There are lots of ways to be beautiful and elegant as a Revel, and you should find your own special style…. These are a few of Vio’s favorites:
Make a Beautiful Projection
The only difference between ballet and tango projection/tendu, is that in tango the free leg is relaxed with the knees touching, slightly nested so that the free leg’s knee is either a little in front or behind the base leg. We always transfer weight onto an externally rotated projected foot so that the leg muscles will be in the optimum position for smooth and supple movement.
Point Your Toes when in the air.
This has gone out of fashion, but I still like it. To point your foot in a tango shoe is harder work than pointing it in a ballet shoe, so we have to be strong!
Here are some videos with exercises:
In front steps, Transfer to a pointed Toe
The hard work of the base leg makes it possible to transfer directly to the free leg’s toes. There are three actions that I do with my old base leg:  maintain hip flexion  knee extension (makes it easier, but not necessary)  ankle extension, which means that I will methodically go from a flat foot, to demi-point (arching the middle of the foot while keeping the ball of the foot on the floor), to full point (contracting the toes and the arch and fully extending the ankle to complete the transfer of weight).
There are different issues for each leg, as always caused by the embrace. When You are stepping from right to left, you are often in a front ocho and the mark is pushing on your back. You have to use extra hip flexion in order to maintain your base long enough to move in the way you want. When you are taking a front step from left to right, you are moving into the closed side of the embrace, and you must work extra hard to externally rotate your base leg so that the muscles can work.
Our legs look beautiful when we extend the knee fully early in every projection.
In addition, it looks sexy in front and side steps to extend the base leg’s knee as early as possible in the transfer.
