“Hidden Chant” • For the Ordinary Form

Not even “GregoBase”—which is incredibly comprehensive—knows that music for this antiphon was published by the Vatican in the 1930s.

    “Hidden Chant” • For the Ordinary Form
    If you have carefully examined the gorgeous ORDO MISSAE—in full color—for the Jogues Illuminated Missal, Gradual, and Lectionary, you probably noticed that the Ordinary Form gives several different optional texts for the ASPERGES ME, whereas the 1962 Missale Romanum only has one. One of them is called Effúndam super vos aquam. I always wondered whether Gregorian Chant existed for this antiphon. Well, it turns out the Vatican published a plainsong version of this antiphon in the 1930s: PDF Download (‘Effúndam’). Not even “GregoBase”—which is incredibly comprehensive—knows about this antiphon.

    “Citation Needed” • Dom Foote of ICEL
    Father Basil Foote, OSB, was organist at WESTMINSTER ABBEY MISSION (British Columbia, Canada). In 1984 he published an article called “Chanting in the Vernacular.” Twenty years later, it was republished by ADOREMUS—and that’s how it came to my attention. In that article, Dom Foote makes a claim I consider somewhat outlandish. At the very least, his statement with regard to the Latin accent needs some sort of citation. He has served on the Music Sub-Committee of the International Commission on English in the Liturgy (ICEL).

    Music List • “Corpus Christi” (Year A)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for the Feast of Corpus Christi—a.k.a. “Feria V post Ss.mam Trinitatem”—which is 7 June 2026 in the United States. You can download it as a PDF file if that appeals to you. Our children’s choir will join us for this Mass. I’m not sure I know a more beautiful setting than the ENTRANCE CHANT, which comes from Psalm 80 (“Exsultáte Deo adjutóri nostro”). Although it’s rather ugly—because I didn’t have time to clean everything up—feel free to download the SINGER’S PDF BOOKLET (28 pages), in case anything therein gives you inspiration.

Quick Thoughts

    Time and Again We Are Asked…
    John Baptist Singenberger (d. 1924) was a central figure of Catholic Church music. In this utterly fascinating excerpt (Single-Page PDF), Singenberger writes: Time and again we are asked: “Is the Gregorian chant to be accompanied by the organ?” As a young student in Saint Gall, Singenberger befriended SEBASTIAN GEBHARD MESSMER, the future Archbishop of Milwaukee (Wisconsin). The two graduated together in 1861. The school they attended (Saint George’s Seminary) was a “seminary”—but in the older European sense. In other words, it provided a classical education without necessarily leading to ordination. Singenberger remained a layman his whole life, but Messmer was eventually made archbishop—by Pope Saint Pius X—of the very archdiocese in Wisconsin where Singenberger would spend his American career, giving him a powerful ecclesiastical ally.

    “Reminder” — Month of June (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). Since we were founded in 2006, not one of our board members has ever accepted any remuneration whatsoever—not a penny. 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.

    “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).

Random Quote

“When formerly our churches were poor, and the means of presenting the services of the Church limited, there may have been a strained excuse for the light and unecclesiastical music so often heard…”

— Most Rev’d Richard Gilmour, Bishop of Cleveland (13 April 1886)
