Before coming to the Music Program in 1976, Dr. Gillingham held posts at universities in Newfoundland, New Brunswick and Alberta. He has been very active as a scholar, editor, publisher, and director of various departmental performance groups (early music and choir). His books include monographs on various aspects of twelfth- and thirteenth-century music (e.g., Modal Rhythm, Medieval Polyphonic sequences, St. Martial Mehrstimmigkeit, a trilogy of books on Secular Medieval Latin Song) facsimile editions, and articles appearing in various British, American and Canadian journals. For some years, he was co-editor of Dovehouse Editions, an enterprise which produced some 55 editions of Renaissance and Baroque chamber music. Dr. Gillingham also served as director and general editor for the Institute of Mediaeval Music.(http://www.medievalmusic.ca) This publishing house produced about 120 books during his editorship.
His numerous travel and research grants have enabled him to study in many European libraries. He has also presented papers at conferences in Europe, the United States and Canada and served in various capacities for the Canadian Federation of Humanities, the World University Service, and the Association of Universities and Colleges of Canada.
Dr. Gillingham retired from Carleton University on July 1, 2009.
