The snare drum, called caixa in Brazil, has several variations depending on the style of samba. It consists of a metal barrel, two plastic skins and a tone that gives a special resonance to this Brazilian percussion instrument. The players use 2 wooden sticks. There is the caixa identical to the European snare drum to play Frevo (Recife region) and Samba Reggae (Salvador de Bahia region) and the snare drum from the Samba schools of Rio and São Paulo with a guitar string type timbre placed on the drumhead, therefore on top. The caixa is played on top "em cima" or on the bottom held by a strap like the military parade drums in Europe.
