A "rattle" is a musical instrument often made of wood, plastic, or metal that produces sound when shaken. It typically contains small objects, like beads or seeds, that create noise as they move inside the container. Rattles are commonly used in children's toys and in various cultural music traditions. In addition to being a toy, rattles have historical significance in many cultures. They are often used in rituals and celebrations, symbolizing joy and festivity. Some traditional rattles, like those used by Native American tribes, are crafted with intricate designs and serve both musical and spiritual purposes.
