Start with feet, side by side, neither one in front of the other - a pie pari.
Reverse
The first tempo moves you a little way to the left, the second brings you back.
It's possible that the two balzetti are to be done to the left and then to the right, in the same tempo: I prefer going twice to one side in one tempo, then coming back in the next.
Other side:
Katherine Davies, 2016.
Two balzetti (little jumps) with even feet, to the side, with the campanella.
7. Duoi balzetti a pie paro per fiancho con la canpanella.
