# Coursing Order

Lots of ringers talk about coursing order, but even some of the old hands who nod along don't know what it is or why its useful. This is where you can tell the difference between people that call a touch, quarter or peal, and those who conduct.

The basic Plain Bob coursing order is (for minor) 53246, quite simply put this is the order in which each bell passes the others and the treble barges in there at some point. e.g. the 2nd passes the bells in the order 4653146531 as it comes off the lead (it of course can't pass itself). Seeing this is the first step.

At this point it is worth mentioning that callings are normally based around the tenor, so the 6th in this instance.

Once you are happy with this you need to learn what happens when you call a bob or single, you may have noticed that a bob at Home only affects the 2, 3 & 4 so it stands to reason that these are the only bells to change in the coursing order. The way it changes is like this;

``` 5abc6 becomes 5bca6
53246 becomes 52436
```
``` this rotates the middle three bells in the couring order
```

So now lets say you are ringing the 6th to a touch of Plain Bob Minor, the coursing order up till the first call is, 53246, you call a bob at home, the coursing order then becomes 52436 and remains this way unitl the next call, lets say you call a second home, the coursing order becomes 54326 until the next call, the third home will bring the coursing order back to 53246 and the touch comes round.

Now that wasn't too hard was it. The next call you are likely to be using is a Wrong, if you think about the bells that are affected at a wrong (being the first call) you will see that it will be the 2, 3 & 5. These are rotated in the couring order in the same way;

``` abc46 becomes bca46
53246 becomes 32546
```
``` this rotates the front three bells in the couring order
```

You can now attempt to call the touch, three wrongs, the coursing order changes thus;

```  53246
W 32546
W 25345
W 53246
```

Now we come to the realy icky part, we have seen how just using calls at Wrong and Home the same bells are affected all the time, however we can now use both. Below is a standard 360 of Plain Bob Minor, the first half of a 720, written out with the coursing orders next to the calls that produce them.

```  53246
W 32546
H 35426
W 54326
W 43526
H 45236
W 52436
W 24536
H 25346
