Yidaki is the aboriginal name for the Australian didgeridoo. It is traditionally made from eucalyptus wood that has been hollowed out by termites. In this virtuosic piece for the interesting solo choice of baritone saxophone, various techniques are employed to emulate the didgeridoo, including quarter tones, multiphonics, growls, singing, and harmonic sweeps.
Suggestions are included for the fingering of multiphonics.
