The yidaki is a ceremonial Indigenous Australian instrument traditionally made from a eucalyptus tree hollowed by termites. As is the tradition of the Yolngu, only men are allowed to play this instrument. It is unfortunately misunderstood by Europeans, who falsely named it didgeridoo.
Players of the yidaki use a technique called circular breathing, which is essentially when you continuously breathe out while sporadically breathing in. The yidaki produces a deep drone that accompanies ceremonial songs, alongside clapsticks. Other drone instruments include bagpipes (one pipe), aulos, and tanpura.
