[r-t] Maypole / big singles / ASCY dinner touch

[Philip Earis]

It's good to see Alan Reading called a very neat, well-arranged composition of Maypole yesterday (http://www.campanophile.com/view.aspx?113738):

=====
5280 Maypole Alliance Maximus
Arr. A G Reading
               234567890ET
s10.s11        7890ET23456 (12 leads)

s=1890ET
11 Part
=====

The composition has a full course of each cyclic course.  The linkage between courses is very nice here, using the big singles "trick" that was described on this list in October 2005 (http://www.bellringers.net/pipermail/ringing-theory_bellringers.net/2005-October/001123.html)

I used the same idea in a December 2009 composition of spliced maximus we rang (http://www.campanophile.com/view.aspx?93417).  Here, the base is the classic Pipe cyclic 6-spliced.  Ariel is replaced by a double method Ashendon - this has regular half-leads, meaning you can insert a big single at both halflead and at the leadend immediately following, to jump to a different cyclic part straight away:

I'm sure there are further interesting applications of the same trick.

On a related point, using a single affecting half of the bells was also something I used in the November 2010 ASCY handbell dinner touch, which was on 16 bells (http://www.youtube.com/watch?v=BGIaqTyMtVc)

We started by using the lovely mirror-symmetric transition +70-5T-3B- which takes you directly to the row tittums, exploding out from the middle of the change like the best call-change sequences. To get from tittums to the "mega-tittums" coursing order we need to swap pairs 9-D, 0-C, E-B, T-A.  Beautifully, using a bit of structure we can do this in a single change with a big (12345678) single when these pairs come together after a bit of plain hunt. A bit more plain hunt, a lead of Bristol, and then a "Bastow redux" link brings it back round.

Incidentally, the mirror-symmetric blocks can of course be reduced to maximus, ie +58-30-1T, getting to the row tittums in 5 changes.  10 repetitions of this block brings up a beautifully concentrated fluid 50-change touch including queens, reverse rounds, reverse tittums, reverse queens and other pleasant goodies.
