The Surdo is a double-headed drum played with a large padded baqueta (beater). Players muffle the sound with their hand for one beat, and then the second beat is accented. The Surdo provides a two-four rhythm. When more players are added, several surdos are used.
The Pandeiro is the national instrument of Brazil. It is the equivalent of the tambourine; the frame drum is single-headed and pratinelas (jingles) are loosely arranged in pairs around the instrument’s side. The Pandeiro produces a stream of semi-quavers (1/8 notes). Each are distinct and they are produced by the player’s unique playing technique. It is good for samba in small groups.
The Cuica is another percussion instrument used in creating Samba. Pronounced 'qweeka', it makes an unusual sound that resembles a monkey laughing. You play the cuica by rubbing a stick inside the shell of the drum with a wet piece of paper or cloth. The Cuica musician presses on the drum's head simultaneously to change the pitch.
These are 'jingle' shakers that produce different sounds; they contribute to the samba swing.
This small double-headed percussion instrument is tuned very high. It is played with one stick and the player's hand. You can also use two flexible plastic sticks. It leads the bateria, signaling breaks and cues.
