This instrument is a war horn made of bamboo. The end of the bamboo cane is cut off
and, on the side, a woro (large hole) is made to act as a mouthpiece.
The instrument is not usually played outside of its war functions for fear of
recalling war and other misfortunes. Wana people believe that the sound of something can
recall whatever it signifies, so the act of playing war music outside of war times can bring
about war.
