There are a number of ways to learn the basics of conducting and ways to apply them. Rather than piecing it all together a little at a time, I offer a way to see the whole picture at once. Every part from the basic coursing orders to choosing practice touches and composing your own in your head on the spot.

Coursing Order

The grounding pattern to everything is of course the coursing order for the plain course. It is cyclical...

... 532453245324532453245324532453245 ...

How you view the order usually depends on the bell you are ringing or the bell that is unaffected in the touch (if one is). Accept viewing the order from your bell regardless of whom is affected by calls then omit your bell to have a simple working order of the remaining three.

Order Per Bell
From the Complete Order Working Order
2 2453 453
3 3245 245
4 4532 532
5 5324 324

Based on this coursing order and a few basic premises you have complete control over everything.


Effects of Calls

In Plain Bob Doubles there are two calls available, bob & single. With these calls there are only four changes you can make to the three-bell coursing order. Memorise this table and you will have a masterful control available from your head.

Transpositions
Name Effect Description Bob Single
Pop abc -> bca Pop the first one from the front. H B
Push abc -> cab Push the last one onto the front. 4 I
Front abc -> bac Swap the front pair. I 4
Back abc -> acb Swap the back pair. B H


In its simplest form, this is what you need to remember. Use whatever names suit your memory if these aren't easy for you to remember.

Call Effects
Effect Calls
Pop H / sB
Push 4 / sI
Front I / s4
Back B / sH

From that pattern you can compose any practice touch you like on-the-fly.

Premises

Unaffected Bell

Any call you make in plain bob doubles affects three of the four bells. The other one continues as if no call was made.

If you are the unaffected bell because you call a single Before (sB) or a bob at Home (H), every bell in the order moves one place to the left. Otherwise the one that is unaffected is the only one to move one place to the right.

As an example, from the random order of 432, if you wish to make continuous calls that do not affect the 3rd, you must move it through the order one call at a time, leaving the other bells where they are: 432 -> 423 -> 342 -> 432 -> ... ; this proves immediately that if you ring any length with one completely unaffected bell, the touch will consist of only three rotating coursing orders.

Special Coursing Orders

A plain course of bob doubles has 40 changes (4 leads of 10 changes each, one lead for each place-bell). When you have a particular coursing order - if no call is made - those 40 changes will be repeated forever.

5324

When the coursing order is 5324 one of those changes is rounds, at backstroke, at the lead end (of course). This means that, no matter where you enter the plain course, within 40 changes you will reach rounds and the end of your touch.

5423

The order 5423 (or 4235, remember it's cyclical) is the reverse of the plain coursing order. You will get the same changes, but they will happen on the opposite stroke to normal and in opposite order, backwards if you prefer. One of the 40 changes in this order must of course be rounds; but it will happen at handstroke not backstroke as usual.


Composing Touches

Based on these premises, when choosing a touch of plain bob doubles you can quickly generate the touch in your head knowing exactly where you will make the calls based on which call at which position has which effect on the order.

Choice such as wanting to call a bell unaffected - while ringing a different bell - are elementary to implement.

This is best demonstrated by example. Let's assume you are going to ring the 3rd, but you have a learner on the 2nd that you wish not to be affected throughout a touch.

  • You are ringing the 3rd: the coursing order starts at (and omits) 3: 3245
  • You are calling the 2 unaffected: all calls will move the 2 one place to the right.

Immediately you know all the coursing orders in the touch:

245 -> 425 -> 452 -> 245

You can then choose for each change in the coursing order when you wish to make a call that will make the change you need.

  • 245 -> 425
    • Front Two Bells Swap
    • Calls Availab


2nd Unaffected from the 3rd
Name Effect Description Bob Single
Pop abc -> bca Pop the first one from the front. H B
Push abc -> cab Push the last one onto the front. 4 I
Front abc -> bac Swap the front pair. I 4
Back abc -> acb Swap the back pair. B H


3245 3425 Front (I / s4) 3452 Back (B / sH) 3245 Push (4 / sI)

Which means the standard 120 from the 3rd with the 2 unaffected is , IB4 (In, Out, Make), or you can play with it by swapping in singles as you please. Any of the following will still come round and still leave the 2 unaffected, as called from the 3rd:

IB4 - True 120 IBsI - True 80 IsH4 - True 80 IsHsI- True 80 s4B4 - False 120 s4BsI - True 80 s4sH4 - False 120 s4sHsI - True 120
