Samba is a lively, rhythmic dance from Brazil with variations between regions. It originated in Rio de Janeiro and can be seen at Carnival celebrations. Capoeira began as an African fighting dance practiced secretly by slaves and later formalized as a martial art. Bossa Nova emerged in the 1960s as a slower, jazz-influenced dance but was superseded by other styles. Tropicalismo was an artistic movement that modernized traditional samba and bossa nova with political themes and rock influences.
