BYROC Method Libraries

In this directory you will find method libraries suitable for use with the programs BYROC and BYROC MINOR. The libraries will only be useful to you if you have purchased one of these programs. The method libraries are derived from the Central Council Metthods Library (which is the copyright of the Central Council of Church Bell Ringers).

BYROC, or "be your own composer" is a program for change-ringers on church bells (or handbells). It has been developed to provide bellringers with ready access to a great variety of compositions for most Major, Royal and Maximus methods. BYROC can be used for any treble-dominated method with a symmetrical structure about the half-lead. Compositions are restricted to keeping the tenors together, although common twin-call arrangements such as In/5ths, 5ths/4ths, s3rds/s5ths are permitted in compositions for methods having an appropriate lead head. BYROC will generate touches up to normal peal length, but is not suitable for very long lengths. BYROC MINOR produces 6-bell touches.

BYROC was produced by David Beard, who sadly died early in 2004.

To use the libraries in this directory, you can either download the file "", which contains all the method libraries in compressed form, or simply download the individual files that you need. Copy or extract the files into your BYROC directory. The name of each file is in two parts: (1) Method class and (2) number of bells. The method classes are:
A - Alliance
D - Delight
P - Plain
S - Surprise
T - Treble Bob
TP - Treble Place

The numbers of bells are:
MIN - Minor
MAJ - Major
ROY - Royal
MAX - Maximus
(So, for example, SMAJ contains Surprise Major methods)

Library files only exist for the classes and numbers of bells that BYROC is able to use, so, for example, there are no 14 or 16-bell methods because BYROC only supports a maximum of 12 bells.

These libraries were produced by Julian Morgan ( The production of these libraries was not an official Central Council activity. If you wish to comment on any of the method data, please contact
