pivot (if there is one), extension of the leg, and the shifting of the weight, in a very artificial, segmented fashion, focusing on each part of the step, maybe repeating that part several times back and forth before going to the next part; and 2) Flowing, liquid, as you would in the dance, making each part flow and blend into the subsequent part of that step.
Figures:
The only figures we looked at Monday was a salida leading to the cruzada, and then followed by a "tango close". Doing these in sequence repeatedly lead to doing a "box". I taught this poorly (or not at all) on Monday night, so I'm going to give a detailed description, along with my apologies and a promise to do better.
"THE BOX"
We mostly taught this as a choreography where the follower did her steps as the leader did his. In reality any figure, improvised or not, will be led by the leader and followed by the follower. This is just something to do to get started; like scaffolding in building a house. Don't take it too seriously. Use it as a sequence to practice walking with.
Practice "the box" both individually and with your partner. As you do your steps, try to simultaneously be aware of what your partner is doing. When practicing by yourself, adopt a phantom partner and be aware of what she/he is doing as you do what you're doing. Practice both roles (leader and follower) with your phantom partner (your phantom partner doing the opposite role.). When practicing with a real partner, try to "dance in their shoes/skin" as you dance in yours. This is a very productive exercise (when actually practiced).
Do all the above exercises with a partner focusing alternately (one thing at a time) on the frame (using different frames that we used in class), on the connection (establish connection and giving-of-weight before you take the first step), on brushing thru on each step (brushing thru is when the lead for the next step is initiated--we'll talk about this next week), and on what your partner is doing (which foot is she/he on, where is his/her weight, which direction is she/he moving in). The focus of the dance is primarily on the follower. In the beginning we say he focuses first not on his step but on hers; she focuses on him focusing on her.
