The “Didgeridoo”… can you tell me what it is?
The Didgeridoo (or Yidaki) is the traditional wind instrument of some North Australian Aborigine tribes, who have played it for at least 5000 years in their ceremonies. The inside of a trunk- or branch from the Eucalyptus tree is hollowed out by termites.
The acoustical and rhythmical variety occur due to the combinations of mouth movements, breathing techniques and vocal effects based on a key tone which slightly varied in the tone pitch and overblown tones. Playing the Didgeridoo requires a “Circular Breathing” technique which allows a constant tone to be produced and held.
