This ability to control the speed of bells soon led to the development of change ringing where the striking sequence of the bells is changed to give variety and musicality to the sound.

They find use in many areas as a percussion instrument, including the classic sleigh bell sound and morris dancing. They are typically used as a cheaper alternative to small 'classic' bells.
