What dance is that?

Maculelê is a dance from Africa developed in Brazil. When the leader gives the signal to begin playing Maculelê, two people enter the circle, and to the rhythm of the atabaque, they begin striking their own and each other's sticks together. On the first three beats, they strike their own sticks together, making expressive and athletic dance movements, and on each fourth beat, they strike each other's respective right-hand stick together. In some capoeira schools, students perform maculelê using a pair of machetes!
