Son Urbano is the refined, city-shaped form of Son that emerged when the music traveled west from its birthplace in Oriente and took root in Havana during the first decades of the 20th century. The migration brought the rhythms, but the capital reshaped the dance.
Son originated among the montuno communities of eastern Cuba — Guantánamo, Santiago de Cuba — where it was danced in rural settings with a loose, relaxed posture and an intimate connection to the earth. When it arrived in Havana in the 1910s, it encountered a different social world: urban dance halls, clubs, and a middle class audience that expected something more presentable.
The result was not the abandonment of Son's African-derived rhythmic soul, but its repackaging within a more European social-dance vocabulary.
The urbanization of Son coincided with the rise of the sexteto (six-piece ensemble) and then the septeto (seven-piece, adding a trumpet). Groups like the Sexteto Habanero (founded 1920) and the Septeto Nacional de Ignacio Piñeiro (1927) professionalized Son performance and gave the music — and the dance — a new urban identity.
The trumpet brought brilliance and assertiveness to the sound. Dancers responded to this fuller, more forceful music with movements that could hold their own in larger dance venues.
According to EcuRed, the Cuban bourgeoisie detested the new genre, which found its followers in the working-class neighbourhoods and solares; the government even banned it, accusing it of immorality. But son soon gained ground, even in the most refined ballrooms, and record companies spread it widely. By the late 1940s, according to Wikipedia, son had lost its controversial status even among conservative Cubans.
