Grandsire

Grandsire is one of the standard change ringing methods, which are methods of ringing church bells or handbells using a series of mathematical permutations rather than using a melody. The grandsire method is usually rung on an odd number of bells: Grandsire doubles is rung on five working bells, grandsire triples on seven, grandsire caters on nine and grandsire cinques on eleven. Like all odd-bell methods, where there are sufficient bells, it is normally rung with a "cover" bell, which stays in the last position in each row to add musicality.
