PDF Download: Mocquereau’s 1903 “Liber Usualis”

Jeff Ostrowski · July 25, 2014

AY BACK in 2007, Watershed began uploading hundreds of liturgical books which were freely downloaded by Church musicians everywhere. Many of the books were (and remain) extremely rare. One of the most important books we uploaded in 2008 was a complete copy of Dom André Mocquereau’s 1903 Liber Usualis. It seems that archive.org has followed our lead. More than half a decade later, they have scanned their own copy of Mocquereau’sbook, and made it available as a PDF file.

Surprisingly, their scan was poorly done—whereas archive.org usually does a fantastic job. In fact, the Watershed PDF is of a higher quality:

*  PDF Download • Solesmes Liber Usualis (1903) — «Paroissien Romain»
—The 1903 Liber Usualis of Dom André Mocquereau.

Liber usualis, Missae et officii
pro Dominicis et festis duplicibus:
cum cantu Gregoriano

Publisher = Romae: Descleé, Lefebvre & Soc.
Typis Societatis S. Joannis Evangelistae

THIS BOOK WAS Mocquereau’s great masterpiece, and it still excellent for reference purposes. Many of his variants are more beautiful than those found in Pothier’s Editio Vaticana, such as the 1903 version of Ut Queant Laxis.

Quick Thoughts

PDF Download • Trinity Sunday (22 pages)

Feel free to download this Organ Accompaniment Booklet for Trinity Sunday (Second Vespers). Notice how the modes progress by number. Psalm 1 is mode 1; Psalm 2 is mode 2; Psalm 3 is mode 3; Psalm 4 is mode 4; Psalm 5 is mode 5. I am told by an expert that other feasts (such as Corpus Christi) are likewise organized by mode, and it’s called a “numerical office.”

10 June 2022 • “Official” rhythm of plainsong

I continue to search for the most beautiful way to present the “pure” Editio Vaticana scores. (Technically, the “pure” rhythm of the official edition is what everyone is supposed to use.) You can download my latest attempt, which is the Introit for this coming Sunday: Feast of the Most Holy Trinity. Because this is not an ancient feast, the Introit had to be adapted (perhaps around 750AD). Prior Johner says the adaptation is “not an entirely happy one.”

7 June 2022 • FEEDBACK

From Chelan, Washington: “CCWatershed is a God-sent resource that I can’t function without! Such great work by the team to bring beauty back to our liturgy!” From Gainesville, Florida: “I am so appreciative of the work, of my brothers and sisters in music!” From Troutman, North Carolina: “Keep up the excellent work in service of the Liturgy!”

Random Quote

“Some of our younger parish clergy read their sermons. This should not be done except for some very special reason. The priest who is not capable of preparing and delivering a brief, clear instruction on Catholic teaching to his people is not fit to be in parish work. The people as a rule do not want to listen to a sermon reader.”

— Archbishop of Baltimore (9 July 1929)
