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.”

“An Initiation to Gregorian Chant” (Msgr. Turco)

Guest Author · November 26, 2023

Fr. Stephen Concordia, OSB
of Saint Vincent Archabbey
An Initiation to Gregorian Chant
by Monsignor Alberto Turco.

I. How this book came to be
This new book—“An Initiation to Gregorian Chant”—was written by Monsignor Alberto Turco at the request of the Preside (Dean) of the PONTIFICAL INSTITUTE OF SACRED MUSIC (PIMS) in Rome. Aware of the growing number of disciplines involved in the study of plainsong nowadays, the Preside saw the need for an up-to-date yet succinct volume that would provide new students at PIMS with a broad foundation with which they would be better prepared for the formal curriculum in Gregorian chant. He may have recognized, too, an advantage of a book of this type, in that it presents a synthesis of the thoughts of one scholar on many topics about which that scholar has been thinking, teaching, and writing, for a very long time. This book is also the first in a new series of publications by the PONTIFICAL INSTITUTE OF SACRED MUSIC in collaboration with the Libreria Editrice Vaticana (Vatican Editions).

II. Introducing Msgr. Alberto Turco
Monsignor Alberto Turco, of the Diocese of Verona, Italy is a Professor Emeritus of PIMS, Rome. He completed his doctoral studies in Gregorian chant at the Pontifical Institute of Sacred Music in Milan, writing his dissertation under Dom Jean Claire, OSB (d. 2006), the legendary choirmaster of the Abbey of Solesmes. Monsignor Turco remains a devoted disciple of Dom Claire and continues to carry forward Claire’s own research on the science of Gregorian modality. In his home city of Verona, Monsignor Turco founded the Dom Jean Claire Center for the Study of Gregorian Chant and Other Liturgical Monodies. This organization, under Monsignor Turco’s direction, includes a team young scholars, singers, and instrumentalists who have produced numerous CDs and a variety of other publications, e.g., the Liber Gradualis. For decades now, the Jean Claire Center and Monsignor Turco offer summer chant courses throughout Italy, Europe, and beyond. Monsignor Turco, in addition to teaching and regularly publishing his research on Chant, has throughout his life been an active practicing church musician. In 1965, he was named choirmaster of the Cathedral of Verona, resigning only a few years ago. He was one of the original members of the “Nova Schola Gregoriana” founded in the 1960’s by Don Luigi Agustoni. Monsignor Turco assumed the direction at Don Agustoni’s retirement and continues to lead the renowned Schola in concerts, tours, and on recordings. Monsignor Turco founded and directs the Women’s Schola “In dulci Iubilo.” Monsignor Turco, at 85, shows no sign of slowing down.

III. A selection of themes
and author’s points of view in
“An Initiation to Gregorian Chant”

(a.) At the very beginning of his book the author states his perspective on the essence and function of Gregorian chant.

Gregorian chant is the chant of the “Word” of the liturgies of the Roman Church; the chant not of just any word, created by humans, but of the “Word of God”, the chant of the VERBUM who in the fullness of time took on a human appearance: “In the beginning was the Word…and the Word became flesh”. In principio erat Verbum…et Verbum caro factus est (John 1: 1). The primary function of chant, then, “is to be a ‘vehicle’ by which the VERBUM communicates with His people.”

(b.) Prof. Turco asks his students to become well-acquainted with the chant repertory, by which he means to grow in appreciation of the following:

1. the different liturgical-musical forms of Gregorian chant, and the circumstances of their appearance in church history. For example, the liturgical-musical form of the Introit came into being when there was a liturgical need to accompany the entrance of the celebrant (Pope, Bishop) into a Basilica or Cathedral. In earlier centuries, when the Eucharist was celebrated in a private home, or in the Catacombs, there would not have been need for, or even room for the solemn ritual entrance of an Introit.

2. the presence, throughout the repertory, of the three melodic genres of Gregorian chant. syllabic (also known as declamatory), ornate, semi-ornate, and the connection of each liturgical-musical form to a corresponding melodic genre. For instance, the Introit and Communion Antiphons are in semi-ornate genre, while the Celebrant’s prayers, and the readings at Mass are chanted in syllabic, (declamatory) genre. More than one genre can appear in a single chant, as in an Introit or Communion Antiphon. The Antiphon is chanted by the Schola in semi-ornate genre, while the psalm Verse is typically chanted by a soloist in syllabic genre. These are not trivial distinctions, as each melodic genre creates its own distinct relationship to the sacred text.

3. Another distinction observed in the Gregorian melodies illustrates the various compositional procedures employed by the composers of chant. One such procedure is the “melody type” wherein a single melody is used for more than one text– a kind of “recycling” of a melody. The use of melody types would have answered the need for new antiphons in a period of geographic and liturgical expansion of the Church. Other compositional procedures with identical melodies are “modal templates” and “centonizations”. There are “original” melodies as well, in Gregorian chant, without any melodic resemblance to other chants in the repertory.

4. There are three types of Psalmody in the Gregorian repertory, a fact which suggests an historical evolution of Psalmody. The most ancient is Psalmody in directum, typically sung by a soloist, appropriate to a phase in Church history when there were few literate, competent cantors. Responsorial Psalmody answered a different need in the Church, namely, a desire for more participation of the assembly. Antiphonal Psalmody became possible only when a sufficient number of trained cantors were present, as in a mature monastic community.

5. As you may have guessed by now, on most every topic, there will likely be some historical commentary to be made. This is yet another aspect of chant study about which Professor Turco asks for our growing appreciation. As Catholic Church musicians it is, after all, a deepening of appreciation of the history of our work. The importance of the historical perspective is to be expected with a history as extensive as that of Gregorian chant. Although this book does not pretend to be a history of Gregorian Chant, it does provide an up-to-date, differentiated frame of reference.

IV. Section Four: Text and Rhythm of Gregorian Chant

This section begins with a second statement on the ‘essence’ of Chant:

“Gregorian chant is, essentially, a text in the Latin language, inextricably linked to a melody. From that text, which is primarily a prayer, the composer draws inspiration for the melody, submitting that melody to the rhythm of the word.”

Note on Gregorian Semiology • In “An Initiation” Monsignor Turco does not offer a chapter on Gregorian Semiology. There is an introduction to the Manuscript sources, in which the basics of musical notation in “neumes” are explained, but the application of this knowledge to an interpretation of a specific chant is not offered. One explanation for this choice of Monsignor Turco can be found in an earlier book of his, where we read:

The Gregorian composers spoke Latin: they knew the meaning of the words and their grammatical, logical, and stylistic functions. Above all, they knew the rhythm of the text, its rhythmic unity, and its rhythmic equilibrium. For them, verbal style constitutes the foundational layer of the musical composition. Today, this knowledge and practice of Latin—essential presuppositions for a correct interpretation and performance of Gregorian chant—are not at all familiar. Filling in this gap, at least in part, before undertaking the specific study of paleographic Gregorian notation [semiology]…is obvious.1 Semiology is at the service of the text. If the word, if the phrase, do not flow from the process of accentuation…every semiological detail added to this absence of linear direction will inevitably bear false results.” 2

In place of a presentation of Gregorian Semiology Monsignor Turco offers that which he maintains should precede the study of Semiology. This very substantial chapter is Interpretation in Verbal Style. Essentially, the chapter is a proposal of criteria for chant performance practice.

Chapter Four presents fifteen (15) pages of “examples of textual, melodic-modal and rhythmic analysis.” Each example, is meticulously clear, and logical. Having said that, I hasten to add that working through each example, striving to assimilate all the parameters and elements of “verbal style” in the singing of each example, is a challenging exercise in music analysis and more importantly, exercise of ear-training. This will be true even for experienced, trained musicians. The examples consist of a cantillation of a reading, a proclamation of a psalm tone, and a selection of eight Office antiphons in both syllabic and semi-ornate genres. The analyses presented here can serve as models for students to practice with other antiphons of the repertory and for schola directors to apply to score preparation. The structure of the Liturgy, the Mass and of the Divine Office presents the up-to-date forms of square notation.

More Chapters:

There are many other important and useful topics presented here by Monsignor Turco which I will only name, leaving for you the experience of discovering them.

Section Five, on The Octoechos, presents the Gregorian Modal System, including the “Archaic Modes”, which appear in the newest books of chant prepared by Solesmes. Monsignor Turco, with his Maestro, Dom Jean Claire, O.S.B. are largely responsible for the research which allowed the recovery of these more ancient modes, bringing them back to be sung in today’s Liturgical prayer.

Section Six presents a pedagogy of the practice of Psalmody with explanations of the formula of each Psalm Tone, and how to apply them to texts of the psalms.

The Tones presented are the following:

Psalm tones of the Octoechos (Modes I-VIII and Tonus Peregrinus)

Pre-Octoechos Psalmtones

  • Psalmtone C
  • Psalmtone D
  • Psalmtone E
  • Psalmtone II*
  • Psalmtone IV*

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simple click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

    ‘German’ Introductions for Hymns
    German organ books have an enchanting habit of including introductions for each and every hymn. For example, consider this snazzy example found in a German hymnal published in 1902. In the Saint Jean de Brébeuf Hymnal, that melody is called “Laudes Mariae” and was married to Omni Die Dic Mariae, with a popular English translation (“Daily, daily, sing to Mary”) by Father Henry Bittleston, an Oratorian priest. Notice they also added a ‘tailpiece’ or ‘playout’ or postlude at the end—a very German thing to do!

Quick Thoughts

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

    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.
