Narrative: Bells are a percussion instrument and an idiophone which means their sound is created through their vibrations. Bells are cast using a process called bellmaking or bellfounding. They are made to exact formulas so given the diameter one can calculate every dimension of the bell as well as its musical tone. The frequency of the bell’s note varies with the square of the thickness and inversely with the diameter.
