What is "lokole"

The lokole is a traditional slit drum played by the Mongo people in different areas of the Congo region, e.g., in the Kasai area. It is used both as a musical instrument and as a log drum to send messages in the bush; for example, it is known to be played to announce someone's death to the neighboring villages. It is a deep-sounding slit drum, traditionally made out of a hollow tree trunk. It is beaten with sticks, and can produce a small range of bass notes.
