Further to the correspondence on this subject a while ago, Terry Streeter (who is not on this list)
has given me permission to repost his latest Differential Royal creation, which may be of
interest. The notation for the first half lead is as follows:
hl 70, lh 14
... and since this results in a 3-cycle (bells 1-3) and a 7-cycle (bells 4-10) with 1, 2 and 3 occupying
each of the 10!/(7!*3!) = 120 positions in each half lead, the plain course is a true 240x3x7 =
The line is very dynamic, with frequent changes of direction. The only side effect of this is
that bells sometimes get stuck on the back for reasonable periods to accommodate other bells
performing points/fishtails. However, this does at least provide a well earned breather.
Best of all, this has been optimised musically, in contrast to previous attempts (mine included). Not
only do the back 7 only meet at the front and back in coursing order, the 4 bells at the front/back of the
change when 1-2-3 are absent meet as a coursing quadruplet, therefore maximising 4 bell rollups in
what is a limited framework for music. This feature should also aid conducting/correction.
Now to attempt to ring it. How hard can it be?
