A mythology has grown up around the didjeridu which among other things centers on the seemingly paradoxical relationship between the instrument's simplicity of means and yet complexity of sound possibilities, its associations with an essentialist spirituality and naturalness, and its symbolic potential.

Made from various types of eucalptytus trees the didjeridu is simply a hollow tube. The instruments played at Yirrkala today are generally 1.3 to 1.5 meters long and made from the narrow trunks of stringy bark eucalyptus (eucalyptus tetradonta). The instrument maker seeks out a tree whose cambrium has been eaten out by termites. After the tree is felled and cut to a proper length the bark and outer layer of wood are peeled and cut away. Some smoothing out of the inner surface of the blowing end and optional decorative painting completes the construction of an instrument.

Different sets of playing techniques are found in various Aboriginal cultures who use the didjeridu within Australia, but one universal technique is the production of a constant drone through the use of circular breathing. While blowing, the player retains small amounts of air in the cheeks; this air is then used to sustain the drone when taking quick breaths in through the nose. The basic blowing technique involves buzzing the lips in a way that is fairly analogous to Western brass instrument technique. One major difference is that the embouchure (the position and application of the lips on the mouthpiece of a wind instrument) of a didjeridu, while well-controlled, is less taut than the Western brass embouchure. The resulting greater flapping of the lips helps give the didjeridu its characteristic rich sound.
