[r-t] New major frameworks - Tom Perrins

Thanks guys for your remarks. Just one thing, re Graham:

Depending on what you're defining as 'exact' 6 parts, this may not appear in exhaustive searches. Of course, adding a single halfway and end is a trival variation on the standard part, but it's still a variation of sorts. (I.e. all 6 parts I've encountered appear to have 65 swapping with 234 to produce a 'perfect' 6 parts). None-the-less this just came across as a nice alternative to the 42365 etc part end comps of which there are plenty to choose from.

Tom.

I mentioned his 10-part major earlier this year (http://www.bellringers.net/pipermail/ringing-theory_bellringers.net/2011-January/003720.html), but he's recently produced a couple of interesting new approaches.

> Motivated by a desire for a simple handbell framework for spliced coupled with little-bell music, Tom has come up with a nice simple 8-part format for the Pitman's 4 methods:

> 5120 Spliced S Major (4m)
> Thomas M Perrins
> 23456 M W H
> 54632 s - s  CSS.C.L.
> 34625 s s    L.BBBBBB.L
> 25643 s -[s] CSC.S.SSC
> 8 part, calling [s] in 4 and 8 only,
> 3-4 & 5-6 course for all the Bristol and all but 4 leads of the London.

> The structure is very suited to handbells, with adjacent pairs being preserved, and yet strangely little-utilized so far: most existing tenors-together "handbell-motivated" compositions have either been 1-parts or multi-parts tending to keep one pair fixed at the part-ends, such as 3 parts rotating 234. A quick search shows Don Morrison has a couple of compositions using the same concept to Tom, but there are surely further possibilities here.
