The MacArthur-MacGregor Manuscript of Piobaireachd contains thirty compositions for the Highland bagpipes for use on ceremonial occasions, compiled by the pipers Angus MacArthur of Trotternish in Skye and John MacGregor of Fortingall in Perthshire, and overseen by Andrew Robertson of the Highland Society of London. This Piobaireachd Society manuscript [deposited in the National Library of Scotland] is published here for the first time in a volume comprising extensive background material, critical and performing editions of the music, and a facsimile of the original music pages. FRANS BUISMAN [1942-2002] spent his working life cataloguing oriental books at Amsterdam University and devoted the rest of his time to the classical music of the great Highland bagpipe. ANDREW WRIGHT is one of the world's foremost performers, teachers and adjudicators of ceòl mór, the classical music of the Highland bagpipe. Formerly Reader in Chemistry at the University of East Anglia, RODERICK CANNON is also a piper and author of several books about the history of bagpipes and their music.
