Method ringing (original) (raw)

Method ringing (also known as scientific ringing) is a form of change ringing in which the ringers commit to memory the rules for generating each change of sequence, and pairs of bells are affected. This creates a form of bell music which is continually changing, but which cannot be discerned as a conventional melody. It is a way of sounding continually changing mathematical permutations. It is distinct from call changes, where the ringers are instructed how to generate each new change by calls from a conductor, and normally only two adjacent bells swap their position at each change.
