Mandatory Advent Piece

Last Sunday, our volunteer choir sang “the mandatory piece” for ADVENT in these United States. Anyone interested can listen to the ‘live’ recording. The claim is sometimes made (erroneously) that this piece can be sung only during the final days of ADVENT. Such an assertion demonstrates a misunderstanding of where this piece came from and […]

“Silent Night” • Easy Organ Arrangement

Here’s a handy organ accompaniment (PDF) in three different key signatures: MIDDLE, HIGH, and LOW. The Latin lyrics (“Silens Nox”) are courtesy of Father Valentine Young, OFM (d. 2020). The organ harmonies are very simple, yet beautiful. Those who desire such a thing may also download a Singer’s Version. Choirs will ‘pick up’ this piece […]

Do You Recognize This Melody?

This morning, I attempted to record a hymn called BRISTOL. Click here to listen to what I produced. I’m trying to provide PIPE ORGAN RECORDINGS for any Brébeuf hymns which don’t (yet) have a choral recording. Thousands of rehearsal videos have been added—by real human voices—but there’s still more work to do. I know very […]

“PPG” • Plainsong Progress by Girls

You can listen to this ‘live’ recording of females singing the INTROIT (“Pópulus Sýon”) last Sunday, which was the Second Sunday of Advent. I accompanied them softly on the pipe organ. I would like to remind everyone who listens: 100% of the singers in my choir are volunteers recruited from the congregation. Indeed, the two […]

Schola Director Posts ‘Live’ Recording

As I explained in my article posted earlier today, Nun Komm Der Heiden Heiland is actually a Catholic tune (in spite of what some have claimed). The volunteer choir I direct sang that beautiful ADVENT melody last Sunday, and I invite you to listen to the live recording. It will get better the more we […]

Message from the Vice-President!

The Vice-President of the Church Music Association of America, Dr. Horst Buchholz (who also serves as Director of Sacred Music for the Archdiocese of Detroit) sent us an email yesterday regarding the harmonizations (PDF) I composed for the Gregorian Chant psalm tones. Dr. Buchholz says: “Those settings are absolutely exquisite, as I’m used to when […]

My Response to Dr. Weaver’s Latest Article

Is it fair to forever bind Dom Guéranger to what he wrote about “barbarous archaisms” in 1855?

Requesting Our Advent Eucharistic Hymn

A young lady named Agnes wrote to us: “Dear Mr. Ostrowski, do you have the PDF score for Ave Corpus Domini set to the ADVENT melody? Last year, we sang the hymn tune “Nun Komm der Heiden Heiland” quite a bit using your contrafactum technique. My choir appreciates the Latin hymns and practice videos, especially […]

    Oldest Latin Eucharistic Hymn
    The Church’s oldest Latin Eucharistic hymn is featured in the Brébeuf Hymnal. Indeed, the legendary Father Adrian Fortescue made a translation of it—matching the original’s meter—which was elevated by the Brébeuf team. For years, we’ve been working on a Spanish hymnal: “Cantoral del Padre Antonio Daniel.” The progress has been slow but steady, and we encourage anyone fluent in Spanish to consider joining the proofreading team. A few days ago, my wife helped me record a rehearsal video for this Spanish version of the Church’s oldest Latin Eucharistic hymn.

    Rare Plainsong Accompaniments
    Our contributor, Veronica Brandt, went deep into Australia to take photographs of organ accompaniments for Gregorian Chant. Some consider these peculiar PLAINSONG ACCOMPANIMENTS—with 3-part harmonies by Barcelona Cathedral organist, Father Josep Muset i Ferrer—to be the rarest in the world. Click here to learn more. Thanks Veronica! 😊

Quick Thoughts

    “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). 😊

    Time and Again We Are Asked…
    John Baptist Singenberger (d. 1924) was a central figure of Catholic Church music. In this utterly fascinating excerpt (Single-Page PDF), Singenberger writes: Time and again we are asked: “Is the Gregorian chant to be accompanied by the organ?” As a young student in Saint Gall, Singenberger befriended SEBASTIAN GEBHARD MESSMER, the future Archbishop of Milwaukee (Wisconsin). The two graduated together in 1861. The school they attended (Saint George’s Seminary) was a “seminary”—but in the older European sense. In other words, it provided a classical education without necessarily leading to ordination. Singenberger remained a layman his whole life, but Messmer was eventually made archbishop—by Pope Saint Pius X—of the very archdiocese in Wisconsin where Singenberger would spend his American career, giving him a powerful ecclesiastical ally.

Random Quote

The representative Protestant collection, entitled “Hymns, Ancient and Modern”—in substance a compromise between the various sections of conflicting religious thought in the Establishment—is a typical instance. That collection is indebted to Catholic writers for a large fractional part of its contents. If the hymns be estimated which are taken from Catholic sources, directly or imitatively, the greater and more valuable part of its contents owes its origin to the Church.

— Orby Shipley (1884)
