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.”

Mass Among the Poor

Does it seem strange that religious orders dedicated to serving the poor would also be rediscovering the traditional Latin Mass?

The Awesomeness of the Holy Sacrifice of the Mass

A Benedictine monk helps us appreciate the tremendous miracle of the Mass, which is the central point of all earthly reality.

Why the Mass is the Key to the New Evangelization

We hear a lot these days about the New Evangelization, but not so much about the Holy Sacrifice of the Mass. And yet the Mass is at the very heart of our mission.

Important Resources for Liturgical Reform (7 of 7)

“Who could have anticipated such a Renaissance of music-making in the desert of postmodernity? Yet this was but the first wave, and now we are enjoying a second…”

St. Thomas on the “Asperges” (Sprinkling Rite)

St. Thomas did not comment specifically on the custom of sprinkling the people with holy water prior to the principal Sunday Mass; but he did explain exactly why it’s a good idea to do such a thing.

Away with the World—Let Heaven Enter

Music, for a Christian, should serve the same purpose as everything else in life: weaning us from excessive attachment to this world and lifting our souls heavenward.

Dr. Peter Kwasniewski · July 24, 2014

“What Shall I Render to the Lord…”

It is impossible for us, by ourselves, to make a just return to the Lord for all He has given to us. But “with the Lord, nothing is impossible.”

Basic Steps To Improve Music At Your Parish — Part 2

I have been asked to recommend some ways in which any parish in the United States could improve the music used at Mass. Some parishes may already have taken the following two steps, in which case my advice will be nugatory for them, but if your parish has not yet done so, now’s the time to begin.

Music Rules Over Us

Music is like a food that either makes us healthy or sick; indeed, it shapes our souls in its image.

On the Objectivity of the Beautiful

Can we really rank the works of fine art? Is one composer greater than another, one piece of sacred music more beautiful than another? Or is it all relative?

Archbishop Sample’s Letter On Sacred Music (4 of 8)

The Danger of Being Arbitrary in the Liturgy

Traditional practices form a coherent whole, as they developed organically together. In many ways the liturgical reform was mechanistic and ideological.

    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

“With all the powers of modern music open to him, from romanticism through French impressionism to the German and Russian modernists, he is yet able to confine all these contradictory forces on the groundwork of the Gregorian tradition.”

— Theodor Rehmann (on Msgr. Jules Van Nuffel)
