A bell rotates through almost a full circle, mouth-up at the start of each stroke and mouth-up at the end. The ringer is not pulling a rope to make a clapper hit the bell; the clapper is inside, and the bell itself is what swings. Between strokes the bell rests balanced over its bearings, mouth pointed at the ceiling, the stay — a wooden batten — propping it against the slider so it won't fall back. The ringer holds the rope. The bell holds the silence.
Then the call comes from the conductor — go, Bob — and on the first stroke the eight bells sound one after another from treble to tenor. A round. The bells fall in a descending major scale, or close to one, depending on the foundry. The interval between each strike is the same: about a quarter of a second. After enough rounds the conductor calls bob and the order of the bells changes. Two bells swap. Then on the next change another two swap. The numbers on the page rearrange themselves, shifting by one position at a time, never repeating until every possible ordering has been rung.
There are 40,320 orderings of eight bells. A peal of all of them takes about three hours.
The mathematics is older than the notation for it. By the seventeenth century the ringers in English towers had worked out the principles for moving from one order to the next without anyone having to think during the work. A bell already swung; it could not be hurried or held without disturbing the line. So the changes had to be ones that any bell could make from where it was: hold its place, or move one position forward, or move one position back. From these small motions, organised by patterns called methods — Plain Bob, Grandsire, Stedman, Cambridge, Yorkshire — the band rings its way through the permutations without a list in front of them. Each ringer has a part to play, a place in the order at every change, but they don't recite their place; they hear when their bell should sound and they pull it. The pattern lives in the rope-pull and in the ear.
A learner first rings rounds. Plain rounds, the descending scale, can be done within a few weeks. Then call changes — the conductor names the swap, three to four, two to five — and the band moves the named bells. After call changes, the learner takes a single bell through a method while the rest of the band holds steady around them. Plain Hunt on five is the first real method: the learner's bell moves up to the back, then down to the front, in a regular zig-zag through the line. It takes months to ring it cleanly. The bells are unforgiving. A bell that strikes a fraction late lands in another bell's quarter-second and the listener hears it. The listener at the bottom of the tower, cup of tea, judging.
A bell is not a percussion instrument exactly; it's a long-decaying chord. The fundamental, the hum, is an octave below the strike note. There are partials above and below it, named by foundrymen — the prime, the tierce, the quint, the nominal — and these partials are why two bells in the same key can sit poorly together. They are also why a tower's tenor — the heaviest bell, often a ton or more — has a sound that lasts long after its rope is gone. You can stand in a churchyard after the ringing has ended and the tenor's hum will still be in the stone of the wall.
Rope-sight is what the band calls the thing they teach by. You watch the ropes of the other ringers, not their faces. The rope of the bell behind you in the order rises just before yours; you take that as the cue and pull. If you watch faces or count in your head, you fall behind. If you watch the rope, you fall in. New ringers describe the moment rope-sight arrives like a click: I stopped counting and I was just there. Old ringers say nothing about it because they no longer remember not having it.
A peal — the full 40,320 — is rare. Most ringing is shorter: a quarter peal of about 1,260 changes, run on Sunday morning before the service, takes about forty-five minutes. The band stands in a circle. They don't speak between calls. The conductor is one of them, ringing a bell like the rest, but holding the method in his head and calling the bobs and singles when the structure asks for them. The other ringers obey without acknowledging the call; they just do the thing the call requires. A good band sounds like a single instrument played by one person with eight hands.
When the peal ends the bells are rung back to rounds, then stood — each ringer slowing the swing until the bell rests mouth-up again, balanced on its bearings, the stay against the slider. The ropes hang in the chamber. Outside, the village hears the last note die into the wall.
