Detailed instructions for lavoltas were written by Thoinot Arbeau; some brief notes appear in MS Douce 280. These instructions are open to some interpretation, but seem to indicate something like the following.
The dance begins with a galliard. Then the couple takes two bars of music to make a transition to closed position. The leader (the man, according to period custom) lets go of his partner's hand and takes hold of the front of her busk with one hand at or near the point, and places the other hand on her back above the far hip. The follower places her near hand on top of her partner's near shoulder. Now the leader is facing his partner while she faces to one side; both will do the turn with forward steps, and both step with the same foot at the same time.
The turn begins with a small step, springing onto the outside foot and lifting the inside foot forward. On the second beat there is a longer step, stepping smoothly onto the inside foot and staying close to the ground. During this step the follower poises herself for a spring, and just after it she springs up into the air. The leader lifts her with his hands, then holds her up with his hands and with the thigh of his free leg under her thighs. He lets her down to land on both feet on the last beat of the measure. The couple makes an approximate 3/4 turn during each measure. The turn is repeated ad lib for several measures, and then the galliard is resumed in an open position.
It is sometimes hypothesized that the lavolta was the direct ancestor of the waltz. Anyone who knows how to do a waltz turn may see from the above instructions (or from Thoinot Arbeau's instructions) that the dances are fundamentally different. The lavolta is more similar to the polska, though there again the differences remain large. The most that might reasonably be assumed is that the development of either the waltz or the polska might have been influenced in some way by the lavolta.
