This evening I rang a quarter of Grandsire Triples in Ringing Room - very satisfying, almost no trips, hardly any internet delays, good pace and rhythm for a time of 36 minutes.

Alban Forster called this composition:

6 part, calling - for s*
in parts 3 and 6.
For handbells: 3-4 coursing throughout.

I hadn't particularly thought about keeping 3-4 (which is the coursing pair in Grandsire) coursing throughout a quarter, but why not? Of course they are not literally coursing in every lead, because there is a split lead when the treble and the hunt bell course in between them, just like on the tenors in Plain Bob. But they stay in the coursing position throughout, even when the 3rd is in the hunt.

Like many compositions of Grandsire, we have to take care reading it, because the courses are not all the same length and this isn't obvious from the tabular layout. The first two courses are four leads each, and the third course is seven leads.

It's easy to remember the calling from 3-4. There are three bobs with 3-4 dodging together in 6-7 (those are the bobs at 1), then the bob at 3 puts the 3rd into the hunt, it comes out a lead later at 4 with a single (or a bob in parts 3 and 6), and then the single at 6 has the 3rd dodging 4-5 up so that one more plain lead gets it back to making 3rds for the part end.

Calling from the trebles would be another easy option because the 2nd is also fixed at the part ends. Alban called from the tenors though, which requires a bit more watching of the other bells.
