The caixa is a snare drum made from a metal cylinder with a nylon skin at both ends and a string snare across the top of the playing end. The best caixas are made from aluminium. Caixas can be of various widths and depths; the standard sized caixa used in Rio baterias is 12" wide by 15 or 20cm deep.
TDSounds also sells the shallow-bodied snare drums known as tarols, and a dinky little 10" caixa for children, made to the same high specifications as all of our adult drums.
The caixa has a determining influence on the rhythmic identity of a samba band bateria, supporting the rhythm of the surdo with its fast, complex, repetitive rhythm.
