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.”

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!”

“1950s Catholicism” • Do We Want It Back?

“I have found, to my astonishment, that Catholics…in their principal churches, do not to this day possess even one Mass setting even tolerably good, or which is not actually distasteful and operatic.” —Felix Mendelssohn (1835)

FEEDBACK • “Soul Was Craving”

I got this (personal) message from a choir member. I know we usually avoid sharing personal items, but hopefully this exception is warranted: “Dear Mr. Ostrowski, I read your recent article, “I Came From Somewhere.” I really enjoyed reading it. Thank you for all that you do. I appreciate your sentiments and your work to […]

Plainsong sung poorly—in a sluggish, lifeless manner—can leave a bad taste in people’s mouths.

“Repugnant Pairing” (In My View)

We have spoken many times about the common tunes contained in the Saint Jean de Brébeuf Hymnal. I have suggested that these “shared melodies” are crucial for any director attempting to build a serious choral program in today’s environment. However, I’ve also said hymn pairings must be done with great sensitivity. Take a look at […]

“Truly Bizarre!” • Easter Vigil on Easter Sunday?

Rather than allow the traditional times, the Vatican gave permission to allow the Easter Vigil to be celebrated on the morning of Easter Sunday!

    PDF Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    “Reminder” — Month of May (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. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

Random Quote

The “Nova Organi Harmonia” demanded from each of us an unusual commitment; we have dedicated to it the best of our energies. Would it be, therefore, presumptuous on our part to be satisfied with the result and to expect its welcome reception in the musical world?

— Msgr. Jules Van Nuffel (circa 1940)
