Latin is a dance form with origins from the Cuban Son (circa 1920s) and Afro-Cuban dance (specifically Afro-Cuban Rumba). It is commonly associated with the salsa music style, although it may be danced under other types of music with an 8-count rhythm.
In many styles of salsa dancing, as a dancer changes weight by stepping, the upper body remains level and nearly unaffected by the weight changes. Weight shifts cause the hips to move. Arm and shoulder movements are also incorporated. The Cuban Casino style of salsa dancing involves significant movement above the waist, with up-and-down shoulder movements and shifting of the ribcage.
