A notable event for parishes and communities who want to celebrate the modern Liturgy of the Hours in Latin : the complete edition of all the Gregorian melodies for the texts of the day hours of the Liturgia Horarum.
An immense and complex undertaking, with a practical design
Until now, there has been nothing like this anywhere : it is officially a veritable Latin-French [What a boon it would be to have this in Latin-English] antiphonary, containing everything you need for the Office of the day in three volumes (two temporal, one sanctoral). It will offer a convenient way to sing the Office in the Ordinary Form in Latin.
Les Heures Grégoriennes are a collaborate effort between the Community of Saint Martin, (conception, research, editing), the paleography workshop of the abbey of St. Pierre de Solesmes (the critical edition of the Antiphonale Romanum), and the abbey of St. Joseph de Clairval–Flavigny (the long hours of tedious layout design).

1. Latin Psalter of the Liturgia Horarum (2000 edition)
2. Gregorian notations edited by Saint Pierre de Solesmes Abbey
3. Liturgia Horarum compliant antiphons
4. Polychromatic liturgical edition
5. French translation for liturgical use
A very attractive pricing
The four volumes of the roman Liturgia Horarum currently cost 61€ each (US$98) in the economy (vinyl) edition. In addition, one must purchase various chant books for the melodies.
The total price for a set of these three volumes will be 195€ (US$310). There is a reduced rate of 165€ (US$262) if you subscribe before 31 May 2008.
Rediscovering the musical heritage of the Roman Rite…
This book is simply the implementation of the requests of the Holy Father and the directives of Vatican II. The Council, in the liturgy constitution Sacrosanctum Concilium, ‘canonized’ a musical repertoire as the proper chant of the Roman Rite for the first time in its history. The Council went on to order the books of Gregorian Chant be revised and new editions prepared. This is exactly what the Community of Saint Martin has done in the midst of our Holy Father Benedict XVI’s encouragement of the blossoming of a ‘new liturgical movement.’ We should mention that those responsible for this project have requested approval (editio “iuxta typicam”) from the Sacred Congregation for Divine Worship, and the Prefect of the Congregation, Francis Cardinal Arinze, has given his very enthusiastic endorsement with a wish that everyone will make good use of this work.
About the Community of Saint Martin…
Launching a new edition of the Gregorian melodies for the Ordinary Form of the Roman Rite is a bet for the Community of Saint Martin. By way of background, this community of priests, founded by Monseigneur Guérin in 1976, has had a profound intuition : to live in community as diocesan priests and deacons at the guidance of bishops, while serving in pastoral ministry. And in this community life, most often in a parish, the liturgy has a central place whether in Latin or in French, but always in the Ordinary Form of the Roman Rite.
