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.”

PDF • “Propers in figured notation”

Jennifer Urquhart wrote to us: “I’m currently involved in providing music for a non-specialist choir which will sing a TLM for the Sacred Heart. Since those propers changed in 1929, the one in the figured Liber Usualis (1924) now has the wrong texts.” Jennifer placed those propers into modern notation, which you can download as […]

“Hail Redeemer, King Divine”

Click here to listen to our 100% volunteer choir singing this famous hymn without organ. By way of comparison, you can hear the same choir sing that hymn accompanied by the pipe organ if you click here. Both have advantages and disadvantages. Please feel free to email me and tell me which you like better.

Organ Accomp. • “Ascension Hymn at Vespers”

The soul-stirring hymn used on ASCENSION THURSDAY at Vespers—and also used on the Sunday which follows the Ascension—was called in the 7th century: “Jesu Nostra Redemptio.” After 1631AD, the title of that hymn was changed to “Salutis Humanae Sator.” The melody assigned by the Vatican Commission on Gregorian Chant is rather mournful (and very difficult […]

Hymn for the Ascension

Here is a ‘live’ recording from the Mass on Ascension Thursday (2024): Hymn for the Ascension. I could not be prouder of this parish choir, which consists 100% of volunteers. To learn more about this hymn, please visit #704 in the hymn portal. I have argued that—in addition to CARMEN GREGORIANUM, organ music, and polyphony—hymns […]

“Praise To The Lord” • Simple Accomp.

In case you missed the full article I posted the other day on Views from the Choir Loft, feel free to download a PDF version of my simplified organ accompaniment for the famous hymn “Praise To The Lord,” which is often paired with LOBE DEN HERREN. I’m toying with the idea of creating a whole […]

PDF Download • “Ad Regias” Hymn

Upon hearing this special rendition of the ancient Roman Catholic hymn for Eastertide known as “Ad Régias Agni Dapes” several readers requested the score. You may now download the PDF Score (4 pages) completely free of charge. [Rehearsal videos for each individual part are waiting for you at #33013.] For the record, prior to 1632AD […]

Organ Accompaniment Booklet (20 pages)

This coming Sunday in the Extraordinary Form will be the Fifth Sunday after Easter. Each week, everyone can freely visit this page, downloading such booklets (as it were) directly from the source. Nevertheless, I’d like to draw your attention to the ORGAN ACCOMPANIMENT BOOKLET (20 pages) for Vespers in the Extraordinary Form: Dominica V Post […]

Random Psalm Tone! • (1962 Weddings)

I believe it’s better to sing a Psalm Tone with excellence rather than attempt the authentic CARMEN GREGORIANUM (Gregorian Chant) in a plodding, lifeless, poorly-executed way. To that end, I have created this Fifth Mode Psalm Tone version for the COMMUNION CHANT assigned to 1962 Missal weddings. The Nuptial Mass is sometimes called “Pro Sponso […]

Can Your Choir Members Do This?

How many of your choir members can do this? (a) Recite the Tantum Ergo from memory; (b) Explain where the piece comes from and when specifically—during HOLY WEEK—it’s used; (c) Provide a literal translation (from memory, without looking in a book). This nifty one-page sheet (PDF) might be worth downloading if you’re worried some of […]

“Banish Wrong Notes!” • Hymns Simplified

In the past, I’ve mentioned how I can’t stand hearing wrong notes. I was playing LLANFAIR the other day, and I was hitting wrong notes. Earlier today, I created a simplified version which you can download for free. This famous tune (“LLANFAIR”) is often used on the feast of the Ascension, with “Hail the Day […]

“Jesus Christ is Ris’n Today” (Simplified)

I hate hearing organists play wrong notes. I invite you to download this simplified organ accompaniment for hymn #699 in the Saint Jean de Brébeuf Hymnal. The hymn is “Jesus Christ Is Risen Today.” I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was […]

“Strangest Of All…” • (Fortescue)

In his illustrious 1912 tome—The Mass: A Study Of The Roman Liturgy—Father Adrian Fortescue spoke of sequences, writing: “Strangest of all were the vernacular sequences in France and Germany, or those partly vernacular and partly Latin.” Our volunteer choir experimented with that on Holy Thursday, mixing Latin verses with an English refrain. For the record, […]

William Byrd • “Mass for Five Voices”

Working with volunteers can be discouraging, but always remember there’s light at the end of the tunnel. Yesterday, during PALM SUNDAY MASS, our 100% volunteer choir pulled out the SANCTUS from William Byrd’s “Mass for Five Voices.”  This colossal performance was the result. (They literally didn’t know I was going to have them sing that […]

President’s Corner

    New Bulletin Article • “21 September 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 21 September 2025) discusses some theological items—supported by certain verses in ancient Catholic hymns—and ends by explaining why certain folks become delirious with jealousy when they observe feats by Monsignor Ronald Knox.
    —Jeff Ostrowski
    Cheap! Cheap! Cheap!
    It’s always amusing to see old diocesan newspapers—in huge capital letters—advertising the Cheapest Catholic Paper in the United States. The correspondent who sent this to me added: “I can think of certain composers, published by large companies in our own day, who could truthfully brag about the most tawdry compositions in the world!” I wonder what she could have meant by such a cryptic comment…
    —Jeff Ostrowski
    PDF Download • Dom Murray Harmonies
    Along with so many others, I have deep respect for Dom Gregory Gregory Murray, who produced this clever harmonization (PDF) of “O SANCTISSIMA.” It’s always amazed me that Dom Gregory—a truly inspired composer—was so confused when it came to GREGORIAN CHANT. Throughout his life, he published contradictory statements, veering back-and-forth like a weather vane. Toward the end of his life, he declared: “I see clearly that the need for reform in liturgical music arose, not in the 18th and 19th centuries, but a thousand years earlier—in the 8th and 9th centuries, or even before that. The abuses began, not with Mozart and Haydn, but with those over-enthusiastic medieval musicians who developed the elaborate and flamboyant Gregorian Chant.”
    —Jeff Ostrowski

Quick Thoughts

    Karl Keating • “Canonization Questions”
    We were sent an internet statement (screenshot) that’s garnered significant attention, in which KARL KEATING (founder of Catholic Answers) speaks about whether canonizations are infallible. Mr. Keating seems unaware that canonizations are—in the final analysis—a theological opinion. They are not infallible, as explained in this 2014 article by a priest (with a doctorate in theology) who worked for multiple popes. Mr. Keating says: “I’m unaware of such claims arising from any quarter until several recent popes disliked by these Traditionalists were canonized, including John XXIII, Paul VI, and John Paul II. Usually Paul VI receives the most opprobrium.” Mr. Keating is incorrect; e.g. Father John Vianney, several centuries ago, taught clearly that canonizations are not infallible. Archbishop Fulton J. Sheen would be another example, although clearly much more recent than Saint John Vianney.

    Vatican II Changed Wedding Propers?
    It’s often claimed that the wedding propers were changed after Vatican II. As a matter of fact, that is a false claim. The EDITIO VATICANA propers (Introit: Deus Israel) remained the same after Vatican II. However, a new set of propers (Introit: Ecce Deus) was provided for optional use. The same holds true for the feast of Pope Saint Gregory the Great on 3 September: the 1943 propers (Introit: Si díligis me) were provided for optional use, but the traditional PROPRIA MISSAE (Introit: Sacerdótes Dei) were retained; they weren’t gotten rid of. The Ordo Cantus Missae (1970) makes this crystal clear, as does the Missal itself. There was an effort made in the post-conciliar years to eliminate so-called “Neo-Gregorian” chants, but (contrary to popular belief) most were retained: cf. the feast of Christ the King, the feast of the Immaculate Conception, and so forth.
    —Corpus Christi Watershed
    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).
    —Corpus Christi Watershed

Random Quote

“Urban VIII appointed four Jesuits to reform the hymns, so that they should no longer offend Renaissance ears. These four, in that faithful obedience to the Holy See which is the glory of their Society, with a patient care that one cannot help admiring, set to work to destroy every hymn in the office.”

— Fr. Adrian Fortescue (1916)
