The Monastic Diurnal Noted is a complete Gregorian Antiphonal in English, containing all the Antiphons, Hymn Tunes, and Responsories of the Day Hours of the Benedictine Divine Office (the seven canonical Hours, excluding the midnight office of Matins).
This high quality reprint combines the two original volumes into one single volume. The first volume includes the music of Vespers, the Little Hours and Lauds of Great Feasts. The second volume includes the music of Sunday and Ferial Lauds, with Matins of the Sacred Triduum and Matins of the Dead.
The Monastic Diurnal Noted is the brilliant work of the Reverend Canon Winfred Douglas, the renowned English church musician and pioneer of adapting Gregorian plainchant to English. Both volumes were prepared posthumously by the Sisters of the Community of Saint Mary. This reprint is a photographic reproduction of the original editions of 1952 and 1960.
Second, the St. Dunstan's Plainsong Psalter to go with the MDN:
SAINT Dunstan's Plainsong Psalter is the culmination of three full years of research, compilation, and proofreading. It is the first traditional English plainchant publication to be in print for many decades. Moreover, it is the first publication of its kind to include all elements necessary for the recitation of the Daily Offices of the classic Book of Common Prayer according to the ancient Gregorian chant tradition. Saint Dunstan's Plainsong Psalter was produced jointly by Western Rite Orthodox and traditional Anglican scholars and editors, and it may also be of interest to Roman Catholics (especially of the "Anglican Use") as well as by Protestants who appreciate the classic English biblical texts and the plainchant tradition.
