An upper-voice wedge in a contredanse gigue (1781)

One of the clearest examples of a wedge figure in a three-voice texture can be seen below. The handwritten title is "Les Caprices de Galatée," which may or may not refer to a Parisian dance-pantomime of that title. This is the 17th page in volume 3 of the collection The celebrated Dances performed by Messrs. Vestris &c. at the King's Theatre in the Hay Market, 1781, composed by G. B. Noferi. Link. Giovanni Battista Noferi was an Italian violinist (he also played guitar) who apparently came to England early and stayed, working mostly in London. He died in 1782, the year after this collection was published. The Vestris were a large French family of professional dancers.

Very plainly a contredanse gigue, this piece is cast in the very common design of three strains (ABC) and five sections en rondeau (ABACA). All three strains are simple period themes. Indeed, the design is so familiar that amateur dancers would have no trouble dancing to it, either in the four-couple quadrille formation or as a long dance.

The principal strain has a stationary voice on E5, which the surrounding voices approach in a wedge, the "alto" voice reaching the tonic note, the upper voice making it part-way to G#5 (^3) but losing even that in the consequent. As readers of this blog will know, this strong implication of a pitch not actually sounded in the cadence is a common device, especially in violin music, and one can readily imagine it as an inducement to particular figures in ornamented repetitions (see below the score for one obvious such figure here).  For more on complex upper voices, see this essay of mine: link.

A likely (actually, almost inevitable) cadence figure improvised in performance:
