Reviews

"This important publication increases the accessibility of a less-well-known medieval treatise on music theory devoted to the Gregorian chant repertoire for Mass and Office. [...] This welcome new edition and English translation of the Tractatus by a team of Australian scholars introduces the treatise by identifying the sources of Guy's teaching, sketching the history of his abbey in the late thirteenth and early fourteenth centuries, and exploring the treatise's relationship to the Cistercian and Dominican chant traditions." Joseph Dyer, The Medieval Review 18.03.18
