The siriá is a graceful folkloric dance from the state of Pará in the Amazon. It's danced by couples to the sounds of a flute, guitar, etc. and the strong percussion of large drums made of hollow tree trunks with both ends covered with leather. Men and women dance together and alternate on the dance floor. The siriá originated in the fishing communities along the river, as a sort of "courtship" dance. These populations, called "caboclos," are the biological and cultural result of mixed European, Indian, and African origins.
