Herbert Basedow called it a “bamboo trumpet”, “drone-pipe” or “didjeridoo.” Sir Baldwin Spencer in his analysis of recordings of the Australian Aboriginal singing suggested the more specific term “conch,” drawing a comparison to shell trumpets despite it being made of wood or bamboo, noting it was “commonly called a trumpet by the whites, but really a kind of conch, made out of a hollow bough.”
Spencer, in his analysis of recordings, referred to the work of Roth, who documented the term “yiki-yiki” for a long wooden trumpet used in areas of the Cape York Peninsula. In his own documentation of Native Tribes of the Northern Territory of Australia, Spencer also listed the sacred names “jiboulu” for the everyday trumpet and its ritual counterpart, “Purakakka.”
From Central Australia, Spencer and Gillen described the “ilpirra” (or “ulpirra”), a shorter, rudimentary tube used in love-magic ceremonies, which they distinguished as a “rudimentary trumpet” that was sung through to intensify the voice rather than played with vibrating lips.
