This collection is a complete list of the true touches of Grandsire Triples up to 210 changes in length and selected touches up to 364 changes, with an indication of the musical content of each touch. The touches are listed in notation using P for a plain lead, B for a bob lead and S for a single. The touches are in groups of each length, being arranged in order with plain leads first, then bobs and then singles. The musical qualities were assessed for each touch by counting the rows ending in 46, 74 and 67, these three numbers following each touch. Touches containing Queens (1357246), Tittums (1526374) or Whittingtons (1275346) are indicated by Q, T or W respectively. For example, the shortest touch, three consecutive bobs (42 changes) contains two rows ending in 46, none ending in 74 and three ending in 67 (counting rounds once), giving the music code '2 0 3'.
It was originally compiled in 1975, with touches up to 196 changes, using a paper tape system and copies of this collection have been on sale on the Guildford Diocesan Guild bookstall since then. It is an example of the kind of results you can get when you let a computer loose on bell-ringing. Although this collection may look rather daunting at first sight, many conductors have found it a useful way to add variety to their repertoire by picking out a few touches and calling them on practice nights or for service ringing.
