I'm pleased you liked it. I think perhaps you have provided the answer
to why many compositions of atw spliced have random methods. It's
because the methods have been fitted in to a composition, rather than
the composition being fitted to the methods. If you look at Norman
Smith's or Chandler's 23, it is obvious that the methods were fitted in
to a predefined, and consequently neat, composition. I could be wrong,
but I assume that Chandler simply took Norman Smith's composition and
substituted harder methods. It also appears that he gave up trying to
find a substitute for Pudsey.

I doubt my "toolkit" is as impressive as many other subscribers to this
list. I basically just have a fairly general search program that does
an exhastive search of a 'map' (if that's the right term). The map is
generated using the list of methods, the list of part heads, and a list
of list of allowable course or lead heads. Also, the search program can
be given a composition to start with which it will then attempt to
extend by finding somewhere to insert a new block. In fact, it normally
just inserts a block in to a 'null' composition. There is a certain
amount of skill in using it, but 7 parts of Surprise Major are among the
Having said that, the 45 method composition in question was pushing it
to the limit. I starting by trying to create a neat composition along
the lines of Norman Smith. When I'd got something that looked quite
nice I used that as the base composition. I extended the list of lead
heads that were allowed and searched again. Eventually this produced a
block containing all the remaining methods that could be inserted in to
the first block. Only one answer came up, though if I'd left it going
longer there probably would have been more. I doubt the whole process
took more than an hour or two. (I'm not very patient when it comes to
composing). Anyway, that explains why the composition has a neat
section, and a more random section with singles.
