Capoeira

An important part of Brazilian culture is the sport: capoeira(literally meaning, chicken coop).
Capoeira is a sport practice by people of all ages which mixes, music, singing, dancing, and martial arts. The instruments used are the tambourine, cowbell, a large drum, and a berimbau. The berimbau is a long pole that has a piece of thick wire stretched across it. At the bottom is attached a hollowed out gourd where the sound resonates. In one hand your strike the wire with a wooden stick while in the other you grasp the pole while hold a flat rock against the wire. As a result you get roughly a difference of a semitone depending on whether the rock is used or not. There are endless combinations of songs you can make just with that, and even more if you use 2 or 3 of the instruments. While the musicians play, everyone sits in a circle and sings and claps along. In the middle two people "fight" each other.
