Research in music archaeology in southern Africa has just begun. Available evidence dates back from around 10,000 years ago, from the Later Stone Age up to the Iron Age. The artefacts fall into two groups, namely aerophones, where sound is produced by vibrating air, and idiophones, where sound is produced by solid material vibrating. These artefacts include spinning disks, bullroarers, bone tubes that could have been used as flutes or whistles, clay whistles, keys from thumb pianos (also called lamellophones or mbiras), musical bells and an ivory trumpet. The list is not exhaustive and more research needs to be conducted. These music-related or sound-producing artefacts are made from various materials, including bone, ivory, metal and clay. The artefacts show how integral sound and music production was in the socio-cultural practices of people in the past, most likely for entertainment and rituals. Sound production and music making is a sign of being fully human.
