Goura (instrument)
The goura is a single stringed instrument, blown rather than plucked or strummed, with the string attached to a coconut shell resonator and with a tension noose wrapped around the string to adjust the pitch. It is considered the national instrument of the Khoikhoi people of South Africa.
