Thje harp addition to the Shetland music was interesting. The sort of "Celtic twilight" spin that has been applied to most Scottish and Irish music(witht the glorious exception of the Dubliners) has mercifully not reached the Shetlands(like the Gaels!). So I was a little disappointed by this aspect of last night's broadcast. I love harps, but in this case it was not just a harp. It was an editorial intrusion, a piece of ersatz "Celticisation" based on the modern image of the harp, not its actual history or music.
There is nothing distictively Celtic about harps, any more than there is anything Celtic about bodhrans, but they can be manipulated into appearing so.
