Textbook of Gregorian Chant according to the Solesmes Method (1930)

By compressing the Solesmes teaching within the narrow limits of a general textbook, Dom Sunol has rendered good service of the Gregorian cause. It was prepared under the direct supervision of the Solesmes Benedictine Fathers at Quarr Abbey, who supplied invaluable help on almost every page, mainly in the direction of ensuring greater accuracy, clearing up obscure passages, simplifying technical points and generally making the book more accessible to the ordinary student of plainsong.
