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.”

Revisiting Musicam Sacram

Fr. David Friel · March 8, 2017

UNDAY marked the fiftieth anniversary of Musicam sacram (MS), the 1967 instruction on sacred music crafted by the Consilium for the implementation of Sacrosanctum Concilium. To prepare for this occasion, I reread the document (available here) and wrote an article that has been featured as the lead story in the latest edition of Altare Dei. Available here, Altare Dei is a new magazine devoted to liturgy and sacred music.

My article is entitled “Revisiting Musicam Sacram: The Second Vatican Council’s Vision for Sacred Music,” and it has four main sections. First, it addresses the question of whether or not MS is still in force. Secondly, it assesses some of the strengths of the instruction. Thirdly, it reflects upon a few of its weaknesses. Finally, it explores the meaning of “progressive solemnity,” a term which first appears in MS 38.

Following are two excerpts from my article. The first concerns some of the strengths I observe in MS:

There are many very fine aspects of this document. Some of its best elements, though, even fifty years later, still have not been wholeheartedly received or implemented. Greater attention to the encouragements and prescriptions set forth herein would almost certainly advance the state of sacred music. Included in this Instruction, for example, is a directive that pastors should cultivate among the faithful the ability to sing the ordinary of the Mass in Latin (MS 47). Although this noble mandate echoes the desires of SC 54 and IO 59, it has nonetheless often been overlooked. Preserving the use of Latin in the Divine Office, particularly among clerics, is also encouraged (MS 41), although this guidance is widely disregarded.

The second excerpt concerns what I perceive to be a weakness of MS:

[One] critique concerns a presumption that is made about the participation of the faithful. The text seems to suggest that a greater variety in the format of liturgical celebrations from day to day will engender more active participation among the people: “In order that the faithful may actively participate more willingly and with greater benefit, it is fitting that the format of the celebration and the degree of participation in it should be varied as much as possible” (MS 10). The presumption undergirding this encouragement, though, is suspect. What evidence is there that constantly changing liturgical structures helps people to “participate” or “engage” more deeply? It could easily be argued that the opposite is actually truer, namely, that constancy in liturgical structures permits people the freedom to participate deeply.

In order to read the full article, click here to download the third issue of Altare Dei. For only €6, you will receive a 10-page musical insert and a wealth of excellent articles by such scholars as David Fagerberg, Peter Kwasniewski, and Joseph Shaw. The musical insert includes an SATB setting of Adoro Te Devote (Mauro Visconti), a unison setting of Ave Maria with organ accompaniment (Aurelio Porfiri), and an expressive SATB version of Laus tibi Domine (Colin Mawby).

You can also find out more on the Altare Dei website about the recently published Declaration on Sacred Music, Cantate Domino Canticum Novum. The text is available for download in eight languages, and the complete list of signatories is given.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    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

“In the 17th century came the crushing blow which destroyed the beauty of all Breviary hymns. Pope Urban VIII (d. 1644) was a Humanist. In a fatal moment he saw that the hymns do not all conform to the rules of classical prosody.”

— Fr. Adrian Fortescue (d. 1923)
