The contradanza was the first European dance that truly became Cuban: under African influence it grew into something of its own. It is the starting point of the Cuban salon dance lineage that would eventually produce danzón, mambo, and cha-cha-chá.

Even in its earliest Cuban form, the contradanza was already different from its European source. Cuban musicians gave it the habanera rhythm: a bass pattern with a dotted first note (DAAM-da-DUM-DUM), closely related to the tresillo (long-long-short, 3+3+2) that also sounds in Afro-Cuban music. It gave the music its characteristic, gently swaying feel. The rhythm became so associated with Cuban music that it traveled the world: you can hear it in Bizet's Carmen, in early tango, and in countless 19th-century popular songs.
This was African influence at work: not explicit, not acknowledged by the salon class, but present in the bones of the rhythm. That is less strange than it seems: the musicians who played at the balls were largely Black and mulatto musicians. Music was considered a trade for the lower classes, and through their hands the African rhythmic feel entered the salon.
Contradanzas were mostly written for piano, but in the ballroom an orchestra played them. The last tab shows what Irakere made of one a century and a half later.

Contradanza was a group figure dance: formal, indoor, with couples in rows or a square and a bastonero (dance leader) calling the figures. It was a social activity for Cuba's literate class: plantation owners, merchants, professionals, and their families.
Despite that formality, Cuban dancing was already looser in the hips and more rhythmic than European ballroom. More about the steps and figures is on the dance page, about the music on the music page.
The contradanza travelled a long way before it reached Cuba:
In Cuba the dance soon began to change. The oldest known Cuban contradanza, the anonymous San Pascual Bailón, was published in 1803.
By the 1820s–1840s, contradanza was the dominant popular dance of Cuba's educated and upper-middle classes.
Contradanza established the two-part form (an A section and a B section with a rhythmic change), the habanera feel, and the salon dance tradition that ran through danza and danzón into every later Cuban dance. The danza then took the step towards couples dancing on their own; the danzón completed it. It planted the seed of African rhythmic transformation that would later fully bloom in son and timba.
