Puerto Rican style
This style can be danced as "On One" or "On Two". If danced as "On Two", it is always danced on count 2, and not on count 6 as in Ladies-style NY. There is a Salsa Congress in Puerto Rico where salsa groups all around the world attend and perform.
Rueda style
Rueda de Casino. In the 1950s Salsa Rueda (Rueda de Casino) was developed in Havana, Cuba. Pairs of dancers form a circle (Rueda in Spanish), with dance moves called out by one person. Many of the moves involve rapidly swapping partners. In the Philippines 2005, a growing interest among young Filipinos led to a fusion of salsa and community dance, later called Ronda de Salsa, a dance similar to Rueda but with salsa dance moves that were choreographed locally and in Filipino names. Among the popular calls in Ronda were: Gising, Pule, Patria, Dolorosa, Lakambini and La Antonio.Salsapower Editorial: Ronda de Salsa
Salsa Styling
Incorporating styling techniques into any style of salsa has become very common. For both men and women shines, leg work, arm work, body movement, spins, body isolations, shoulder shimmies and rolls, and even hand styling have become a huge trend in the salsa scene. There are lessons dedicated to the art of salsa stylin'. Hip hop, jazz, flamenco, belly dancing, ballroom, breakdancing/pop and rock, Afro Cuban styles, and bhangra have all be infused into the art of styling. You can take dance lessons to learn all these different types of dances.
Shines
Normally Salsa is a partner dance, danced in a handhold. However sometimes dancers include shines, which are basically "show-offs" and involve fancy footwork and body actions, danced in separation. They are supposed to be improvisational breaks, but there are a huge number of "standard" shines. Also, they fit best during the mambo sections of the tune, but they may be danced whenever the dancers feel appropriate. They are a good recovery trick when the connection or beat is lost during a complicated move, or simply to catch the breath. One possible origin of the name shine is attributed to the period when non-Latin tap-dancers would frequent Latin clubs in New York in the 1950s. In tap, when an individual dancer would perform a solo freestyle move, it was considered their "moment to shine". On seeing Salsa dancers perform similar moves the name was transposed and eventually stuck, leading to these moves being called 'shines'.
