Ringing Forums

In 2014, Christchurch and Southampton District carried out a survey of members, with 85 responses. The median ringer in that group was in the process of learning their 2nd method, which at that time was most likely a 2nd doubles method, not Bob Minor.
The median age at that time was 62. A fact which I think shocked the District into doing a lot of active recruitment.
One unexpected result was that ringers who were recruited post-1980 were (very) significantly less likely to have mastered any Surprise methods.

I have never met anyone who is so focussed on the sound of methods to the complete exclusion of understanding the written notation, but I would confess to sharing your learner's awareness of the tunes of plain courses and bob courses of Grandsire. If I am not careful, I zone out and realise I am simply ringing the tune rather than concentrating properly on where I am.

Hopefully, your learner's understanding of blue lines will develop over time, but meanwhile, she needs to start her journey from where she is. A copy of Abel on her computer will enable her to listen repeatedly to simple touches of methods and memorise them, so that she can progress and learn new things. She can also "ring" one of the bells and find out how well she is ringing, from the score at the end of the piece. I find that very useful as I can judge whether it is worth trying a method on practice night.
Using an app such as methodology on her phone will at least enable her to memorise plain courses of new methods.

In time, she may get frustrated because I suspect that it is impossible to memorise a longer touch; but having said that, perhaps it isn't impossible, and there is a future in which she becomes a conductor, who can memorise whole peals and quarters, calls and all?

If your learner finds eventually that she really wants to understand written notation for methods, then I would encourage her to watch Abel ringing things she knows well, but slowed right down, so she can see the relationship between the numbers on the screen, and the sounds she can hear.
