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.”

Biography • Dr. Gregory Hamilton

Dr. Gregory Hamilton · July 20, 2020

REGORY HAMILTON enjoys a wide variety of activities and interests as a composer, recitalist on the organ, piano and harpsichord, as a conductor, and continuo player on the harpsichord and theorbo. He is skilled in improvisation, and frequently includes improvisation in concerts. As a composer, over 100 of his works are in publication by Morning Star, Augsburg Fortress, CanticaNova, WLP, Concordia, Paraclete Press, Sheet Music Plus, and Lorenz, and are presented internationally in concert halls and churches, schools and airports. His Breath of the Spirit (an evening-length work for flute and organ, with narrators, written with Poet Kenneth Gaertner) was commissioned by Marilyn Mason and premiered by her with the flutist Donald Fishel in the Paris Festival Toussant at the Cathedral of Notre Dame de Paris, and has been performed over twenty times in the U.S and Europe.

Gregory was commissioned to compose The Church’s One Foundation for the Archdiocesan choir and orchestra for the dedication of the Cathedral of the Sacred Heart in Houston. Other recent works premiered include Concerto for Cello and Orchestra (Diane Winder and the Ypsilanti Symphony), Five Psalm Pictures, Rosary (Premiere—St. Johannes church, Amsterdam) and Fantasy Variations on a Theme of Schubert for string trio and flute, Hymn of Peace for Cello and Piano (cellist Cellist Mirel Iancvici; professor of cello at the Conseratoriaum, Utrecht) and several works for Houston virtuoso Organist Jackson Osborn. Gregory Hamilton attended Baldwin-Wallace University (B.MUS) The Royal College of Music, London, (M.Mus, A.R.C.M.) and The University of Michigan, (DMA) where he was a scholarship student of Dr. Marilyn Mason. Gregory has researched the works of Dom Paul Benoit, (1895-1976) the French composer-organist and has performed many of his works in the U.S. and abroad, including research at Benoit’s monastery, St. Mark and St. Maur in Clervaulx, Luxembourg. With Dr. Hamilton’s recent CD releases of Benoit’s music on RosaMystica recordings, he is enjoying the welcome upsurge in interest in the works of Benoit. Dr. Hamilton’s music has been featured in many radio broadcasts, including the NPR show Pipedreams, and was recently interviewed on “Notes from Above” (Ave Maria Radio). As a conductor, he has a wide repertoire of both choral and orchestral works, and has studied conducting with Dr. John Robinson and Dr. Leonard L. Riccinto.

    Music List • (Palm Sunday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Palm Sunday—a.k.a. “Dominica in palmis de Passione Domini”—which is 29 March 2026. Please feel free to download it as a PDF file if such a thing interests you. The OFFERTORY (Impropérium exspectávit cor meum) is quite moving. Even though the COMMUNION ANTIPHON is relatively simple, the Fauxbourdon makes it sound outstanding.

    Easter • Would You Sing This Hymn?
    He who examines Laudes Dei: a hymnal for Catholic congregations (St. Louis, 1894) will discover this pairing of a hymn for Easter. For the record, this isn’t the only Catholic hymn book to marry that text and melody; e.g. Saint Mark’s Hymnal for Use in the Roman Catholic Church in the United States (Peoria, 1910) does the same thing. Sometimes an unexpected pairing—chosen with sensitivity—can be superb, forcing singers to experience the text in a ‘fresh’ and wonderful way. On the other hand, we sometimes encounter something I’ve called “PERNICIOUS HYMN PAIRINGS.” If you find the subject in intriguing, feel free to peruse an article I published in May of 2023. As always, my email inbox is open if you have a bone to pick with my take.

    Pipe Organ “Answers” in Plainsong?
    In 2003, I copied a book by Félix Bélédin (d. 1895), who was titular organist—from 1841 to 1874—at the Cathedral of Saint John the Baptist in Lyon (France). In 2008, we scanned and uploaded the book to the Lalande Online Library. Nobody knows for sure when the book was published; some believe it first appeared in the 1840s. In any event, one who examines this excerpt, showing GLORIA IX might wonder why it says the organ answers in plainsong. However, the front of the book explains, telling the organist explicitly when to “respond in plainchant.” This is something called organ alternatim. Believe it or not, the pipe organ would take turns with the choir, playing certain texts instrumentally instead of having them sung. I’m not very well-versed in this—pardon the pun—but if memory serves, ORGAN ALTERNATIM was frowned upon by the time of Pope Saint Pius X. Nevertheless, French organists kept doing it, even after it was explicitly condemned as an abuse.

Quick Thoughts

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

[Speaking about the Silent Canon, with audible “per ómnia”] — “So in all such cases it is usual for the otherwise silent celebrant occasionally to sing a clause aloud, to show how far he has arrived.”
