ANY PEOPLE THINK think they need the Liber Usualis, but might actually prefer the Graduale if they knew about it.
Anyway, here’s an online PDF copy of the 1961 Liber Usualis published by the monks of Solesmes:
If you like the Liber Usualis, you should download the 1957 version that includes English Translations:
The Liber Usualis is (of course) the “Vatican Edition” (Editio Vaticana), but with rhythmic signs added by Dom André Mocquereau in 1908 (and not one of these marks was ever changed in a subsequent edition, even 100 years later). If you don’t understand what the “Vatican Edition” is, please watch these videos.
• 1961 Edition of the Liber Usualis by the Benedictines of the Solesmes Monastery • The Liber Usualis contains the complete Latin settings of Gregorian Chant for every Mass of the year (Sundays, Solemnities, Commons and Feasts) as well as for Nuptial Masses, Requiem Masses, Holy Week, and Ordination. Additionally it provides much of the Gregorian Chant to be sung in Latin for the Divine Office (Vespers, Compline, etc.), as well as many other traditional Latin chants and hymns (Litanies, Benediction, etc.). • Gregorian Chant for Every Mass of the Year • There’s no such thing as a “1962” Liber Usualis, because the 1962 Liber Usualis is identical to the 1961 version •
