I think of move possibilities like a drop-down menu on the computer, or perhaps a flowchart. My brain makes one decision at a time, and I dance a combination of moves that I often have not set up before-hand. Instead, at each "level" I make a decision, and that affects what happens next.

Level one: things that start on the outside

If I decide to move to the outside track, I often don't have a plan. I am just moving over/out there to see what might strike my fancy. Making my decision about what move to do is based on:

My follower: Whatever my follower does, right or wrong, in response to my move, helps decide what happens next. If they have good balance and alignment, I can do anything I want. If they tend to tip over right or left, that limits my choices.
Space: Do I have a lot of room in front of me? What about to my left? How close are the tables to my right? Where am I in my slot? How dangerous is the leader/couple in front of me?
Music: If I have plenty of space, I can let the music decide my movement choice.

Level two: right, left or straight ahead?

In the drop-down menu, this is my next level. I am on the outside, and need to pick. For my most recent session in my intermediates and up class (Portland, Oregon for those of you outside the area), we first learned several ways to get to the "outside" of the follower (to the follower's right when facing line-of-dance). Then, we explored different uses of the the space and how they work with tango, vals and milonga music.

I learned most of these moves dancing in Buenos Aires. For many of them, I first had someone use them on the dance floor, and then I took them to my teachers and asked how to lead it more clearly.

Back ocho across line-of-dance, then walk to the cross (zigzag to right)

Get to the outside track.
Take one step line-of-dance in crossed system (Leader's left, Follower's left).
Leader puts both feet down for balance, and turns Follower about 90 degrees.
Lead back ocho across line-of-dance: Leader steps side with right; Follower does back ocho with right.
Leader puts both feet down for stability, and turns Follower, ready to walk line-of-dance.
Exit in either crossed or parallel system: the Leader had both feet down, so it is easy to just push off whatever foot you want.

Variation with room for fun, big adornos (1 step straight, one right, one to return)

Same up to #3, then a change.

Get to the outside track.
Take one step line-of-dance in crossed system (Leader's left, Follower's left).
Leader puts both feet down for balance.
Turn the follower MORE THAN 90 degrees for the back ocho.
Lead the back ocho in this direction (slightly right back diagonal to line-of-dance).
Suspend the follower and let them adorn. Because the line of sight is clear, the Follower can decide to do something elegant, or something wild and crazy in the space.
Exit with FORWARD step for Follower and side step for Leader.
Turn follower in to regular embrace angle.
Exit line-of-dance.

Two kinds of circulos

I love circulos. I have been doing them since I first went to Buenos Aires in 1999 and learned them. I like how many walking steps can be fit into a small space by bending them into a pentagon or square, or whatever shape is made by that many steps. It FEELS like a circle, nice and smooth, but the straight lines of the steps make it crisp.

"Regular" circulo

This circulo is probably the one that I use the most. It is very compact, so it takes very little room. Because the follower is on the inside of the circle, it's easier to control the size of the move. I am fond of using it in the corners when other people forget to use them.

Get on the outside.
For each step of the circulo, angle the step just a little bit more than the step before. In other words, you have tiny pivots at the end of each step, making a 4-, 5- or 6- sided figure before exiting.
Don't forget your contrabody! It sounds counterintuitive, but I need to do regular walking, so I can't just have my chest face the follower and go around; that makes a messy circulo. Make each step a GOOD forward step, leaders!
The follower needs to know that each step is a BACK step. If you lose that clarity, the follower will start to do a giro (which is OK, but not what you planned).
If you walk correctly, it is pretty easy to finish the circulo, pivot your follower a bit, and walk out line-of-dance or to the cross, because you can return to the "inside" track at the end of any step of the circulo.

Jose's circulo

I am sure that Jose Garafolo did not invent this, but he is the one who taught me how to do this move well. There are only two differences between the regular circulo and this one:

The leader steps forward and then SIDE; forward and side, etc., rather than all forward steps. This means that you need to use your contrabody well to help you pivot. The follower still steps back on each step.
This is easiest to do by taking two steps (forward, PIVOT, side) and then turning the follower to face a new direction for the next chunk of the move. The follower often feels as if there is a six-step triangle or an 8-step square happening. I like the variation! Note: some people do this move in the same shape as the regular circulo.
When you are almost facing line-of-dance, pivot the follower so that you are facing line-of-dance and the follower is facing you; walk to the cross.

Scoop turn

I learned this move from Daniel Trenner, probably in my first weekend of tango. We did it in open embrace, but when I went to Buenos Aires, I found that it worked even better in close embrace!

Get to the outside.
Two steps line-of-dance: Follower takes two back steps. The leader takes a front step, pivots, and then takes a side step (same setup as for Jose's circulo).
Note: Leader must make sure to catch up with follower at this point, or the move won't work.
Leader plants both feet, facing towards the inside of the dance space, and then rotates the follower in a deep ocho (overturned ocho) to do a medialuna around to the leader's left: back, side, front.
Complete turn, pause (for adornos and balance), and then exit line-of-dance.

Marvin's favorite

My student Marvin came back from Buenos Aires completely in love with this move. It is a cross-system, counter-clockwise traveling turn on the outside, but I just call it Marvin's favorite. It has the same setup as Jose's circulo and the scoop turn, and is especially lovely in the vals.

Get to the outside.
Two steps line-of-dance: Follower takes two back steps. The leader takes a front step, pivots, and then takes a side step (same setup as for Jose's circulo).
Note: Leader must make sure to catch up with follower at this point, or the move won't work.
Leader tucks left leg behind into an enrosque, and pivots on BOTH feet around to face line-of-dance (or as close to that as works at the moment). Follower is led to step forward around leader, then side step (2 steps of a left turn).
[Optional] If the pivot did not go very well, and the follower ends up on the outside track, the leader can just exit here.
[Optional] If the pivot went OK, but not great, the leader will need to suspend the follower, and shift to the outside again before repeating the step.
Do the same move a second time if you have room.
Exit to the cross.

Calesita

There are many versions of calesita that work well on the outside. Here are a few suggestions:

Do a circulo (1/4, 1/2 or full), and then suspend the follower and do a calesita around them until you are facing line-of-dance. Exit.
Do the scoop turn preparation, but instead of doing the turn, suspend the follower and do a calesita around them at this point.
Do a circulo, then a calesita, then another circulo. This was a favorite for Tete during the time I studied tango vals with him in Buenos Aires in 2000. It flows as only Tete could.
Do a calesita after one of "Marvin's favorite" turns as a fun ending if you have a partner who has good balance.

Boleo

You can add a boleo to either the zigzag back ocho, or at the point where you would have done a scoop turn/calesita/Marvin's favorite; and exit.

Level three: exit!

The drop-down menu on whatever move I am doing has one more level: getting out. I have a few tried and true basic things that I do here, again based on space, partner and music.

Walk to the cross: get back on the follower's right (regular or inside, depending on your dance). It's in a straight line down the dance floor, and familiar to the follower. No complications.
Move line-of-dance and worry about moves later. If I have space in front of me, I will do some walking variation to keep traffic flowing.
Do another one! Especially in vals, if the flow of the dance is working well and I have room, I might do a second (for turns MAYBE a third) iteration of a move, as long as it moves a bit forward. I do that less in tango.

Truth be told, I rarely think this far ahead when I dance. I am happy to have reached the stage where my body often picks a move for me. I don't think very much while dancing. It took me a long time to get here, as I am the kind of geek who thinks about movement all the time. Do the rest of you try to analyze what muscles you are using while you weed your garden? Probably not. :-)

Your turn!

Now, use these ideas for practice, and then go out and dance and see what happens organically. Let me know what else YOU like to do when dancing on the wild [out]side!
