- Era: 1880s-1890s (America)
In his sizable manual of couple dance variations, Round Dancing (Portland, Maine, 1890), late 19th-century dancing master M.B. Gilbert describes the Waltz-Galop succinctly as:
Waltz step, Galop time
While no other dancing master that I have found includes the waltz-galop by name, the accenting of a waltz step done in duple rather than triple time is discussed by Allen Dodworth in Dancing and its relations to education and social life (1885, reprinted several times through 1900) and is included in dances such as the turn-of-the-century Pasadena, and the idea that waltz steps can be transposed from triple to duple and vice-versa dates back as far as the sauteuse waltz of the first quarter of the 19th century.
