The didgeridoo ( also spelt didjeridu, among other variants) is a wind instrument, played with continuously vibrating lips to produce a continuous drone while using a special breathing technique called circular breathing. The didgeridoo was developed by Aboriginal peoples of northern Australia at least 1,500 years ago, and is now in use around the world, though still most strongly associated with Indigenous Australian music. The Yolŋu name for the instrument is the yiḏaki, or more recently by some, mandapul; in the Bininj Kunwok language of West Arnhem Land it is known as mako.
A didgeridoo is usually cylindrical or conical, and can measure anywhere from 1 to 3 m (3 to 10 ft) long. Most are around 1.2 m (4 ft) long. Generally, the longer the instrument, the lower its pitch or key. However, flared instruments play a higher pitch than unflared instruments of the same length.
Didgephone is a new form of Didgeridoo made by Kaveh Mirali, the maker and musician of local and ritual instruments in January 2018 in Iran, Alborz province. In order to protect the rights of animals, this instruments, which was usually made with the body of an African Kudo deer, was made of composite by him.
