Summarize:

In American style tango, progressive rocks are where you rock back and forth moving your weight from foot to foot instead of taking a step. So in the basic step we talked about, instead of quick, quick being two steps in one direction, it's one step and then rocking your weight forward. Clear as mud, yeah? If you're leading, you're taking a two steps forward on quick, quick. Instead, take one step forward, and then throw your weight back onto your back foot (without moving it). If you're following, it's the opposite: step back on quick, and then move your weight forward on the second step. With progressive rocks and cortes, you can get two moves in one. The corte is the same as a progressive rock but on the first two steps (slow, slow). To give it more oomph, make sure your strides are long and fluid. Now have you and your partner facing the side -- this is called the promenade. Instead of thinking forward and back, you're thinking to the left or right. This way you can add in swivels and turns. In most tango forms, the follower (or woman) does most of the dirty work, but men can get in on the action, too! Let's say, as partner B, you take two steps to the right (slow, slow). Immediately after that second step (and before the third), throw your torso to face the left. Then you resume moving backward. Swivel check! For turns, the leader turns toward his partner 180 degrees on the first quick step and the one following steps between his feet. Now we're getting fancy! It would seem like leading is easier -- being able to read someone's mind is no easy feat -- but leading has its own perils, too. You always have to plan a step ahead and know where you want the dance to take you. So while you're working your way around the circle, think 8 steps into the future. You get to have the peace of mind that you just have to go with the flow. But going with the flow can be a little disconcerting if you don't trust. The easiest way to know that you're capable of depending on your partner is to feel their weight. Feel where it's going. Feel where it is between the moves. Balance with them. It'll take you with it. You can do all the fancy moves you want, but if you and your partner don't have that synchronicity, that gel, that essence is the tango, it doesn't matter. Don't feel pressured to spice it up. Stick to what you feel. Keep it simple, master the simple, and the rest will come. Have you ever seen an old couple that just walks a simple dance together? How moving it is because you can see how they just get it? That. That is what you're aiming for.
Try progressive rocks. Corte. Add swivels and turns. If you're a leader, plan ahead. If you're following, feel your partner's weight. Know that there's beauty in simple.
