kokalu; langumumuhbu

Source term: boy's bullroarer

langumumuhbu (Tongan): built on lango, "house-fly", and mumu, "to hum"; McLean spells it langumumubu. kokalu: the other Tongan name, unglossed.

Tongan boys bent a doubled coconut frond open on a bow cut from a leaf midrib, tied on a second midrib for a cord, and whirled it fast until it hummed. They called it kokalu, or langumumuhbu. The second name is built on lango, the Tongan house-fly, and on the same humming mumu that Samoan children put into their lago mumu. Tongan and Samoan sit on the two main branches of the Polynesian family, so a toy name the two share may be nearly as old as Polynesian itself. The only description of it comes from W. C. McKern, who worked in Tonga for the Bishop Museum in 1920–21.

A doubled frond from a coconut leaf was held distended by a bow, made from the midrib of a coconut leaf frond … which could then be whirled rapidly to produce a humming noise.

W. C. McKern, manuscript p. 669, quoted in Richard M. Moyle, Tongan Music (1987), "Free aerophones".
