SALSA CUBANA & TIMBA

In Cuba, a popular dance known as Casino was marketed abroad as Cuban-style salsa or Salsa Cubana to distinguish it from other salsa styles when the name was popularized in the 1970s. Dancing Casino is an expression of popular social culture; Many Cubans consider casino a part of their social and cultural activities centering on their popular music.
The origins of the name Casino are casinos deportivos, the dance halls where a lot of social dancing was done among the better off, white Cubans during the mid-20th century and onward.
Historically, Casino traces its origin as a partner dance from Cuban Son, fused with partner figures and turns adopted from the Cuban Mambo, Cuban Cha Cha Cha, Rumba Guaguancó and North American Jive. As with Son, Danzónand Cha Cha Cha, it is traditionally, though less often today, danced a contratiempo. This means that, distinct from subsequent forms of salsa, no step is taken on the first and fifth beats in each clave pattern and the fourth and eighth beat are emphasised.

In this way, rather than following a beat, the dancers themselves contribute in their movement,to the polyrythmic pattern of the music.
What gives the dance its life, however, is not its mechanical technique, but understanding and spontaneous use of the rich Afro-Cuban dance vocabulary within a Casino dance. In the same way that a sonero (lead singer in Son and Salsa bands) may "quote" other, older songs in their own, a Casino dancer frequently improvises references to other dances, integrating movements, gestures and extended passages from the folkloric and popular heritage. This is particularly true of African descended Cubans. Such improvisations might include extracts of rumba, dances for African deities, the older popular dances such as Cha Cha Cha and Danzón as well as anything the dancer may feel.

Timba is a Cuban genre of music based on Cuban son with salsa, American Funk/R&B and the strong influence of Afro-Cuban folkloric music. Timba rhythm sections differ from their salsa counterparts, because timba emphasizes the bass drum, which is not used in salsa bands. Timba and salsa use the same tempo range and they both use the standard conga marcha. Almost all timba bands have a trap drummer. Timbas also often break the basic tenets of arranging the music in-clave. Timba is considered to be a highly aggressive type of music, with rhythm and "swing" taking precedence over melody and lyricism. Associated with timba is a radically sexual and provocative dance style known as despelote (literally meaning chaos or frenzy). It is a dynamic evolution of salsa, full of improvisation and Afro Cuban heritage, based on son, Rumba and mambo, taking inspiration from Latin jazz, and is highly percussive with complex sections. Timba is more flexible than salsa and includes a more diverse range of styles. Timba incorporates heavy percussion and rhythms which originally came from the barrios of Cuba.
