The Los Angeles Salsa Style (LA style) is danced strictly on 1, in a slot (Line), using elements of various North American and stage dances. This helps prevent dancers from hitting other couples on a crowded dance floor. It is strongly influenced by the Latin Hustle, Swing, Argentine Tango, Mambo dancers from Mexico and Latin Ballroom dancing styles. LA style places strong emphasis on sensuousness, theatricality and acrobatics. The lifts, stunts and aerial works of today's salsa shows are derived mostly from LA style forms with origins in Latin Ballroom and Ballet lifts.

This New York style is danced in an ellipse or a "flat figure 8" on the floor, with the partners facing each other most of the time. Unlike other styles of salsa, New York style is danced on the second beat of the music ("on 2"), and the follower, not the leader, steps forward on the first measure of the music. The etiquette of New York Style is strict about remaining in the close dance space, and avoiding dancing in a sandbox area with many spins, turns and styling. There is greater emphasis on performing "shines" in which dancers separate themselves and dance solo with intricate footwork and styling for a time—a phenomenon that likely has origins from Swing and New York Tap.

Though he did not create New York style salsa, Eddie Torres is credited with popularizing it, and for having the follower step forward on the first beat of the first measure, followed by another step forward on the second beat to change direction (the "break step").

In Cuba, a popular dance known as Casino was marketed as Cuban-style salsa or Salsa Cubana abroad to distinguish it from other salsa styles when the name was popularized in the 1970s. Casino is popular in many places around the world, including in Europe, Latin America, North America, and even in some countries in the Middle East such as Israel. Dancing Casino is an expression of popular social culture; Cubans consider casino as part of social and cultural activities centering on their popular music. The name Casino is derived from the Spanish term for the dance halls, "Casinos Deportivos" where much 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, Cha Cha Cha, Danzón and Guaracha. Traditionally, Casino is 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. At the same time, it is often danced "a tiempo", although both "on3" (originally) and "on1" (nowadays).

Bachata is a style of social dance from the Dominican Republic which is now danced all over the world. It is connected with bachata music.
The basic steps of this pattern move side to side, changing direction after every tap. Characteristics of this "early" dance school dance is the close connection between partners, soft hip movements, tap with a small "pop" of the hip on the 4th step (1, 2, 3, tap/hip) and does not include many turns/figures.

Developed probably from around 2005 on the "western traditional" basic elements. The basics are the same as the "western traditional" dance, but with added dance elements and styling from Salsa, tango and Ballroom. In this dance, couples typically move their torsos more and greatly exaggerate the hip pop (especially the ladies). The most direct influence on the moderna dance comes from the adoption of salsa turn patterns; these, together with dips became the core of the dance.

The Sensual dance style was created in Cádiz, Andalusia, Spain, by Korke Escalona and Judith Cordero.
Korke learned the basics of western "traditional" in 1998, but with no more information than the basic step (four steps to the side) and inspired by bachata music, he started developing his own dance style inspired by contemporary and Brazilian zouk dances by understanding how the leader (traditionally a man) could lead the body of the follower (traditionally a lady) to interpret the music. The result is a novel, independent dance form with strict principles of leading and following, with mostly circular movements and body waves, but also body isolations and dips when the dancers feel the music calls for it

Brazilian Zouk is a partner dance which began in Brazil during the early 1990s. Brazilian Zouk evolved from the partner dance known as the Lambada. As the Lambada music genre went out of fashion, Lambada dancers turned to Caribbean Zouk (from the francophone, Caribbean Islands) as their music of choice. It was this transition that birthed the dance known as Brazilian Zouk. The term "Brazilian Zouk" was adopted in order to distinguish the dance style from the musical genre "Caribbean Zouk". Nowadays the term "Zouk" is commonly used to refer to the "Brazilian Zouk" dance style. The most characteristic feature of Brazilian Zouk is the follower's upper body movements which are led out of axis by intricate leading and following techniques. Other features include body isolations, tilted turns and more recently counter-balance techniques. Brazilian Zouk is a dance with well defined basic steps and rhythmic patterns. The representation of these steps and rhythmic patterns varies depending on the substyle of Zouk. The overall plasticity of the movements and the range of musical genres it is danced to, make Brazilian Zouk a partner dance that caters to creativity and improvisation. Over time, Zouk dancers have experimented and incorporated other styles of music into Zouk, such as R'n'B, pop, hip hop and contemporary (amongst others)

Semba has been danced in the 1950s in Angola. In the 1990s, when the actual kizomba music got more and more popular, Angolan semba dancers started to adapt their semba steps according to the tempo and flavour of the Kizomba beats. The Kizomba dance is a couple dance, in which the torso and right arm of the leader will guide the follower across the dance floor. It is the goal to synchronize perfectly as a couple with the music and express it through elegant footwork, smooth body movement and attitude, called Ginga (for women) and Banga (for men). Across the world Kizomba dance got mixed with other dancestyles such as Tango, HipHop, Latin Dances, Lambazouk, Acrobatics and more and created several major subcategories such as Kizomba Fusion and Urban Kiz.
