Henri Herz,
Contredanses variées, op. 35, is in the form of a quadrille, a complicated dance for four couples that has a set design of five numbers, each of which has a specific form. The first number has an eight-bar promenade, A (see below) followed by two dance "figures" with the musical design BACA, for a total of 72 bars: 8 + 32 + 32. As Franz Hünten does in a quadrille published around the same time (
link), Herz varies (embellishes) the return of B and C in the second figure, but never A.
At (a), a well-defined interval is unfolded; at (b), its lower note is extended; at (c), the unfolding reverses; at (d) a line descends from the upper note and at (e) ascends from the lower note.
