(countable); (onomatopoeic), (music) A didgeridoo is a long and straight, wooden wind instrument that AustralianAborigines traditionally use. Roughly the size of a man, it produces sound when you continuously blow into it.
Didgeridoos often have drawings showing mythological elements of the Aboriginal culture or clanic symbols.
While playing didgeridoo, you can imitate some natural sounds such as bird songs.
