A two-headed Brazilian drum used in samba baterias (percussion ensembles). It is equivalent to the tom-tom in the non-Brazilian drum kit or to the tenor drum in marching bands. It is tuned very high to produce a metallic tone that cuts through the sound of the rest of the bateria and it is a lead and solo instrument.

Typically its body is made of metal. The heads, made of nylon, are tightened through the use of metal tuning rods. The instrument is usually smaller in diameter than the Brazilian caixa (snare drum) but several inches longer in height and lacking a snare. It is carried using a shoulder strap attached to one of the tuning rods. In Rio-style samba it is played with one wooden stick and one hand, but elsewhere can be played with two wooden or plastic sticks.
