"The didjeridu of the Australian aboriginal people is an ancient and deceptively simple instrument, consisting of a length cut from a narrow tree trunk or branch and hollowed by the successive action of fire and termites. Skilled players, however, are able to produce a wide repertoire of interesting musical effects including a rhythmic drone, striking timbre changes, and sounds that are voiced as well as played." Acoustics Australia, Vol 24, pp 11-15 (1996).
