Gennaro Magri's 1779 treatise,
Trattato teorico-prattico di ballo, one of the leading publications about dance technique from the 18th century, offers a rare view of the grotesque style of theatrical dance. One of the achievements of Magri's treatise is that is makes the argument for placing the
ballerini grotteschi on the same level of appreciation as
ballerini seri. According to Magri, false positions (inwardly turned) or Spanish positions (neutral in turnout) were more often used by
ballerini grotteschi, as opposed to the normative French
turned out positions. Magri asserts pirouettes on one foot, revolving for as many turns as possible, as part of the repertory of the
grotteschi, whereas pirouettes on two feet were for amateurs. He also links the
grotteschi's dance vocabulary with the cabrioles. One interesting such airborne step, ''salto dell'impiccato'' (translated as: hangman's jump) requires great elevation in order to create contrast between the trunk and the falling arms, and then a one-foot landing with the second leg detached into the air as much as possible. Magri assigns wrapping steps, sprung steps, steps of multiple turns, and airborne steps interweaving and beating the legs into the
grotteschi's repertory of movements. However, he makes the distinction that it is not these steps that make the
ballerini grotteschi, but rather the body as a "vortex of force" that articulates kinetic principles to get energy out into physical movement in a controlled and concentrated manner. The grotesque bodies are bodies that constantly concentrate and release energy as a characteristic part of their activity. ==Sources==
