Beginning with the left foot behind, in passo naturale, raise the left per fianco, about half a palm from the right, and with the left do a cadenza a piedi pari. That done, give a sottopiede with the left per fianco to the right, and raise the right per fianco, about half a palm from the left. This can also be done on the other side, and also beginning with even feet. It is so called because it is done per fianco.
