Colombian music is a combination of African, Indigenous and Spanish influences mixed with modern American and Caribbean musical forms. The national music of Colombia is narrowed in two forms, the vallenato and cumbia. Cumbia is a mixture of Spanish and African styles, which was said to be brought by slaves. The music of Colombia is meant to be danced from the poems and stories of their history. In these groups the musicians will include singers, tiple, a requinto and guitar. New styles arose as more ethnic groups began to mix creating musical styles of bambuco and porro. A similar style of the waltz became popular in the 19th century of Colombia called pasillo. The most popular Latin stars including Mana, Shakira, Charlie Zaa and Joe Arroyo made this style very popular.
