About the Breviarium Gregorianum Project

About

Breviarium Gregorianum groups together the Gregorian scores of the Divine Office according to the Catholic Breviary in force in 1962. The scores come mainly from the Liber Antiphonarius and the 1961 Liber Usualis published by the Abbey of Solesmes.

It is still in an early beta, not everything is implemented for the 6 available offices and Matins and Complines are not yet available. Please consider donating if you want to support the development of the project.

Breviarium Gregorianum was designed and coded by myself, Yanis Ouakrim, PhD student. It is mainly aimed for the prayer of the Divine Office at the Collégiale Saint-André in Grenoble by a group of laymen led by Thierry J..

It is a friend project of Vespero Generator that provides vesper booklets for all the main feasts and sundays of the 1960 breviary.

Breviarium Gregorianum relies on other projects namely:

• Divinum Officium, for all the texts and the ordo of the offices and part of the rubrics.
• Gregobase, for all the chant scores.
• Chant Tools, for the notated psalmody and chapters.
• Exsurge.js, for the rendering of the GABC.
