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.”

10 Examples • “Diversity of Musical Styles” at the Traditional Latin Mass

Jeff Ostrowski · April 14, 2021

NOW THIS: it’s impossible to succeed as a church musician if one must constantly “justify one’s existence.” That is to say, the vocation of a choirmaster is already extremely difficult (physically and mentally). On top of all that, if one must constantly persuade one’s boss of one’s value, that’s too much—at least, in my humble opinion. Years ago, I worked for a priest whom I had to “entertain.” He demanded different songs at all five Masses each weekend—and if he wasn’t sufficiently entertained, the musician paid a heavy price. It was terrible! Therefore, one must find a priest who already understands the Catholic Mass demands a certain type of music that isn’t up for debate. One must find a priest who already knows that the Holy Mass is not about entertainment; it’s about glorifying God. At the same time, the music should be sung well. It must be beautiful and fitting. It should be a source of delight to anyone who hears it. In 2013, I spoke about the need for a diversity of styles during the Holy Mass. Some pieces should be organ only. Others, organ with voices. Some, voices only. Some Renaissance. Some Baroque. Some Gregorian Chant. Some Modern. And so forth and so on. I still believe this to be quite important.

Diverse Music For Mass

My colleague, Keven Smith, recently spoke of rebooting your choir, post-Covid. I have already described the difficult situation here in California due to Covid-19. We are not allowed to have choir rehearsals, which has caused me great anguish. In spite of this, I hope you will allow me to share some audio examples from last Sunday’s Mass—even though we aren’t allowed to have rehearsals—to illustrate ten ways you can obtain diversity:

(1) Modern Music

We like to sing modern music. Here’s an excerpt from Sunday, composed in 2013 by Richard Rice:

*  Mp3 Excerpt • MODERN MUSIC
—Recorded live at the FSSP Mass in Los Angeles.

(2) Common Practice Era • Unison

We like to sing hymns in unison. Here’s #785 from the Brébeuf hymnal, recorded live:

*  Mp3 Excerpt • UNISON HYMN
—Recorded live at the FSSP Mass in Los Angeles.

(3) Common Practice Era • Trebles

We like to hear just the Alto and Soprano sections. Here is #258 from the Brébeuf hymnal, a tune called “La Rochelle” with the text of Jesu Nostra Redemptio (“Redeemer of our fallen state”):

*  Mp3 Excerpt • SOPRANO + ALTO
—Recorded live at the FSSP Mass in Los Angeles.

(4) Common Practice Era • Mixed

It is possible to sing hymns with Tenor, Alto, and Soprano. Here is #434 from the Brébeuf hymnal. It’s a tune called “Notre Dame” with the ancient text of Rex Sempiterne Domine (“Eternal King of Heaven’s hosts”):

*  Mp3 Excerpt • TENOR + TREBLES
—Recorded live at the FSSP Mass in Los Angeles.

(5) Mediæval Harmonies

We like to sing Mediæval polyphony, and we did that for the AGNUS DEI:

*  Mp3 Excerpt • MEDIEVAL MUSIC
—Recorded live at the FSSP Mass in Los Angeles.

(6) A Cappella Plainsong

Of course, there was plenty of plainsong without organ. Here is Post Dies Octo Januis Clausis (what Father Lasance calls the “Greater Alleluia”):

*  Mp3 Excerpt • PLAINSONG WITHOUT ORGAN
—Recorded live at the FSSP Mass in Los Angeles.

(7) Accompanied Plainsong

And there was plenty of accompanied plainsong, as well. Here’s the Vidi Aquam sung by the ladies:

*  Mp3 Excerpt • PLAINSONG WITH ORGAN
—Recorded live at the FSSP Mass in Los Angeles.

(9) Harmonized Plainsong

We even sing “harmonized” chant—as I spoke about in a recent blog post:

*  Mp3 Excerpt • HARMONIZED CHANT
—Recorded live at the FSSP Mass in Los Angeles.

(10) Chant With Drone

To evoke a more “peaceful” feeling, we had the men sing a “ison” for Gloria IX:

*  Mp3 Excerpt • Gloria IX with Drone
—Recorded live at the FSSP Mass in Los Angeles.

In addition to every combination you could imagine (soloists, female only, men only, men and female, and so forth), we also had—needless to say—organ music of every genre: French, Baroque, Modern, and so forth.

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    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. Simply 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.

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

“Much of the reordering [in 1970] of the pieces of the Roman Gradual seems arbitrary and useless; nevertheless, with some exceptions, it does not affect the shape of the service, since like pieces are exchanged for like.”

— Dr. William Peter Mahrt
