The undisputed king of the bateria, the surdo is the biggest and baddest drum of the lot. The surdo is the heartbeat of the samba, laying down the deep, resonant bass notes that are the foundation for the rest of the band to swing, groove and dance upon.

Needless to say, the surdo and its players command respect. It must be played with strength, confidence and at a rock-solid tempo for the rest of the band to function. Experience, stamina and a strong, steady tempo are required in order to play the surdo well.
