Didgeridoos & Clapsticks "Pridaki" or "Yidaki" is one of several Australian Aboriginal names for the instrument known as the didgeridoo. This fascinating wind instrument is made from a tree branch that has been naturally hollowed by termites. It is played using a technique known as circular breathing (expelling air from the cheeks while breathing in through the nose) which enables a continuous drone to be maintained. "Boorn Yoora" or "Clapsticks" Boorns-stick and Yoora-clapping to keep time with the music. The specialy selected, very dense and resiliant brown mallet timber (Eucalyptus Astringens) imparts the distinctive "ring" to these traditional sound sticks. These ancient musical instuments are amongst the earliest known to human kind. Clapsticks have been traditionally used in corroboree (dance) for thousands of years as an accompaniment to the didgeridoo and song. Only the combination of special hard wood and the characteristic and shape tapered at each end, can produce the unique pitch and volume to carry the rhythm of the music or punctuate the story of the dance.
