Under the new Central Council Framework for Method Ringing (Section 5.D), a Variation is defined as a named combination of a Method and a Call or Calls. Note that while a variation has the same Class as the underlying Method on which it is based, it does not use a Class Descriptor in its name (for instance, Bob or Place).
The Framework includes the requirement that the Central Council keep a Library of Calls and Variations. This is that Library, although some work is still needed to sort out a few historical anomalies and make sure everything is in consistent with the new Framework. There are also quite a number of duplicate names, which need to be clarified.
The Help section explains how variations are constructed by inserting different calls into a method.
Most of the Variations here are for Doubles Methods, largely because under the previous Central Council Decisions, this was the only Stage at which Variations were defined.
To find details of a particular Doubles variation, either use the quick search below or use the Search by Name link at the top of the page.
Alternatively, you can Search by Structure, specifying either the underlying method or the call (or calls) or both. There is also a single table of all named Doubles Variations, arranged in order of parent method.
A list of all the named Calls used in the Library is given here, with their code letters. You can also use the Search for Calls link above to search the list by name or by other criteria. Help on calls and their code letters is also available.
Many of the variations listed here have had different names or spellings assigned to them over the years. This collection of Debated Names has been compiled in order to show the evidence of various usages. A letter in the Ringing World (1 May 2020, p. 433) requested further information on any of the names.
