"Morfa Rhuddlan"
 (The Marsh Of Rhuddlan), the now mostly-drained great sea-marsh (morfa) around Rhuddlan, at the mouth of the River Clwyd. It was the scene of a great battle which has lingered in the local folk memory (the lament of 'Morfa Rhuddlan' is one of the oldest surviving pieces of native music) but this took place in 796 CE when the forces of Offa crushed the Welsh.

Although likely written originally for the Welsh bagpipe, I arranged this piece for Concert (Pedal) harp duet and is best played using the "GeneralUser GS.sf2" Soundfont by S. Christian Collins Software (http://www.schristiancollins.com/generaluser.php).
