Bells are musical instruments that produce sound when struck. They are often made of metal and come in various sizes, from small hand bells to large church bells. When a bell rings, it creates a clear, resonant tone that can be heard from a distance. Bells are commonly used in places like schools, churches, and even in some homes to signal the time or call people together. In addition to their practical uses, bells have cultural significance in many societies. For example, in Buddhism, bells are used during meditation to help focus the mind. Similarly, in Christmas traditions, bells symbolize joy and celebration, often heard in festive music and decorations.
