President’s Corner

    Oldest Latin Eucharistic Hymn
    The Church’s oldest Latin Eucharistic hymn is featured in the Brébeuf Hymnal. Indeed, the legendary Father Adrian Fortescue made a translation of it—matching the original’s meter—which was elevated by the Brébeuf team. For years, we’ve been working on a Spanish hymnal: “Cantoral del Padre Antonio Daniel.” The progress has been slow but steady, and we encourage anyone fluent in Spanish to consider joining the proofreading team. A few days ago, my wife helped me record a rehearsal video for this Spanish version of the Church’s oldest Latin Eucharistic hymn.

    Rare Plainsong Accompaniments
    Our contributor, Veronica Brandt, went deep into Australia to take photographs of organ accompaniments for Gregorian Chant. Some consider these peculiar PLAINSONG ACCOMPANIMENTS—with 3-part harmonies by Barcelona Cathedral organist, Father Josep Muset i Ferrer—to be the rarest in the world. Click here to learn more. Thanks Veronica! 😊

Quick Thoughts

    “Reader Feedback” • 22 June 2026
    A reader wrote to us from Virginia: “I really appreciate the 23 harmonizations that you posted on CORPUS CHRISTI WATERSHED for the Daily, Daily, Sing to Mary hymn. I hope to find willing voices in our small Schola Cantorum to try the three-voice version. Carry on, sir! You’re doing the Lord’s work.” While we don’t know this gentleman personally, we note that he earned a Ph.D. (which demonstrates that our blog has something for everybody). 😊

    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.

Random Quote

“One can still have silence even during the Canon, since one is not obliged to recite the Canon audibly at all times. A quieter, less powerful tone of voice will always permit an opportunity for personal, silent prayer.”

— Joseph Cardinal Frings (25-jan-1968), patron of “Consociatio Internationalis Musicae Sacrae” (papal church music association)
