A wind chime has several objects which produce a "chime" when they strike each other. When a wind chime is left hanging freely, the wind makes the objects move and they strike each other to produce a chiming sound.
At the heart of a chime is a piece of metal of exact dimensions. All objects have a natural frequency at which they will vibrate when given a certain amount of kinetic energy. If this natural frequency is a the same frequency of a audible sound, then that is what you will hear.
Wind chimes can be made of various materials, including METAL,glass , shells wood. Most are made from metal tubes that are arranged in a circle with an object in the centre that can strike the tubes. Metal tubes are cut to various lengths which alters the sound they make when they are struck. The larger the tube, the deeper the sound. The tubes can be constructed in differing diameters too, which also changes their sound. Tubes with smaller diameters create a higher pitch than those with large diameters.
Regardless of the size of the tubes, they work on the same principle vibration. When a tube is struck, it vibrates the tube. Unlike an instrument, the sound is independent of vibrations of the air within the tube

Large bells are out of fashion in schools today, but the electric version (sounding more like buzzers to be true) replaced them in most schools to signal the end of classes or recess.
