The cuíca (Portuguese pronunciation: [kuˈikɐ]) is a Brazilian friction drum with a large pitch range, produced by changing tension on the head of the drum. Cuíca is Portuguese for the gray four-eyed opossum (Philander opossum) which is known for its high-pitched cry. The cuíca is frequently used in carnivals, as well as often in samba music. The tone it produces has a high-pitched squeaky timbre. It has been called a 'laughing gourd' due to this sound. The General MIDI drum kit provides cuíca sounds at the notes F♯5 and G5.
