Many cultures in Africa, the South Pacific and South America have used the seed-pods of various plants, known as gourds, to make rattles and other percussion instruments.

Generally, the seed pods are dried and then filled with beans, beads, or small stones.

In South America, there is a tradition of playing rattles of this type in pairs. They are known as maracas
