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 […]

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.

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 […]

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).

“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.

PDF Download • “Palm Sunday Hymn”

During the procession on Palm Sunday, the 1962 rubrics allow alius cantus in honorem Christi Regis—“a hymn or song in honor of Christ the King.” A simple yet beautiful Gregorian hymn you might consider is Te Sæculorum Principem, which was composed for the feast of Christ the King by Father Vittorio Genovesi (d. 1967). The […]

Free Organ Accompaniment • “Vexilla Regis”

During Passiontide, the hymn at Vespers is the mighty Vexilla Regis Prodeunt of Bishop Venantius Fortunatus. In 2015, I composed an organ accompaniment for this hymn with each verse written out. This comes in pretty handy on occasions when the organist must “lead the hymn from the organ bench.” Please feel free to download my […]

Surprise! • Bas PDF from Paris

A generous person in Paris sent us the 1921 organ accompaniment to the Requiem Mass (“Missa Pro Defunctis”) harmonized by Julius Bas, who was associated with the Abbey of Solesmes. You can download the entire PDF file for free at the Lalande Library. I must say, what Bas does with Dies Irae sequence is fascinatingly […]

Marvelous News From Pope Francis!

Two members of the Priestly Fraternity of Saint Peter recently met with Pope Francis at the Vatican. (You can read the whole story.) The Pope insisted that the FSSP should be “preserved, protected, and encouraged.” Moreover, Pope Francis made it clear that institutes such as the Fraternity of Saint Peter are not affected by the […]

PDF Download • Quinquagesima Vespers

I created a booklet for my choir. (The congregation already has their own booklet). This booklet is for Quinquagesima Vespers, and you can download it if you desire. Print on “double sided” and the booklet will come out correctly. The polyphonic Magnificat is not included in that booklet, since the choir members have it in […]

FEEDBACK • 25 February 2022

We love receiving mail from our readers. Here are two messages we received today from two different music directors in Canada: (1) “We are a small Schola in Yukon, Canada and love your practice videos repertoire.” (2) “Thank you so much for the indispensable work that you are doing to rebuild the musical life of […]

A Fugue that “explains” itself

One of my choir members sent me this Ontological Fugue. If you can get past the performance—which is terrible (perhaps on purpose)—you will learn an awful lot about fugues. In my opinion, whoever created that score is a genius! It would be awesome to know from a professional theorist, such as Charles Weaver, whether they […]

President’s Corner

    “Offertory” at Catholic Funerals
    I have argued that the OFFERTORY—at least in its ancient form—is more of a responsory than an antiphon. The 1962 Missal specifically calls it “Antiphona ad Offertorium.” From now on, I plan to use this beautiful setting (PDF) at funerals, since it cleverly inserts themes from the absolution of the body. Tons more research needs to be done on the OFFERTORY, which often is a ‘patchwork’ stitching together various beginnings and endings of biblical verses. For instance, if you examine the ancient verses for Dómine, vivífica me (30th Sunday in Ordinary Time) you’ll discover this being done in a most perplexing way. Rebecca Maloy published a very expensive book on the OFFERTORY, but it was a disappointment. Indeed, I can’t think of a single valuable insight contained in her book. What a missed opportunity!
    —Jeff Ostrowski
    “In Paradisum” • Gregorian Chant
    As a RECESSIONAL on All Souls’ Day (November 2nd), we will sing In Paradísum Dedúcant Te Ángeli (PDF). When it comes to Gregorian Chant, this is one of the most popular “songs.” Frankly, all the prayers and chants from the traditional REQUIEM MASS (Missa exsequialis or Missa pro defunctis) are incredibly powerful and never should’ve been scuttled. Click here to hear “In Paradisum” in a recording I made this afternoon. Professor Louis Bouyer spoke of the way Bugnini “scuttled the office of the dead” in this fascinating excerpt from his memoirs. In his book, La riforma litugica (1983), Bugnini bragged—in quite a shameful way—about eliminating the ancient funeral texts, and even admitted those venerable texts were “beloved” (his word) by Catholics.

    “Music List” • All Souls (2 November)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 2 November 2025, which is the Commemoration of All the Faithful Departed (“All Souls”). 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 conveniently stored at the top-notch feasts website alongside the official texts in Latin. In my humble opinion, it’s weird to have the feast of All Saints on a Sunday. No wonder the close associate of Pope Saint Paul VI said the revised KALENDAR was “the handiwork of a trio of maniacs.” However, I can’t deny that sometimes the sacred liturgy consists of elements that are seemingly contradictory: e.g. the Mode 7 “De Profúndis” ALLELUIA, or the Mode 8 “Dulce lignum” ALLELUIA on the various ancient feasts of the Holy Cross (3 May, 14 September, and so on).

Quick Thoughts

    Gospel Options for 2 November (“All Souls”)
    We’ve been told some bishops are suppressing the TLM because of “unity.” But is unity truly found in the MISSALE RECENS? For instance, on All Souls (2 November), any of these Gospel readings may be chosen, for any reason (or for no reason at all). The same is true of the Propria Missæ and other readings—there are countless options in the ORDINARY FORM. In other words, no matter which OF parish you attend on 2 November, you’ll almost certainly hear different propers and readings, to say nothing of different ‘styles’ of music. Where is the “unity” in all this? Indeed, the Second Vatican Council solemnly declared: “Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community.”

    “Our Father” • Musical Setting?
    Looking through a Roman Catholic Hymnal published in 1859 by Father Guido Maria Dreves (d. 1909), I stumbled upon this very beautiful tune (PDF file). I feel it would be absolutely perfect to set the “Our Father” in German to music. Thoughts?

    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.

Random Quote

“I am now old but I was young when I was received into the Church. I was not at all attracted by the splendour of her great ceremonies—which the Protestants could well counterfeit. Of the extraneous attractions of the Church which most drew me was the spectacle of the priest and his server at Low Mass, stumping up to the altar without a glance to discover how many or how few he had in his congregation; a craftsman and his apprentice; a man with a job which he alone was qualified to do.”

— Evelyn Waugh (7 August 1964)
