Samba Schools Parade, Rio de Janeiro carnival, Brazil - cuica, musical instrument, samba band. Cuíca or "kuweeca", is a Brazilian friction drum with a large pitch range, produced by changing tension on the head of the drum. It is most often used in samba music. The tone it produces has a high-pitched squeaky timbre. It has been called a 'laughing gourd' due to this sound.
