Samba (Portuguese pronunciation: [ˈsɐ̃bɐ] ) is a Brazilian musical genre and dance style, with its roots in Africa via the West African slave trade and African religious traditions, particularly of Angola and the Congo, through the samba de roda genre of the northeastern state of Bahia, from which it derived. Although there were various forms of samba in Brazil in the form of various popular rhythms and regional dances that originated from drumming, samba as a music genre is seen as originally a musical expression of urban Rio de Janeiro, then the capital and largest city of Imperial Brazil.
