Didgeridoo (or didgeridù) is an onomatopoeic origin word, used by occidental peoples, that refers to the antique wind instrument of Australian aborigines. In Australia this instrument is indicated with at least fifty different names, according to the various peoples living in the Country: therefore one can run through djalupu, djubini, ganbag, gamalag, maluk, and up to yirago, yiraki, yidaky... Didgeridoo originated from North Australian aborigines. There are no reliable sources stating its exact age, but it could possibly go back to at least fifteenthousand years ago. Didgeridoo is classified as a "labial reed airphone" musical instrument, it has a light conical hose shape of variable lenght (about a meter or a meter and a half, but can also reach two meters and a half). This instrument is made out of an eucalyptus branch ( a plant widely diffused in the North of Australia); the branch is chosen among those whose inner part has been hollowed by termites. Firstly peeled, cleaned and accurately finished, the instrument is then decorated with traditional paintings which remind of aborigines mythology. In aborigines tradition the didgeridoo is played exclusively by men, which use it not only as a wind instrument where they can blow and meanwhile utter words, sounds, noises, but also as a percussion instrument if hit with sticks or boomerang.
