The Didjeridu is a simple trumpet whose long tube is formed from a eucalyptus branch hollowed out by termites. It is played by male aborigines of Northern Australia to accompany singing and dancing. A complex playing technique is required which demands precise control and coordination of lips, cheeks, tongue, voice, and lungs. Didjeridu players use a skill called circular breathing which allows them to play continuous melodies.
