Australian Aboriginal music includes the music of Aboriginal Australians and social, cultural and ceremonial observances of these people, down through the millennia of their individual and collective histories to the present day, and has existed for 40,000 years. The traditional forms include many aspects of performance and musical instrumentation which are unique to particular regions or Indigenous Australian groups. A didgeridoo is a type of musical instrument that, according to western musicological classification, falls into the category of aerophone. It is one of the oldest instruments to date. It consists of a long tube, without finger holes, through which the player blows. It is sometimes fitted with a mouthpiece of beeswax. Didgeridoos are traditionally made of eucalyptus, but contemporary materials such as PVC piping are used. In traditional situations it is played only by men, usually as an accompaniment to ceremonial or recreational singing, or, much more rarely, as a solo instrument. Although traditionally the instrument was not widespread around the country - it was only used by Aboriginal groups in the most northerly areas - today it is commonly considered the national instrument of the Australian Aborigines and is world-renowned as a unique and iconic instrument.
