Standing with the left left foot behind, in passo naturale, as shown in the figure above, separate the knees a little, and lower the body in the manner of a reverenza, then jumping about four inches from the ground, return to the ground with the whole body [con tutta la vita - meaning you land on both feet?], and place the left foot where the right heel was at first, and the right foot a little more in front, in passo naturale. This can also be done per contrario, and it is so called because you jump forwards, like a bouncing ball [balzo di palla].
