Cuíca
Cuíca (Portuguese pronunciation: [kuˈikɐ]), or "kuweeca", is a Brazilian friction drum with a large pitch range, produced by changing tension on the head of the drum. Cuíca is Portuguese for a type of small opossum which is known to make a high-pitched sound. 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. Many also claim that the cuica has a "monkey" sound.
History
There are a number of styles of cuíca found around the globe. Its origins are disputed. Different sources trace it to Bantu slaves, to Spain, and to Muslim traders. It is also believed that the cuica was used in Africa as a call for the male lion since the sound mimics the roar of the female lioness. The instrument was introduced to Brazil by African slaves, where it found its place in Samba music.
Characteristics
The cuíca has a wooden stick fastened at one end inside the drum in the center of the drumhead. This stick is rosined and rubbed with a cloth. Changing the pressure on this stick produces the different pitches and timbres. The body of the cuíca is normally made of metal, gourd or synthetic material. It has a single head, normally 6 to 10 inches in diameter (15–25 cm), made of animal skin. A thin bamboo stick is attached to the center of, and perpendicular to, the drum head, extending into the drum's interior. The instrument is held under one arm at chest height with the help of a shoulder strap. To play the cuíca, the musician rubs the stick up and down with a wet cloth held in one hand, using the fingers of the other hand to press down on the skin of the drum near the place where the stick is attached. The rubbing motion produces the sound and the pitch is increased or decreased by changing the pressure on the head.
