Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

Jeff Ostrowski · September 10, 2020

WO YEARS after Dom Joseph Pothier left Solesmes to become Prior of Ligugé, the LIBER RESPONSORIALIS (1895) was published, which was entirely the result of Pothier’s research. In addition to those parts of Matins which don’t change, it contains first class feasts and the Common of the Saints: martyrs, confessor bishops, virgins, and so forth. This book is only for Matins, but the hymns are often repeated at Vespers. We were recently sent a rare book which seems to consist of excerpts from the LIBER RESPONSORIALIS. (Perhaps an expert on the Divine Office can let me know whether it contains anything the Liber Responsorialis does not.)

We thank the donor who sent us this book from 1928:

The “invitatory” occurs at the beginning of Matins and therefore introduces the daily divine Office. The invitatory proper is the anthem or response, which is interspersed with the verses of Psalm 94 (Venite exsultemus Domino), the invitatory psalm. Note that the whole invitatory anthem is sung before some of the verses of the psalm, and the second part only before other verses.

I must admit I’m puzzled that Solesmes Abbey (via the Belgian Desclée brothers printing house) felt the need to produce such a book. My understanding is that the office of Matins is very rarely sung, even in the strictest of monasteries. When it is sung, it is usually done “recto tono.” I am told there was a tradition of secular clergy singing Matins for the feast of Christmas—and perhaps for some other great feasts—but as far as I know, seculars would usually recite Matins (and Lauds) privately.

In any event, it’s an interesting book. Composers of “English Plainsong” should make themselves aware of these tones, which are quite beautiful.

Here are some photos of the INVITATORY (1928):

And here are some photos from the LIBER RESPONSORIALIS (1895):

Full title of book: Invitatoria cum psalmo Venite exsultemus per varios tonos pro officiis de tempore et de sanctis. Typis Societatis S. Joannis Evangelistae • Desclée & Socii • S. Sedis Apostolicae et S. Rituum Congregationis Typographi • PARISIIS, TORNACI, ROMAE +

MENTIONED that the INVITATORY consists of excerpts from the LIBER RESPONSORIALIS (1895), which contains the pre-Urbanite hymn texts (i.e. “non-corrupted”), just as Dom Pothier had used the pre-Urbanite hymn versions in his 1891 Liber Antiphonarius. For instance, in the 1895 Liber Responsorialis we find “Praelium certaminis” instead of “Lauream certaminis” in Fortunatus’ Pange Lingua. About a decade later, in September of 1904, the Pontifical Commission for the Vatican Edition would adopt the following motion:

22. The Congregation of Sacred Rites shall be requested to return to the medieval text of the Hymns (a.) because the text corrected by Urban VIII is ill-suited to the needs of the chant; (b.) in consideration of the artistic unity of the whole of the liturgical work; and (c.) out of respect for the ancient and holy authors of a great portion of these chants.

They were not granted permission at that point, but some publishers included the ancient texts as an option. Indeed, any priests or monks or nuns who sang the Divine Office had never adopted the Urbanite revisions. For instance, the major Roman basilicas never adopted the revisions of Urban VIII; nor did the Benedictines.

To learn more about “pre-Urbanite” hymn texts, please obtain the Brébeuf hymnal, which has a color-page section explaining the subject in detail, with much original research:

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

Random Quote

We cannot exaggerate our indebtedness to Dr. Julian’s “Dictionary of Hymnology,” a monumental work, without which we could not have reached the high standard of accuracy, as to both texts and authorship, which we set before us when entering upon our labours.
