Calling Bob Minor, further thoughts

Anoth­er aspect of call­ing a long touch – let alone a quarter peal – is remem­ber­ing where you’ve got to, and what hap­pens next.

The only long touches I’ve pre­vi­ously called have been quarter peals of bob doubles, where the prob­lem is keep­ing track of call­ing exactly 10 120s, and not los­ing track of how many you have rung so far. For that meth­od I’ve adop­ted the tech­nique of asso­ci­at­ing each suc­cess­ive 120 with a par­tic­u­lar bell, so that you call a 120 asso­ci­ated with the 2, then a 120 asso­ci­ated with the 3, then the 4, then the 5; then anoth­er 120 asso­ci­ated with the 2, then the 3, 4 and 5 in turn; and then yet anoth­er 120 asso­ci­ated with the 2, then the 3 – and then you’ve rung 10 120s.

The advant­age of this aide mem­oire is that while ringing you just have to remem­ber which bell is asso­ci­ated with that 120, and at the end of the 120 you move on to the next bell. And you have to remem­ber wheth­er this is the first sweep, the second, or the last (half-)sweep, but that is very con­sid­er­ably easi­er to do, partly because count­ing to 2 is an awful lot easi­er than count­ing to 10, and also because a look at the clock will give you a pretty clear indic­a­tion of which sweep you’re in. Two fur­ther points about Bob Doubles. First, it is very easy to asso­ci­ate a par­tic­u­lar bell with each 120, because in any 120 a par­tic­u­lar bell will be the obser­va­tion bell, unaf­fected by the calls, and the con­duct­or is focus­sing on that bell and call­ing bobs when it is about to ring 4 blows in 5th place. So it is easy and nat­ur­al to asso­ci­ate a bell with a 120 and to remem­ber which bell it is at any moment. The second point is a foot­note to any­one read­ing this who might be set­ting out to ring a quarter of Bob Doubles: don’t for­get that 10 120s is only 1200 changes and you need to add anoth­er 60 to get to the quarter peal.

So how is this applic­able to quar­ters of Bob Minor, and par­tic­u­larly to the com­pos­i­tion dis­cussed? One idea is to use a sim­il­ar count­ing scheme to keep track of the courses of the com­pos­i­tion. In a 1260 of Bob Minor there are 105 leads of 12 blows each, or 21 courses of 60 blows each. Each course is 5 leads in length and at the end of each the ten­or – which is entirely unaf­fected by all the calls of Bob and Single – returns to its ‘home’ pos­i­tion of dodging 5–6 down. Unfor­tu­nately, and unlike the Bob Doubles count­ing scheme, there is no obvi­ous and easy nat­ur­al asso­ci­ation of a course with a dif­fer­ent bell.

What we have instead is a 720 of 12 courses fol­lowed by a 540 of 9 courses. If we alloc­ate all 6 bells to a course then that is twice through the bells for the 720, and one and a half sweeps through for the 540:

1: bob (wrong), plain, plain, plain, bob (home)
2: bob (wrong), plain, plain, plain, plain
3: bob (wrong), plain, plain, plain, bob (home)
4: bob (wrong), plain, plain, plain, plain
5: bob (wrong), plain, plain, plain, bob (home)
6: bob (wrong), plain, plain, plain, single (home)

1: bob (wrong), plain, plain, plain, bob (home)
2: bob (wrong), plain, plain, plain, plain
3: bob (wrong), plain, plain, plain, bob (home)
4: bob (wrong), plain, plain, plain, plain
5: bob (wrong), plain, plain, plain, bob (home)
6: bob (wrong), plain, plain, plain, single (home) which com­pletes the 720

1: bob (wrong), plain, plain, plain, bob (home)
2: bob (wrong), plain, plain, plain, single (home)
3: plain, plain, plain, plain, single (home)

4: bob (wrong), plain, plain, plain, bob (home)
5: bob (wrong), plain, plain, plain, single (home)
6: plain, plain, plain, plain, single (home)

1: bob (wrong), plain, plain, plain, bob (home)
2: bob (wrong), plain, plain, plain, single (home)
3: plain, plain, plain, plain, single (home) which com­pletes the 540

Does this help at all? I’m going to think about that!
