"Rumba" is the word used for a group of related musical and dance styles in Cuba. (The word is also sometimes used to refer to a Latin-influenced ballroom dance style that is completely different than authentic Cuban rumba. Rumba can also refer to an African style of pop music developed recently with Latin influences.
Rumba developed in rural Cuba, with strong influences from African drumming and Spanish poetry and singing.
There are three basic types of rumba in Cuba:
Yambu - a slower, simpler style where older people and others dance in a relaxed manner
Guaguanco - a moderate to fast style where the rhythm can be more complex and a couple dances in a flirtatious fashion. The man throws his arm or leg or pelvis in the direction of his partner, symbolically attempting to touch or sexually contact the woman. She entices him and then turns away when he reaches out. The Spanish word "vacunar" refers to this moment, and comes from the term for vaccination.
Columbia - the fastest style, played in more of a 6/8 time signature and danced by solo male dancers who perform acrobatic and daring moves to demonstrate their courage, strength, agility, and sense of humor.
Grupo AfroCuba is a legendary folkloric group from Matanzas, Cuba. They are known as the originators of "Bata Rumba," and famed for their mastery of the full spectrum of Afro-Cuban folkloric music and dance.
