some of the repertoire is the same. i posted an article on English fiddling,did you read it?
it put fprward the suggestion that decoration had been more prevalent in the past.
   As to the repertoire, imo the harmonic construction of irish music, is more varied than southern english folk music ,much of which ios in the major keys, in the donegal and northumbrian[english] repertoire there is more scottish influence,
in fact the irish reel tradtion has scottish influence, some of the tunes were originally Scottish, there is an influence in the hornpipe tradtion, some of the tunes being written by a Scotsman who lived in northern England Newcastle James Hill.
Perhps you PREFER tunes in major keys.
I used to know a man who only liked baked beans and ate very little else , he is still alive, he has produced several children and is now a senior citizen
Taste is very personal
