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.
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.
53246 becomes 52436
