The demi-plié is almost isometric. In both the downward and upward movements, the feet—rather than the knees—should initiate the movements. The feet grip the floor and pull the legs into the plié and then relax and push down to return the legs to the standing position. This also applies to pliés on one foot.
Most dance movements are on one leg. What must be developed at the barre is the ability to balance on and move from one foot. Try to work at portable barre placed parallel to the mirror. Stand behind the barre, on the diagonal. This will allow you to keep an eye on your supporting side and encourage you to work correctly. Test your balance by frequently taking your hand off the barre during exercises. In addition, check your readiness to move. You should always be able to rise off your heel whenever you press down on the floor.
The supporting leg controls the free leg, and initiates each movement. The timing of every movement is made by the supporting leg. The free leg (the foot that brushes or slides) never pulls or moves the body. Only the supporting foot that pushes the floor should move the body.
In the center floor, every step you take must be balanced by an arm, or both arms, reaching in the opposite direction. At the barre, develop this sense of the “back arm” by reaching for the barre and pressing down it. Never pull on the barre.
When you pirouette from the fourth position, be sure that you go to “the end of theplié.”
A jump is a relevé in the air. Push the floor, stand in the air.
Overcross the glissade précipitée, which leads into battement fondu developpé relevé, and jumping steps where the free leg is brushed into the air.
