According to Wikipedia;
The berimbau (Portuguese pronunciation: [beɾĩˈbaw]) is a single-string percussion instrument, a musical bow, from Brazil. Originally from Africa where it receives different names, the berimbau was eventually incorporated into the practice of the Afro-Brazilian martial art capoeira, the berimbau (the soul of capoeira) leads the capoeiristas movement in the roda—the faster the berimbau is playing the faster the capoeirista moves in the game. The instrument is known for being the subject matter of a popular song by Brazilian guitarist Baden Powell, with lyrics by Vinicius de Moraes. The instrument is also a part of Candomblé-de-caboclo tradition.

Each one of these religions from Africa has it's own peculiar rhythms. How they have survived intact over hundreds of years under unique circumstances is a mystery.
