UNESCO status for bell ringing? That's an interesting analysis . My comment was based on a general impression rather than hard data. However I do know that in 2024 50% of our branch members never attend any of the 50 or so practices that we ran (elementary, imtermediate, advanced, Saturday, weekday afternoon) and in 2017 30% of members hardly ever rang at all (in their own towers).
It would be interesting to know how other areas break down motivational aspects (though Roger's categories aren't quite how I would break down ringers round here).
I think Roger might be over estimating the degree of attachment to service ringing. It is what we have all grown up with as the dominant form of performance, so we accept it as normal, but that doesn't mean they identify with it. I took a straw poll of what ringers would do if ringing at their church ceased and the options available were: (a) ring at a secular tower, (b) travel some distance to a church with service ringing or (c) give up. Of the 30 people who replied 80% said they would ring at a secular tower rather than travel to find service ringing.
On a tangential point - while service ringing is indeed a Victorian invention Ellacombe's early writing when he was formulating his ideas in Bittern in the 1820s suggest that he didn't want ringing for services (hence the eponymous apparatus). He encouraged his ringers to practise twice a week and to attend services but I don't thionk they rang for them. I think it was later, probably with the influence of the Oxford Movement, that service ringing was being promoted. It's in the rules of the GDR, which Ellecombe founded, but that was 50 years later, and it could well have been the other, younger reformers who introduced the idea.
