Traditional Aboriginal musical instruments, Didgeridoos are long wooden flutes. Didgeridoos are considered one of the oldest musical instruments in the world, and were originally made from bamboo. Modern didgeridoos, however, are made from hallowed out limbs and tree trunks. The average instrument is approximately three and a half feet in length, and was originally played by Aborigines to accompany chants and songs. Didgeridoos are played by blowing air through the tube, which produces low, droning noises that are varied to create complex rhythmic patterns.
