The pipes and the kingdom belong to different eras - the Northumbrian pipes reached something like their modern form in a similar time and place to the steam locomotive.
But they were called 'Northumberland pipes' then, as were their simpler 'unimproved' pre-Peacock version. 'Northumbrian' is now used, confusingly, to refer to any of -the Anglo-Saxon kingdom -the modern county -the modern NE region, from the Tees to the border, never ever specifying which is meant. It is apparently a gross error to do so, though I never understood why.... John -- To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
