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.”

The “O Antiphons” Begin Tonight

Andrew Leung · December 17, 2015

CTL O Antiphons ODAY IS DECEMBER 17. It is seven days before Christmas Eve. Today is the day that Advent gets even more intense. The Church have chosen special Antiphons and Readings for the coming week to help us prepare the coming of Christ. The “O Antiphons“ are a set of antiphons for Vespers that is prayed during the coming seven days.

The reason why they are called the “O Antiphons“ is because each of them start with the letter “O”. In the Liber Usualis, they are called the “Great Antiphons”. They were mentioned in the 6th century and they were used in Rome by the 8th century. The texts of these antiphons are from the Old Testament Prophetic and Wisdom Books. These antiphons are recited or sung before and after the Magnificat, or the Canticle of Mary. Each of the antiphons begins by calling out a title of Christ:

O Sapientia………….O Wisdom

O Adonai……………..O Lord

O Radix Jesse………O Root of Jesse

O Clavis David……..O Key of David

O Oriens……………..O Dayspring/Dawn

O Rex Gentium…….O King of Nations

O Emmanuel………..O Emmanuel (God is with us)

There is a very cool fact about these titles. If you take the first letters of each titles and spell out from the last one, you will get: “EROCRAS”. And the Latin words “ero cras” means “I will be (there) tomorrow”. Here are the pages of the Great Antiphons from the Liber Usualis (Solesmes 1957) with English translations:

CTL James MacMillan OWADAYS, many of us still sing the “O Antiphons” in Advent, just in a different setting. The text of the famous Advent hymn, O Come, O Come Emmanuel, is from the Great Antiphons. And actually, Jeff Ostrowski just wrote about the Original Setting of the Tune yesterday.

As I was searching through other pieces that are related to the Great Antiphons, I found this Percussion Concerto below. The concerto, “Veni, Veni, Emmanuel“, was composed by Sir James MacMillan, a leading composer who have just been named Catholic of the Year by the Catholic Herald magazine. He has written music for Pope Benedict’s visit to England in 2010 and he has been commissioned recently to write a work for Shrine of Fátima’s centenary which will be attended by Pope Francis. James MacMillan is also the founder of Musica Sacra Scotland, an organization that promotes Gregorian Chant in Scotland.

The Scottish composer took the tune of the hymn as the theme of his work. It is a very interesting and intense piece! It is a non-liturgical piece. But one can listen to it and meditate on Mary and Joseph’s intense and difficult trip right before the birth of our Lord.

    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).

    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

“But when all aids to a good translation of the Psalms have been made use of, it often happens, from various causes, that some words or phrases of a Psalm remain obscure or unintelligible to the reader. Then it is that explanatory Notes become necessary.”

— Father Charles J. Callan (who founded “The Homiletic and Pastoral Review”)
