The joropo is a musical style resembling the fandango, and an accompanying dance. It originated in Venezuela and is also present in the eastern Colombian plains. It has African, Native South American, and European influences. There are different joropo variants: tuyero, oriental, and llanero. It is a fundamental genre of Venezuelan música criolla (creole music). It is also the most popular "folk rhythm": the well-known song "Alma Llanera" is a joropo, considered the unofficial national anthem of Venezuela. In 1882 it became Venezuela's national dance and music. Formerly, the Spanish word joropo meant "a party", but now it has come to mean a type of music and dance that identifies Venezuelans. In the 18th century, the llaneros started using the word joropo instead of fandango, which was used at the time for party and dance. Central joropo (joropo central) is also known as tuyero ("Tuyan"), joropo tuyero ("Tuyan joropo") or golpe tuyero ("Tuyan beat"). Characteristic of the central states of Venezuela, like Aragua and Miranda, eastern Carabobo and northern Guárico, central joropo, or tuyero (as practiced in the Valles del Tuy along the Tuy River) is sung accompanied by harp (arpa tuyera, sometimes replaced by guitar) and maracas. Unlike the nylon strings of the llanera harp, the central joropo harp also uses metal strings, which gave its unique sound. The central joropo singer also plays the maracas and dances, requiring just two performers: the harpist, and the singer-maraquero. Joropo harpists prefer the name "arpisto" rather than arpista, the usual Spanish word for "harpist". The central joropo him the same considerations are applied around the passage and hit burrowing joropo, except speed, which is slightly lower. Another important distinction is that the central joropo revuelta, kind of colonial origin is present, basically consists of a chain of musical sections of fixed forms, in the same tone as a Baroque suite, without interruption, but with surprising twists.
