Groote Eylandt yiraka (didgeridoo) playing style

This is an impromptu recording of yiraka playing, demonstrated by Jason Guwarnbal first and taken up later by Djalu' Gurruwiwi. Yiraka is the name for the didgeridoo in Groote Eylandt among the Anindilyakwa-speaking people. The song played by Guwarnbal is fishing for parrotfish (ra:kum ga larlu). When Djalu picks up where Guwarnbal left off, Guwarnbal commences singing, momentarily, in a shaky-voice manner characteristic of Anindilyakwa singing. At the end, Djalu' demonstrates the yiraka mouth sound patterns for the song he had just played.
