This treatise includes six solo dances for women; eight for men; and seventeen duets for a man and a woman, two women, or two men, all choreographed by French dancer and choreographer, Guillaume-Louis Pecour (c. 1653-1729). Feuillet notes that several of the dances were performed by some of the most famous theatrical dancers of the time including Marie-Thérèse Subligny, Claude Ballon, and Michel Blondy. Many of the dances originated in the operas of Jean-Baptiste Lully including Ballet des Fragments, Persée, and Cadmus et Hermione as well as Trancrède and L'Europe Galante by André Campra. The dances are notated in a system first published by Feuillet in 1700 and based on tract drawings that trace the pattern of the dance. Additionally, bar lines in the dance score correspond to bar lines in the music score. Signs written on the right or left hand side of the tract indicate the steps.
