Some believe that the didgeridoo is the world's oldest wind instrument. It may date back to 20,000 BC. The Didgeridoo is part of the musical, healing and ceremonial heritage of the aboriginal peoples of Australia. Traditional playing of the didgeridoo is accompanied by tapping out soft rhythms on the sides of the instrument while it is being played. To play the didgeridoo, you blow into the mouthpiece while creating a buzzing with your lips. Circular breathing allows you to continually blow air from your mouth without ever stopping for breath. This technique allows you to blow an uninterrupted drone since you are inhaling and exhaling at the same time. It takes some practice!
