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.”

Sneaky “Salicus” Statements by Solesmes

Jeff Ostrowski · March 18, 2023

HE WORLD-FAMOUS 1961 edition of the LIBER USUALIS—having first reproduced the PREFACE of the official edition—makes this statement: “The place of honour in this Solesmes Edition of the Vatican Official text is given to the Vatican Preface. Its wise counsels and general Principles of interpretation are embodied, elucidated, and enlarged upon in the RULES given further on.” It gives me no pleasure to say it—and makes me rather uncomfortable—but this is a deceptive statement.

Deceptive Statement • Their rules do not “embody, elucidate, and enlarge upon” the Editio Vaticana rules. Rather, the monks of Solesmes obfuscate and contradict the Editio Vaticana rules. Let us consider the SALICUS. According to the official edition, the SALICUS is distinguished from the SCANDICUS by a (very narrow) blank space after the first note. The following is taken from the official edition:

Please note: It’s almost impossible to recognize a SALICUS in editions which are printed in tiny fonts. On the other hand, the SALICUS is incredibly rare the official edition.

At first, Dom Mocquereau adopted this “blank space” to differentiate the SALICUS from the SCANDICUS. Here is what Dom Mocquereau wrote in December of 1905, when they first released the “Solesmes version” of the Editio Vaticana KYRIALE:

The English version by Dom Mocquereau—which also appeared in December of 1905—says:

Observe the difference in the old notation between the SALICUS and the SCANDICUS. The first note of the SALICUS is separated from the next note, which means that the ictus is on the second note, not on the first, as in the SCANDICUS.
Prior André Mocquereau (December 1905)

To banish all doubt, Dom Mocquereau added a little note right before he signed his PREFACE:

N.B. Blank spaces in this edition never indicate morae vocis, but only the separation of groups, except the space after the first note of a SALICUS, whereby it is distinguished from the SCANDICUS.
Prior André Mocquereau (December 1905)

Deception Enters In • However, the Solesmes monks got in trouble with the Vatican for modifying the official edition. In an attempt to get in less trouble, Dom Mocquereau decided to ‘detach’ his rhythmical signs from the notes. But this caused a crisis when it came to the SALICUS, so Dom Mocquereau decided that—as far as he was concerned—the SALICUS would henceforth be differentiated by a vertical episema (“tick mark”). The 1961 LIBER USUALIS suggests that Dom Mocquereau would have preferred to use a horizontal episema—but that proved “too difficult to write,” as they explain in the introduction:

But Wait … There’s More! • Are you confused yet? Even more deception enters in. When the Solesmes monks printed their “rules” in 1921, they pretended there was extra “blank space” in the example they gave. In other words, they pretend like they are merely clarifying what is already a SALICUS in the official edition.

What they are doing is introducing a SALICUS where none exists. Indeed, they do this hundreds of times. The SALICUS is extremely rare in the official edition, but one would never know that if one uses Dom Mocquereau’s editions:

A Bizarre Aberration • We have seen how the 1961 LIBER USUALIS (most likely written by Dom Gajard) claimed that Dom Mocquereau would have preferred to have a horizontal episema for the SALICUS “but it was too difficult to write.” If one looks at the 2 February ALLELUIA, one will see this statement contradicted:

Specifically, one sees horizontal episemata which constitute an anomaly:

I have often remarked that the Abbey of Solesmes never changed any of the ICTUS markings that Dom Mocquereau added in 1908, even in their most recent ICTUS publications (such as the 2014 Gregorian Missal). But if one examines that 2 February ALLELUIA, one notices that later on they added several instances of the SALICUS which Dom Mocquereau had not.

Patrick’s Assertion • In a recent article, my colleague Patrick Williams made the following assertion about your humble correspondent:

Below are the precise words of the document issued under Pope Pius XII (3 September 1958):

The signs, called rhythmica, which have been privately introduced into Gregorian chant, are permitted, provided that the force and meaning of the notes found in the Vatican books of liturgical chant are preserved.

Clear As Day • Is there anyone who would be willing to claim (publicly) that Dom Mocquereau’s modifications “preserve the force and meaning” of the notes of the official edition? Can this be maintained, for example, when it comes to the billions of illicit elongations in the February 2nd ALLELUIA we examined above? Oh, surely not!

To put it another way, making every other note twice as long (or three times as long) is clearly not preserving the “force and meaning” of the notes. Notes have a meaning. Were that not so, somebody could publish an edition like this:

Such an edition would certainly reproduce correctly the pitch of each note; but it would not have been viewed as “preserving the the force and meaning” of the notes of the official edition.

    Music List • (5th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 5th Sunday of Lent (22 March 2026). If such a thing interests you, feel free to download it as a PDF file. Traditionally, this Sunday was called ‘Passion’ Sunday. Starting in 1956, certain church leaders attempted rename both ‘Passion’ Sunday and ‘Palm’ Sunday—but it didn’t work. For example, Monsignor Frederick McManus tried to get people to call PALM SUNDAY “Second Passion Sunday”—but the faithful rejected that. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Music List • (Holy Thursday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Holy Thursday, which is 2 April 2026. If such a thing interests you, feel free to download it as a PDF file. I’m not sure I’ve ever heard a more piercingly beautiful INTROIT, and I have come to absolutely love the SATB version of ‘Ubi cáritas’ we are singing (joined by our burgeoning children’s choir). I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    “O Escam Viatorum” • (Holy Thursday)
    When I was very young, I erroneously believed the four psalms provided by the 1957 Liber Usualis—for Communion on Holy Thursday—were the “correct” music to sing on that first day of the TRIDUUM SACRUM. Those four psalms are: Psalm 22 (Dóminus regit me et nihil mihi déerit); Psalm 71 (Deus judícium tuum regi da); Psalm 103 (Bénedic ánima méa); and Psalm 150 (Laudáte Dóminum in sanctis ejus). It turns out I was way out in left field! While nothing forbids singing those psalms, many other options are equally valid. Our volunteer parish choir will sing this COMMUNION PIECE (joined by our burgeoning children’s choir) on Holy Thursday during Holy Communion. Needless to say, this will happen after the proper antiphon from the GRADUALE ROMANUM has been sung.

Quick Thoughts

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    Stumped by “Episcopalian Hymnal” (1910)
    Some consider Songs of Syon (1910) the greatest Episcopalian hymnal ever printed. As a Roman Catholic, I have no right to weigh in one way or the other. However, this particular page has me stumped. I just know I’ve heard that tune somewhere! If you can help, please email me. I’m talking about the text which begins: “This is the day the Lord hath made; In unbeclouded light array’d.” The book is by George Ratcliffe Woodward, and its complete title is: Songs of Syon: A Collection of Psalms, Hymns, and Spiritual Songs. Back in 2016, Corpus Christi Watershed scanned and uploaded this insanely rare book. For years our website was the sole place one could download it as a PDF file.

    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

“Abbat Pothier’s great accomplishment is having returned to the Catholic world—along with the traditional melody—the traditional way of performing it. The foundations laid by this providential man have been accepted by all those who practice Gregorian chant.”

— Dr. Peter Wagner (Commissionis Pontificiæ Gregorianæ Membrum)
