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.”

Unified Repertoire | Piano, Guitar, and Organ Accompaniments for the ICEL Chants

Richard J. Clark · July 11, 2014

N 2011, IN PREPARATION for the implementation of the new translation of the Roman Missal, I was busy giving workshops on “Singing the Mass” with Fr. Jonathan Gaspar, the Director of the Office of Divine Worship in Boston. We traveled around the Archdiocese, visiting several parishes. We sang through the new ICEL Chants, and touched upon topics both musical and liturgical. The idea of “singing the mass” was foreign to many. The idea of singing chant was even more foreign, no less unaccompanied! But the good people who came were open minded and eager to learn.

BUT WHAT WAS TRULY A DIVIDE were the many piano/guitar-based ensembles that felt left in the dark. You see, in Boston, the use of the ICEL chants was to be exclusive for a time. No other setting could be used in the time leading up and for a time after the implementation. So to help bridge that gap, I arranged a few piano/guitar accompaniments and distributed them for free for anyone who requested them.

Now, a few years later, I am discovering that a number of piano/guitar-based* groups are still singing the ICEL Chants of The Roman Missal, Third Edition from time to time. *(Note that I am avoiding the term “contemporary ensemble”. I dislike that term along with a casual use of the word “traditional.” The guitar is as ancient as the organ. There is traditional music of all styles. All music written today is contemporary. These generalizations are all very silly.)

HE IDEA OF THE ICEL CHANTS of The Roman Missal, was to have a common musical repertoire among seventeen English speaking countries around the world. That covers much of the Earth! As such, if the ICEL chants are sung from time to time at all masses in a parish, it fosters unity within that parish. This can be a pragmatic advantage as well as a spiritual one, as that parish becomes more united in prayer with much of the world. Furthermore, it helps a parish avoid being multiple (and separate) communities under the same roof. Therefore, below are three useful resources:

1 • These piano/guitar arrangements are written stylistically for those not used to singing chant and modal music. There are also some editorial adjustments to assist in timing and breathing.

      * *  ICEL Chants | Piano, Guitar Accompaniments | Richard Clark • Roman Missal, Third Edition

2 • Exceedingly useful are the Chants from the Order of Mass by Charles Thatcher, published by World Library Publications. (WLP also makes it available as a digital PDF download.) Thatcher has struck a perfect balance between preserving the modality in an organ accompaniment, while providing matching guitar chords. With regard to unity, these accompaniments work perfectly with organ and guitar together. If you have not tried such a thing, please do. Strings on the organ with guitar make for a beautiful texture.

3 • Exquisite and steeped in modality are Jeff Ostrowski’s accompaniments. As always, Jeff is exceedingly comprehensive, providing no fewer than four accompaniments for the various forms of the Our Father. He also includes the Latin versions upon which the ICEL Chants are based, a wonderful addition.

      * *  ICEL Chants | Organ Accompaniments | Jeff Ostrowski • Roman Missal, Third Edition

Finally, here are recordings and practice videos of the ICEL Chants of The Roman Missal, Third Edition (including the Exsultet). Recorded at St. Cecilia Church in Boston, the four seconds of delay require the pacing and breathing to be a bit broader. Fr. Jonathan Gaspar sings the celebrants’ parts.

The chants are sung unaccompanied in this recording. Interestingly, I find that congregations sing these best when unaccompanied! Accompaniments can be a security blanket and even necessary at times. But in due season, let it go, and sing out!

I hope this is all of some use in praying the words of the Mass.

    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!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

    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.

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

Random Quote

“The liturgy needed reform by 1965; there was no call for dismantling it. It was intended that the vernacular would enhance the Latin, not supplant it. It was not, emphatically, the mind of the Council Fathers to jettison Gregorian Chant, or to encourage the banal secularization of Church music, so as now to surpass in crudity the worst aberrations of the Howling Pentecostals.”

— Most Rev’d Robert J. Dwyer, Archbishop of Portland (9 July 1971)
