April Day is a variation, rather than a method, as it takes one method, in this case Plain Bob Doubles, but uses a different call from normal. Here the call is a Grandsire Single. At normal calls in Plain Bob, the difference from the method only lasts one blow, then you get on with ringing Plain Bob again. In variations, a whole chunk can be changed. Depending on how you learned to do a Single in Grandsire, applying this in the context of Plain Bob may be harder or easier.
If you look at the structure of a Single in Grandsire Doubles, you can see the all the work fills the space above the treble, which is shown in red. One bell is making 2nds over the treble, while another does four blows in 3rds place above that. The two bells at the back double-dodge together; one lying behind then dodging down and the other dodging up, then lying behind.
So, the key to ringing this is knowing where you pass the treble. If you pass the treble in 1-2, make seconds (this is the bell which is unaffected). If you pass the treble in 2-3, make long 3rds and go back in. The other two bells double-dodge at the back; if you're already there when the call is made, double-dodge down, but if it's called when you're not yet at the back, double-dodge up.
And then what to do next time?
Well, the answer is again to watch for the treble. You do know where you pass the treble in Plain Bob Doubles, don't you??
|Pass the treble||Next piece of work|
|2-3||Dodge 3-4 up|
|3-4||Four blows behind|
|4-5||Dodge 3-4 down|
If you want the traditional table of what to do at a call, it is given below. But it is worth learning where you pass the treble too...
|You were going to do||Do this instead||What to do next time|
|Make 2nds||Make 2nds (unaffected)||Dodge 3-4 down|
|Dodge 3-4 down||Double-dodge 4-5 down||Dodge 3-4 up|
|Four blows behind||Double-dodge 4-5 up||Make 2nds|
|Dodge 3-4 up||Do Long 3rds||Four blows behind|
To call a 120, call any bell (except the 2nd) unaffected at each of three calls. Note that, like in Grandsire, the call has to made at the handstroke when the treble is in 3rds place on its way down. If you are calling yourself unaffected, this is your first blow in lead.
