Paso Doble or pasodoble is a lively style of dance to the duple meter march-like pasodoble music. It actually originated in southern Spain , but is modeled after the sound, drama, and movement of the Spanish bullfight. Paso doble means "double step" in Spanish.
A significant number of Paso Doble songs are variants of España Cañi. The song has breaks in fixed positions in the song (two breaks at syllabus levels, three breaks and a longer song at Open levels). Traditionally Paso Doble routines are choreographed to match these breaks, as well as the musical phrases. Accordingly, most other ballroom Paso Doble tunes are written with similar breaks (those without are simply avoided in most competitions).
Because of its inherently choreographed tradition, ballroom Paso Doble for the most part danced only competitively, almost never socially — or at least not without sticking to some sort of previously-learned routine. This said, in Spain, France, Vietnam, Colombia and some parts of Germany to the west of the river Rhine, it is danced socially as a lead (not choreographed) dance.
