Whistle
A plain, tapering tube topped by a bulbous open end and an appendage with a single finger hole is a common southern Congolese whistle form. This rare instrument, an elaboration of the simpler form, is incised with line-filled triangles, and decorated with coiled copper wire and an imposing fluted lance carved at its lower end. Among the Kuba people nshyemb may also indicate an ivory flute.
