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.”

PDF • “Ecclesia Dei” Responses (14 November 2018)

Jeff Ostrowski · November 28, 2018

87023 Commission “Ecclesia Dei” Responses (14 November 2018) ATHER DAVID PIETRAS, a Polish priest, wrote to the Pontifical Commission “Ecclesia Dei” three months ago with twenty-nine (29) questions about the Traditional Latin Mass. The reply, dated 14 November, was posted anonymously on the CMAA forum.

Several questions deal specifically with Gregorian chant and music in the Extraordinary Form. The Dubia of Father Pietras (24 September) uses very poor English and—unless I am very much mistaken—was originally written in Polish. 1

The 24th question is garbled and self-contradictory:

Question 24: During the Mass, in the Extraordinary Form of the Roman Rite, Gregorian chants performed using a different method than the Solezmian method provided for by the Graduale Romanum (1961) are acceptable? In particular: (1) the semiological method of Eugene Cardine’s house (eng. Semiology, “Gregorian’s Semiology”; House Eugene Cardine); (2) singing method by Marcel Peres (vocal technique based on eastern {especially Croatian} practice used widely by Marcel Peres and his students); (3) using Graduale Romanum 1908, omitting rules and regulations regarding the technique of singing the Gregorian chant prescribed in the Graduale Romanum 1961.

Ecclesia Dei Response: “Affirmative.”

… but the question makes no sense.

Fr. Pietras asks whether the Solesmes rhythmic method of 1961 must be used. Those who attended the 2018 Symposium realize that (technically) the Solesmes rhythmic method of 1961 is not allowed by the official decrees of the Church. Private rhythmic methods (such as the 1961 Solesmes) were tolerated so long as they don’t contradict the official Vaticana rhythm. 2

87024 De musica sacra 1958


This was explicitly written in §59 of De Musica Sacra, issued under Pope Pius XII (3 September 1958). The “rules and regulations” of the 1961 Graduale—to which Fr. Pietras makes reference—are not the official rules. The official rules are in the 1908 Graduale, as we have explained many times. Technically, the Solesmes rhythm is not allowed—because it frequently contradicts the official Vaticana rhythm—but the CSM (“Classical Solesmes Method”) has become so popular over the last 120 years, it seems foolish to oppose it. The NOH attempted to oppose it in the 1940s, using the official rules which (by law) are printed in the front every Graduale. An English translation of those rules can be found here. 3

To be clear, I am not attacking Fr. Pietras for being confused; the whole situation is rather esoteric. It took me several years to fully grasp it.

By the way, Fr. Pietras claims the method of Marcel Peres is “widely used.” I believe he’s mistaken; it’s not widely used. Moreover, he makes reference to a “singing method” of Dom Cardine—yet Cardine repeatedly made clear he did not leave a particular system, and in his Last Will And Testament (1984) reiterated again that semiology “is not a method.”

The 27th question is also quite garbled, and difficult to understand:

Question 27: Is the female solo singing allowed during the liturgy in the Extraordinary Form of the Roman Rite, in connection with the instruction of Musicam Sacram published in 1967? The Sacred Congregation of Rites, in reply to the “On July 10, 1959,” for dubia regarding the Instruction De musica sacra from 1958 (questions were asked by Alojzy Carli, bishop of Segni), she ruled that solo singing should not be performed by a woman (No. 3-4).

Ecclesia Dei Response: “This Pontifical Commission would not be opposed to this where the practice exists.”

Fr. Pietras seems to inquire whether a female can sing a solo during the Extraordinary Form. Ecclesia Dei says yes; but it would have been better if the person asking the question had specifically asked whether operatic solo singing is allowed.



NOTES FROM THIS ARTICLE:

1   For example, when Fr. Pietras makes reference to “House Eugene Cardine,” he is probably attempting to speak of the Cardine school.

2   The official Vaticana method never really caught on. For one thing, the morae vocis are frequently ambiguous for the singers, especially regarding the Virga. Moreover, the “white notes” are difficult to locate, unless you place your nose close to the bottom of the book spine. John Rayburn wrote in 1964:

The place of the controversial Solesmes editions is clarified by the final paragraph of the 1958 Instruction (De Musica Sacra). It is interesting to note that, for the first time in Vatican decrees dealing with the Solesmes books, a word other than “tolerated” is used; the paragraph cited states that such editions are “permitted.” This is undoubtedly due to the widespread circulation the Solesmes books have achieved in the past fifty years. At any rate, the monopoly held by Solesmes for so long in this country and elsewhere is evidently broken.

Regarding the wording of the 1958 decree, section 59 makes it clear that private rhythmic signs are allowed unless they modify the official edition’s melody. For instance, to add pauses where there are no pauses (or to remove pauses where “white notes” create them) is not allowed precisely because it “alters the melodic line”—and the 1961 Solesmes rhythmic markings do that about 45% of the time. Ictus markings (i.e. counting 1-2-3) is permissible precisely because it preserves the “force and meaning of the notes found in the Vatican books.” However, the CSM (“Classical Solesmes Method”) has been the universally preferred way to perform plainsong for 120 years, and denying this reality would be futile.

3   The Liber Usualis also contains an English translation of the 1908 official rules. However, a few pages later, the editors contradict these very rules!

    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 Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

Quick Thoughts

    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

To end an impropriety, noticed particularly at orchestral Vespers, when two or three Psalms are sung with full orchestra, and then the other Psalms and the Hymn are rapidly hurried through with organ accompaniment only […] we order that at Mass all portions of the text, including “Agnus Dei,” be sung with orchestral accompaniment. […] Moreover, the musicians are not allowed to put the instruments away and leave their places before the conclusion of the sacred function.

— Cardinal Patrizi (18 November 1856)
