But this kind of thinking about canons pretends that the canon is a “thing” that sits out there in the world — which is still a question of “how and why” a canon exists.… But if that was all that canon meant — “the stuff that we think should be self-evidently important to everyone” — then canon would be a useless word.
Of course I don’t write about music. From the outside, I have to say it does look very very much like a useless word in the context of music writing - or at best badly appropriated. The (to me) inherent sense of canonicity has been dropped.
Having said that, I get ticked off enough at people who complain about ‘inappropriately appropriated’ (HA!) words like ‘trope’ - get used to meaning change pplz.
The original usage that kicked this off (ie wrt NPR [whatever that spells]) was about how the reaction to the blog was like the reaction to heresy (and laziness and etc), so I interpreted it as being a last (maybe unnecessary for music writers, but useful for the pub at large) kick at the zombie corpse of the THE in “the canon”.
