I've written a post for the Culturekicks.co.uk site about why we need urgently to address the issue of language for talking about music. The term "dumbing down" is essentially a misnomer: a more correct term is "de-skilling". With a whole generation forcibly removed from musical literacy and terrified of learning the necessary bits and pieces - however easy they really are - how are we to keep talking about music at all?

Culturekicks, btw, is created by the same team that used to run the late lamented and daftly dumped Spectator Arts Blog, and it has kept the latter's archive of brilliant posts by brilliant writers...including yrs truly. More power to their elbows.
