The cuica is a friction drum with roots in African instruments brought to Brazil, where it became a staple of samba, carnival music and other Afro-Brazilian styles. Players rub a bamboo stick attached inside the drum skin to create its distinctive laughing, squeaking notes. Outside traditional music, short isolated cuica hits have circulated as sample pack sounds and soundboard clips, valued by editors who need a recognisable Brazilian percussion accent or a cartoon-like squeak without using a full drum pattern.
