Five Ceremonial beaded Flutes or Whistles from the Cameroon Grassland.They come in a variety of geometric form, taking on the shape of a hollowed, stylized figure that combines human and animal features. Most have a hole or some device for the attachment of a carry strap in string, cloth or leather. Mouthpiece up the flutes resemble buffalo heads; hanging inverted they suggest the human form. Whistles are usually tuned to play up to three notes and may be used alone or played in sets to produce a scale. Sound is made when a player blows air across a sharp edge - in this case between the crescent-shaped ends. This globe has a height of 45 cm.
