Australian Wind Instrument (Trumpet): "Didgeridoo"

The didgeridoo, also known as a didjeridu or didge or as a "drone pipe", is a wind instrument of the Aboriginal groups, the indigenous Australians, of northern Australia. The didgeridoo is one of the best known primitive trumpets. It has been used among the Australian aboriginal people for at least 1500 years.

Authentic Aboriginal didgeridoos are usually made from hardwoods, especially various eucalyptus species in the region. It is usually manufactured from a trunk that has been hollowed out by termites. Craftsmen search for a correctly shaped trunk. Sometimes a native bamboo or pandanus trunk is used. The instrument is typically three to four feet long. It may be shaped like a cone or a cylinder. The bark is removed and may be painted or left undecorated. A rim of beeswax may be applied to the mouthpiece end. By vibrating his lips against the mouthhole, the player can produce a deep drone. The instrument is sometimes played by itself, but most often accompanies ceremonial dancing and singing. It is an integral part of ceremonial life among the Aboriginal groups. Only men play the didgeridoo and sing during the ceremonies, but both men and women may dance. The rhythm is established by a pair of clapsticks, or bilma.
