The didjeridu is a unique musical instrument found among the Aboriginal people of northern Australia. It is a straight trumpetlike instrument traditionally made from a termite-hollowed eucalyptus branch. The didjeridu is played by Aboriginal men to accompany clan songs and singing and dancing during ceremonies. A player inhales through the nose while blowing into the instrument (a method known as circular breathing) to maintain a constant drone. At the same time, a player may hum through the instrument to add a variety of sonic effects, ranging from rhythmic pulsations to imitations of animal sounds.
