Habanera (music) in the context of Contradanse

The 1957 Encyclopédie Larousse defines a cell in music as a "small rhythmic and melodic design that can be isolated, or can make up one part of a thematic context". The cell may be distinguished from the figure or motif:the 1958 Encyclopédie Fasquelle defines a cell as "the smallest indivisible unit", unlike the motif, which may be divisible into more than one cell. "A cell can be developed, independent of its context, as a melodic fragment, it can be used as a developmental motif. It can be the source for the whole structure of the work; in that case it is called a generative cell."

A rhythmic cell is a cell without melodic connotations. It may be entirely percussive or applied to different melodic segments.

Danzón is the official genre and dance of Cuba. It is also an active musical form in USA and Puerto Rico. Written in
₄ time, the danzón is a slow, formal partner dance, requiring set footwork around syncopated beats, and incorporating elegant pauses while the couples stand listening to virtuoso instrumental passages, as characteristically played by a charanga or típica ensemble.

The danzón evolved from the Cuban contradanza, or habanera (lit. 'Havana-dance'). The contradanza, which had English and French roots in the country dance and contredanse, was probably introduced to Cuba by the Spanish, who ruled the island for almost four centuries (1511–1898), contributing many thousands of immigrants. It may also have been partially seeded during the short-lived British occupation of Havana in 1762. Haitian refugees fleeing the island's revolution of 1791–1804 brought the French-Haitian kontradans, contributing their own Creole syncopation. In Cuba, the dances of European origin acquired new stylistic features derived from African rhythm and dance to produce a genuine fusion of European and African influences. African musical traits in the danzón include complex instrumental cross-rhythms, expressed in staggered cinquillo and tresillo patterns.
