Though it was particular to the clans in northern Australia originally, the didgeridoo (or yidaki) is now the most recognizable instrument in Aboriginal music. The classic didgeridoo is made from a termite-hollowed bamboo or eucalyptus limb, though today it's common to find didgeridoos made of PVC. The didgeridoo is played as a kind of woodwind aerophone, producing a low frequency sound that can be sustained and heard over long distances.
