An Interview with Bruno de Labriolle

Readers interested in different stylistic approaches to Gregorian chant may enjoy this interview with the singer Bruno de Labriolle, who directs the schola of Saint-Bruno-des-Chartreux in Lyon. The views on chant and liturgy aired in the interview aren’t exactly the same as those of any of our contributors, but I personally find this group’s performances, in […]

More Than A Chart!

I’ve received many compliments about a comparison chart which was part of a recent article I posted. I feel flattered by these kind words, but I would like to point out that my chart doesn’t make much sense unless one reads the entire article.

“Counter-Melody” for a Hymn Tune…

Jeff Ostrowski has added a “counter-melody” to CUPERTINO, a hymn tune composed by Kevin Allen. You can download the Organist Score (PDF), which doubles as the vocalist score. You can also hear Jeff’s volunteer choir sing that “counter-melody” version in real life by clicking here.

Easter Sequence • “Both English and Latin”

Earlier this afternoon, I created an organ harmonization for the EASTER SUNDAY SEQUENCE: Víctimæ Pascháli Laudes in English and Latin. The rhythm conforms to the pure (“untouched”) Vatican Edition, like what you’d find in editions by Schwann, Monsignor Nekes, Max Springer of Beuron, and Peter Wagner (Commissionis Pontificiæ Gregorianæ Membrum). The beautiful and highly accurate […]

Theological…

The 330-page booklet for Sacred Music Symposium contains more than just fabulous and inspiring music. Little theological ‘tidbits’ cover its pages. For example, consider Page 265. You can download a PDF copy of the entire booklet at the Symposium website.

PDF • “For General Use Until Advent”

If you conduct a volunteer choir, you might consider using this Simple Piece #40273 (“Adésto Sáncta Trínitas”) which can be used during the rest of the liturgical season until Advent. It’s based on the well known hymn tune: OLD HUNDREDTH. Rehearsal videos are available at #40691. A live recording of #40273 (“Adésto Sáncta Trínitas”) by […]

Introit • (This Coming Sunday)

Our volunteer choir appreciates training videos, so here’s my attempt at recording “Exáudi Dómine Vocem Meam,” which is the INTROIT for this coming Sunday. This coming Sunday is Dominica Post Ascensionem (“Sunday after the feast of the Ascension”). It is sung according to the official rhythm of the Catholic Church.

Volunteer Choir Attempts “Kýrie Eléison”

My volunteer choir attempted the polyphonic KYRIE that will be sung at this year’s Sacred Music Symposium. If you’re interested, you can listen to the live recording from last Sunday. The piece is based on the ancient plainchant hymn melody: Ave Maris Stella. Polyphony like this is truly intricate and wonderful. It reminds me of […]

Vespers Accompaniment Booklet

A VESPERS ACCOMPANIMENT BOOKLET (20 pages) for this coming Sunday—the 5th Sunday after Easter—can now be downloaded. Those who sing Vespers exactly as given in the ANTIPHONALE ROMANUM will notice that all five psalms for Eastertide are sung according to the exact same tone with the exact same differentiæ. Can someone explain why this is? […]

Examples of comments we recently received, from all over the globe:   (1) “The Byrd composition your student sung was certainly beautiful.

FEEDBACK • 26 April 2023

A reader wrote to us about the MELCOMBE HYMN ARTICLE (whose official title was: 1950s Catholicism: Do We Want It Back?) with these kind words: “I so wish there was a CD of your choir. The Introit the other day stays with me all day!”

    Proportionalist Plainchant • (Documented)
    On this website, we believe: “If we don’t know where we came from, we can’t know where we’re going.” As a result, we often spend hours scanning old books of GREGORIAN CHANT (and organ accompaniments). We don’t claim those items are useful or desirable for today’s circumstances; the goal is understanding where we came from. Here is a fascinating musical score from the 19th century. At that time, it was believed that MENSURALISM (a.k.a. “proportionalism”) was the historically correct way to sing plainsong.

    Absolutely ‘Perfect’ Voice-Leading?

Quick Thoughts

    “Predictable Rhymes?” • A Follow Up
    We received considerable correspondence regarding my article, Two Ways to Defile a Hymn. More specifically, what really raised certain people’s hackles was its follow-up article dealing with the keyboard accompaniment for the CHRIST THE KING HYMNAL. But to quote Eliza Doolittle: “Have I said anything I oughtn’t?” Please examine this PDF file and see whether you agree. Were the editors of the BRÉBEUF HYMNAL incorrect to insist upon sophisticated and clever rhymes, rather than mind-numbingly predictable rhymes?
    —Jeff Ostrowski
    ‘Ould’ But Not Good
    Dom Samuel Gregory Ould (note the spelling) was a Benedictine monk at FORT AUGUSTUS ABBEY in Scotland. As musician, organist, and composer, Dom Ould was highly regarded. Moreover, he was considered an authority on Gregorian Chant. But not everything found in an old book—or, in this case, an “Ould” book—is necessarily praiseworthy. Consider this page from Dom Ould’s hymnal. Do you see the rhymes? They offend severely by ABR (“Abuse By Reuse”) and are utterly predictable. In my recent article—Two Ways to Defile a Hymn—I addressed this topic.
    —Jeff Ostrowski
    “Reader Feedback” • 22 June 2026
    A reader wrote to us from Virginia: “I really appreciate the 23 harmonizations that you posted on CORPUS CHRISTI WATERSHED for the Daily, Daily, Sing to Mary hymn. I hope to find willing voices in our small Schola Cantorum to try the three-voice version. Carry on, sir! You’re doing the Lord’s work.” While we don’t know this gentleman personally, we note that he earned a Ph.D. (which demonstrates that our blog has something for everybody). 😊

Random Quote

In 1951 (and again in 1952 and 1955) the Sacred Congregation of Rites gave permission to the bishops of the whole world to celebrate the “Vigil of the Lord’s Resurrection” as much as possible in conformity with the ancient ceremonial: the most noticeable change was to transfer the ceremonies to the late evening of Holy Saturday. During the experimental period the text of the Missal remains unchanged, and a special “Ordo Sancti Sabbati” has been published.

— Charles Richard Anthony Cunliffe (1955)
