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.”

16 May 2022 • Harmonized Chant?

This year’s upcoming Sacred Music Symposium will demonstrate several ways to sing the CREDO at Mass. This is because—for many parishes—to sing a full-length polyphonic CREDO by Victoria or Palestrina is out of the question. Therefore, we show options that are halfway between plainsong and polyphony. You can hear my choir rehearsing a section that […]

Worst Chanting I’ve Ever Heard

The Supreme Court has been in the news lately.

14 May 2022 • “Pure” Vatican Edition

As readers know, my choir has been singing from the “pure” Editio Vaticana. That is to say, the official rhythm which—technically—is the only rhythm allowed by the Church. I haven’t figured out how I want the scores to look, so in the meantime we’ve been using temporary scores that look like this. Stay tuned!

14 May 2022 • Gorgeous Book

If there is a more beautiful book than Abbat Pothier’s 1888 Processionale Monasticum, I don’t know what it might be. This gorgeous tome was today added to the Saint John Lalande Online Library. I wish I owned a physical copy.

“Yes or No?” • Thoughts On Singing The Creed

If his choir sounds terrible, why would you trust his advice?

Sound Familiar?

1 June 1579: “The chapter passes a rule that anyone ascending to the new organ without official permission shall be fined a month’s pay.” 26 October 1579: “The altar boys remain always separate and distinct from choirboys—the one group learning only plainchant and assisting at the altar, the other living with the chapel-master and studying […]

A “Dirty” Word (For Musicians)

Around the year 1955, “transcription” became a dirty word.

Choirs Love This Piece!

Back in 2001, I created an arrangement of “O Filii Et Filiae” based on the work of Monsignor Jules Van Nuffel. You can access free rehearsal videos at #5909. Choirs absolutely love singing this piece. You can hear my volunteer choir singing a live recording.

Holy Thursday Introit • “Pure” Vaticana

Many people wonder what Cantus Gregorianus sounds like when sung according to the “official rhythm.” You can hear the Introit for Maundy Thursday sung that way—i.e. according to the “pure” Editio Vaticana—if you click here. Technically, this is the only interpretation allowed by the Church; cf. the letter of Cardinal Martinelli (18 February 1910).

Kevin Allen’s “Dómine Convértere” Sung At Saint Peter’s Basilica (Vatican City)

The Vatican’s choir sounds beautiful these days—no longer is it “the scandal of Christendom.”

“Ah, Holy Jesus, How Hast Thou Offended?”

A wonderful passiontide hymn is #692 in the Brébeuf hymnal. It works especially well for Communion. Here is a live recording from last Sunday, sung by the fabulous female singers in my volunteer parish choir.

President’s Corner

    Music List • (3rd Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday: the 3rd Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.
    —Jeff Ostrowski
    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

Quick Thoughts

    “Reminder” — Month of January (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. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.
    —Jeff Ostrowski
    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.
    —Jeff Ostrowski

Random Quote

“The council did not say Latin should be abolished. It said Latin should be used. […] While at Ecclesia Dei, I once received a letter from a chancery office in the United States, asking me if I didn’t know that the council had abolished Latin!”

— Cardinal Mayer, Prefect (1985–1988) of the Vatican’s Congregation for Divine Worship
