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.”

We love getting messages like this one…

“I am a 25-year-old organist and cantor from the mountains of Northern Colorado. I wanted to take this opportunity to thank you and your friends for working hard to bring excellent content to your website and my inbox. I have found many, many awesome resources to help me stay faithful to the Church’s stance and […]

What is the “Ordinary” of the Mass?

A few years ago—during the Sacred Music Symposium—I suggested to the audience that the “Our Father” and the “Alleluia” should be considered part of the Ordinary of the Mass (for the Ordinary Form). In my own settings, such as Mass of the English Martyrs, I treated the “Our Father” accordingly—and here in Los Angeles, we […]

Being Too Hard On Priests?

I’m usually a stickler when it comes to making sure priests sing their chants correctly, especially when priests often substitute a Perfect Fourth for the Minor Third in the famous Triple Alleluia on Holy Saturday. But I just found out the 1575AD Missale Romanum has a skip of a Perfect Fifth! So perhaps I need to […]

Dealing With Calumny

All of us have probably been the victim of calumny. Calumny can be especially painful if the person telling lies is someone you helped. Next time this happens in your life, try an experiment: Write the person’s name on an Index card, place it on your shoulder, and flick it to the ground—meaning you will […]

From “Vexilla Christus Inclyta”

Non ille regna cládibus, | Non vi metúque súbdidit: | Alto levátus stípite, | Amóre traxit ómnia.—“It is not by combat or force or fear that Christ subdues nations but lifted up upon the tree, he draws all things to himself by love.” Servat fides connúbia, | Juvénta pubet íntegra, | Pudíca florent límina | […]

“Daily I sat in the temple, close to you…”

Fulton J. Sheen always said the “very best translation” of Sacred Scripture was the version by Monsignor Ronald Knox, and here’s what Knox had for the Passion read today (Pre-1955 Palm Sunday): “And Jesus said to the multitude at that hour, You have come out to my arrest with swords and clubs, as if I […]

Sacred Music Symposium • “What We Avoid”

I wish we had to time to discuss artwork at the Sacred Music Symposium, but there’s just not enough time. At this year’s conference in June, we will sing an absolutely incredible Magnificat setting by Father Francisco Guerrero (d. 1599). If you examine the part books, you will notice a marvelous aesthetic desire to avoid […]

“Abraham” • Guerrero Imitates His Teacher

Father Francisco Guerrero (d. 1599) studied music with Father Cristóbal de Morales circa 1545. He taught himself the organ. On 3 April 1542 he was engaged as a contralto by Seville Cathedral at an annual salary of 12,000 maravedís. He remained there until 1546, when, at the age of only 17, he was invited—on the […]

Too much music!

Choosing music for the Sacred Music Symposium requires careful consideration.  We make sure (always) to have great variety. Because the schedule is so full, there’s never sufficient time to discuss the music fully—indeed, we could easily do a month-long seminar on each piece!  For example, last year Dr. Calabrese conducted a setting of the Magnificat […]

“Sharing Is Caring”

I would like to share a message from a highly respected scholar.  (His articles appear in distinguished journals such as Études grégoriennes and Oxford’s Early Music.) He wrote as follows: The Brébeuf Hymnal is very tastefully done. Your team has exquisite literary and musical taste. I see from my copy of the hymnal that you […]

What Frightens Me

The world’s experts have been releasing contradictory statements Re: Covid-19. I am neither a doctor nor a scientist, so I won’t comment; but I have something to say about the spine-tingling predictions made by certain politicians. When I was growing up, they told us “within ten years” we would starve due to overpopulation. The next […]

Official Statement on Coronavirus

The 2020 Sacred Music Symposium “Official Statement” on Coronavirus has been posted; I encourage everyone to read it. I would like to share some advice: (1) avoid excessive amounts of “cable news” reporting on the pandemic, similar to how we diligently avoid immoral magazines and pornography; (2) let us pray for God’s mercy, and let […]

The Ability To Say “I Don’t Know”

Father Valentine Young, OFM, always spoke about people incapable of saying “I don’t know.”  Such people have an answer for everything—as if saying “I don’t know” would cause them physical pain.  That’s how I acted growing up, but I stopped when I reached maturity.  Another thing I did as a kid was insist that I […]

Disturbing Trend

Have you noticed how many people these days don’t know what an analogy is?  If I say to John Doe, “that’s the pot calling the kettle black,” frequently John Doe will go around telling everybody I called him an ugly pot.  It’s quite disturbing.  I’ve also noticed that many Americans believe the definition of “possible” […]

Internet Bullies

Any Christian who tries to make a difference in the sacred music world must expect to face opposition and scorn. Today, the attacks will frequently come from “internet cowards” who hide behind false names, fake biographies, anonymous blogs, and so forth. Falsehoods and calumnies from anonymous sources are impossible to debunk—because recognition is what they […]

    Music List • “5th Sunday of Easter” (Year A)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for the 5th Sunday of Easter Sunday—a.k.a. “Dominica V Paschae”—which is 3 May 2026. Please feel free to download it as a PDF file if such a thing interests you. The COMMUNION (“Tanto Témpore Vobíscum Sum”) is rather somber, with awesome fauxbourdon psalm verses. The ENTRANCE CHANT is bright and happy.
    —Jeff Ostrowski
    PDF Download • Communion for Sunday
    The COMMUNION ANTIPHON with fauxbourdon psalm verses for this coming Sunday (3 May 2026) is elegant and poignant. It’s such a shame it only comes every three years. This piece—along with all the musical scores for this coming Sunday, which is the 5th Sunday of Easter (Year A)—can be downloaded free of charge from the flourishing feasts website. By the way, how is it already 2026?
    —Jeff Ostrowski
    Season’s End Repertoire
    Looking at the REPERTOIRE SHEET until the end of the choral season, I see that I’ve fallen behind schedule. (The last three months have been extraordinarily busy.) As you know, I have been providing organ harmonies for all the ENTRANCE CHANTS—as well as rehearsal videos—and you can see I’m behind where I planned to be. Now I must make up lost ground. However, the choir picks up the ENTRANCE CHANT with ease, so I’m sure it will all work out. My ‘unofficial’ harmonizations are being posted each week 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.
    —Jeff Ostrowski
    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!
    —Jeff Ostrowski

Random Quote

“The tradition of Roman documents establishes a clear hierarchy. Gregorian chant has pride of place; classical polyphony has a privileged role. It is because styles carry with them associations and even evoke a place—the style of a Broadway show tune evokes the theater; the style of cocktail music evokes the cocktail bar, yet we hear these styles in church. The priority of sacred styles needs re-emphasis.”

— Dr. William Peter Mahrt
