What is the history of African rain sticks and how have they been used traditionally?

African rain sticks have a long history in various African cultures, where they were traditionally used in rituals and ceremonies to invoke rain for agricultural purposes. These instruments are typically made from hollowed-out branches or tubes filled with small stones or seeds that create a soothing sound when tilted. The sound of the rain stick is believed to mimic the sound of rain falling, and it is thought to have a calming and meditative effect on those who listen to it. Today, African rain sticks are still used in traditional ceremonies and celebrations, as well as in music and dance performances.
