An Angola roda will usually commence with a ladainha (litany), often sung by the most senior member present. These songs may be improvised on the spot, but are often famous songs written by an earlier mestre. Mestre Bimba removed the ladainha from his game of Capoeira Regional, replacing them with Quadras, mini-solos with verses composed of 4 to 6 lines. Once either the ladainha or Quadra has been sung, the same singer will usually sing the chulas or louvação, which again may be improvised on the spot. The chorus repeats each line of the chula after it has been sung. Finally, corridos will be sung while the game is playing. In most rodas anyone can sing a corrido, though most often they will be sung by the members of the group playing instruments, the bateria. Various kinds of despedidas, or "goodbyes," are sometimes sung to end the roda. Often, these are accompanied by a ritualistic procession, begun by berimbau gunga. Participants may stand and walk in a circle, at which time it is permitted to comprar o jogo (or "buy into the game"). The procession may also leave the space in a single file, passing the gunga player (usually the mestre) as they exit. The only instrument that remains stationary is the atabaque. At other times, a roda may end with the toque de samba, after which a samba circle erupts.
