As in Brazil, the mandolin has played an important role in the Music of Venezuela. It has enjoyed a privileged position as the main melodic instrument in several different regions of the country. Specifically, the eastern states of Sucre, Nueva Esparta, Anzoategui and Monagas have made the mandolin the main instrument in their versions of Joropo as well as Puntos, Jotas, Polos, Fulias, Merengues and Malagueñas. Also, in the west of the country the sound of the mandolin is intrinsically associated with the regional genres of the Venezuelan Andes: Bambucos, Pasillos, Pasodobles, and Waltzes. In the western city of Maracaibo the Mandolin has been played in Decimas, Danzas and Contradanzas Zulianas; in the capital, Caracas, the Merengue Rucaneao, Pasodobles and Waltzes have also been played with mandolin for almost a century. Today, Venezuelan mandolists include an important group of virtuoso players and ensembles such as Alberto Valderrama, Jesus Rengel, Ricardo Sandoval, Saul Vera, and Cristobal Soto.
