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 · May 29, 2021

EENLY AWARE. I am keenly aware of my flaws as a choirmaster. One of them is my reluctance to “take risks” with my singers, especially when it comes to high or low tessitura. In an effort to counteract this tendency, we are doing an experiment with the (all female) TREBLE CHOIR I direct. Specifically, we are doing something Dr. Horst Buchholz often does at the Cathedral Basilica of St. Louis: adding a polyphonic section to Credo VII at the words “Et Incarnatus Est.”

Readers already know that musical diversity at Mass is something we believe to be essential; and we harp on this subject often—if you’ll pardon the pun! It would seem that Papal Masses in the time of Giovanni Maria Nanino (d. 1607) show diversity as well. At the bottom of this article, I have included a quote which talks about 16th century Papal Masses, and you’ll notice they utilize different performing forces for specific parts of the Mass, such as a TREBLE CHOIR for the “Kyrie” on Ferial days. Here’s the “polyphonic extension” we are attempting with my TREBLE CHOIR (all female):

—In 1571, Nanino replaced Palestrina as Maestro di cappella at the Basilica of St. Mary Major.

Sometimes the rehearsal videos are a tad fast, but in real life we slow things down to an appropriate tempo based on the acoustic.

The Full Quote: Below is the full quotation vis-à-vis Nanino, courtesy of Monsignor Richard J. Schuler:

Nanino in his “Diario” furnishes us with a complete picture of the year’s activity of a papal singer. He lists the feasts on which—in addition to all Sundays—no singer could be excused from his obligation. Thus he has left us a record of the feast days celebrated by the papal household with special solemnity at the end of the sixteenth century. […] Nanino indicates to some extent the kind of music employed depending on the liturgical rank of the day being celebrated. For example, he specifies that on ferial days (week days without a special feast) the office of Matins and all the hours are only read. The “Introit” of the Mass is sung in plain chant (canto fermo), and the gradual and the tract are sung by the choir of canons (a choro). The “Kyrie” is to be sung by the treble voices (voce alta) and the “Offertory” is performed in counterpoint. He directs that the “Sanctus” be done in parts (in musica) and the “Communion Anthem” in chant, alternating with the treble voices (meditante in voce alta). Vespers are done in chant, except for the antiphon to the “Magnificat” which is sung in counterpoint. A more elaborate arrangement is indicated for feast days. […] Nanino takes considerable pains to establish his system of keeping the records of disciplinary infractions, since that was his obligation as punctator. He seems to say that he is giving fair warning to all of how he will proceed. It almost points to the existence of complaints against his attitude, rather than just a forestalling of future arguments over his system. First, he takes up the question of absences, noting that each singer could miss two days in a year’s time, provided those days were not Sundays, feasts of the Blessed Virgin, the Apostles or Evangelists, or any day listed in the calendar at the beginning of his “Diario.” Neither could anyone miss a public consistory held in the Sala Ducale of the Vatican palace. He solves the problem of the distinction between absences and tardiness by declaring that a singer who is not in his place by the end of the Epistle will be marked absent. Fines vary according to the rank of the day on which the tardiness or absence occurred, and if any bonus (regaglia) should come to the singers because of an appearance of the choir at a function outside the Sistine chapel, the culprit would forfeit his share. At papal Masses, the regulations against tardiness were more stringent than at Masses celebrated by cardinals or bishops. Nanino records that any singer who is “not in his place and in his vestments” by the end of the repetition of the “Introit” will be fined eight vinti. At papal Vespers, the singer who is not present at the “Gloria Patri” of the first psalm pays a fine of fifty balocchi.

    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 Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    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!

Random Quote

“…it would be a very praiseworthy thing and the correction would be so easy to make that one could accommodate the chant by gradual changes; and through this it would not lose its original form, since it is only through the binding together of many notes put under short syllables that they become long without any good purpose when it would be sufficient to give one note only.”

— Zarlino (1558) anticipating the Medicæa
