The berimbau is a musical bow of African origin that became central to Brazilian capoeira, where a player leads the roda by setting the tempo and style of play for the two players in the circle. Traditionally made from a wooden bow, a steel string and a dried gourd resonator, it produces different tones when the player presses a coin or stone against the string. As capoeira spread from Brazil to schools and performances around the world, its distinctive twang became a shorthand for Brazilian culture in dance, sport and documentary footage.
