A simple aerophone woodwind that uses the lips as the reed, constructed of a large tube of eucalyptus wood or bamboo.

One of the oldest musical instruments in the known world, with estimates ranging from 10,000 to 80,000 years. Originating in northern Australia, it started to become more widely known in the 1960s and 1970s.

A didgeridoo is made by taking a suitable limb or trunk of a tree which has been naturally hallowed out by termites, cut to an average length of 1.3 meters and cleaned out with a stick or hot coals. The wood is stripped from the outside and painted with traditional Aboriginal designs. Beeswax is often used to smooth the end of the mouthpiece.

One end rests on the ground, while the player simultaneously blows and sings into the other end of the instrument, producing a deep, buzzing drone and more subtle effects: high partials, rhythmic articulations, and changes of tone color. Circular breathing, a difficult technique of taking in air through the nose while simultaneously blowing air out through the mouth, is required to play the sounds.

The didgeridoo is typically played by the Aborigines of northern Australia to accompany dance and song.
