The quartz crystal didgeridoo is a wind instrument, one of the oldest in the world, and is a simple instrument, essentially a hollow quartz crystal tube that is played by vibrating the lips and breathing in harmony with the sound. The wooden didgeridoo originated 1000 years ago in the Aboriginal tribes of Australia, and was used in ceremonies where, according to local custom, by playing the instrument, the living were able to converse with the spirits of the dead, and it was also used as a tool for communicating with nature.

The process of making this instrument by the indigenous tribes is very interesting, the aborigines took advantage of the termites' habit of gnawing on the wood and inserted the trunk of a cut eucalyptus tree into a termite burrow, the core of the wood became food for the termites and the hollowed out trunk left behind became a musical instrument for the aboriginal people. The didgeridoo has become a crystallization of Aboriginal wisdom, culture and art, and in a sense has become a symbol of Australia.

The modern didgeridoo design is a departure from the traditional Australian Aboriginal didgeridoo, which was redesigned and innovated by musicologists in the late 20th century, using non-traditional materials and shapes. People began experimenting with different materials to make didgeridoos, such as quartz crystals, fiberglass, clay, resin, metal, PVC pipes, and carbon fiber, to name a few. The resulting didgeridoo is usually cylindrical or conical in shape and 1 to 3 m (3 to 10 ft) in length. Most are about 1.2 m (4 ft) long. In general, the longer the instrument, the higher or lower its pitch. A flared instrument can be played at a higher pitch than a non-flared instrument of the same length. However, this practice has generated a great deal of debate among indigenous practitioners and non-indigenous peoples about its aesthetic, ethical and legal issues.
