And do you also subscribe to the term Celtic Music, that there is a similarity in the music of the Celtic Fringe because of a Celtic spirit imparted by the genes. Or is the similarity just due to the fact that the Celtic countries are neighbouring.

I don't fail to see joy,sadness and exuburance in Reinhardt's music but I don't put it down to his ancestry but to his culture (that is apart from his particular genius). His musical influences were mostly from the people around him and not from 600 miles away. As for getting about about a bit I suspect international travel wasn't that common in the early 20th century.

BTW, doctrinaire means "Seeking to impose a doctrine in all circumstances without regard to practical considerations". Practical considerations...It doesn't mean having a different point of view to you.
