Kuisi

A kuisi (or kuizi) is a Native American fipple (or duct) flute made from a hollowed cactus stem, with a beeswax and charcoal powder mixture for the head, with a thin quill made from the feather of a large bird for the mouthpiece. Seagull, turkey and eagle feathers are among the feathers commonly used.

There are male and female versions of the kuisi (or gaita, the Spanish for pipe). The female kuisi bunsi (also rendered kuisi abundjí in Spanish ) is also commonly known as a gaita hembra in Spanish, and has 5 holes; the male kuisi sigi (or kuisi azigí) is called a gaita macho in Spanish and has two holes.

Players often use wax to close fingerholes and alter the sound of the flute, blocking one or other tone hole on the kuisi sigi, and on the kuisi bunzi either the upper or lower fingerhole so that only four holes are in use at any one time. The change of wax from one fingerhole to another alters the fundamental tone and series of overtones that can be produced. A photograph of the paired flutes of the Cuna Indians of Panama shows that their hembra has only four fingerholes.

Modern Kuisis are between 70 and 80 centimetres long, a length traditionally defined by the arm length of the luthier. Kogi built kuisis are reported to be up to two feet, or 60 centimetres, long. and constructed from cane (carrizo) by the flautist himself (never a woman). The length being measured as 3 times the span between extended thumb and little finger plus the span between extended thumb and index finger. The holes are then located with a distance between them measured by the width of two fingers plus half the width of the thumb. They are constructed from a cactus (Selenicereus grandiflorus) which is bored and whose thorns are cut. The center is removed, first moistening and then boring with an iron stick. The cactus stem is thicker at one of its ends, this will go upside and coupled with the bee wax head which carries the feather mouth piece. Though the instrument is slightly conic on the outside, its perforation is cylindrical.

The kuisi bunsi has five tone holes, but only four of them are used when performing: the lower tone hole is rarely used, but when used, the upper tone hole is closed with wax. The lower tone hole of the kuisi sigi is rarely used.

The instrument’s head, called a fotuto in Spanish, is made with bee wax mixed with charcoal powder to prevent the wax melting in high temperatures, which also gives the head it a characteristic black color. The mouth piece, a quill made from a large bird feather, is encrusted in this bee wax-charcoal head, with an angle and a distance to the edge of the air column which varies from instrument to instrument.
