Capoeira (IPA: [ka.puˈej.ɾɐ]) is a Brazilian fight-dance, game, and martial art created by enslaved Africans during the 16th Century. Participants form a roda (circle) and take turns playing instruments, singing, and sparring in pairs in the centre of the circle. The game is marked by fluid acrobatic play, feints, subterfuge, and extensive use of groundwork, as well as sweeps, kicks, and headbutts. Technique and strategy are the key elements to playing a good game. Capoeira has three main styles, known as "regional", "Angola", and the less-well defined "contemporânea"
