President’s Corner

    “Reminder” — Month of July (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.

    Music List • (15th Sund. Ordinary Time)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for the 15th Sunday in Ordinary Time (Year A), which is 12 July 2026. Please feel free to download it as a PDF file if that appeals to you. The hymns chosen are some of the most ‘traditional’ I have chosen (and were chosen by our pastor). The ENTRANCE CHANT radiates pure bliss, overflowing with joy.
    —Jeff Ostrowski
    Shortest Psalm In The Bible
    The shortest chapter in the whole Bible—as well as the shortest psalm—is PSALM 116 (“Laudáte Dóminum ómnes géntes”), which consists of just two verses. German-speaking Catholics did something really splendid (PDF) with PSALM 116. I was alerted to this many years ago by none other than Monsignor Robert Alexander Skeris. Click here to download—from different Catholic hymn books—ten (10) different harmonizations for this fabulous hymn.

Quick Thoughts

    ‘Ould’ But Not Good
    Dom Samuel Gregory Ould (note the spelling) was a Benedictine monk at FORT AUGUSTUS ABBEY in Scotland. As musician, organist, and composer, Dom Ould was highly regarded. Moreover, he was considered an authority on Gregorian Chant. But not everything found in an old book—or, in this case, an “Ould” book—is necessarily praiseworthy. Consider this page from Dom Ould’s hymnal. Do you see the rhymes? They offend severely by ABR (“Abuse By Reuse”) and are utterly predictable. In my recent article—Two Ways to Defile a Hymn—I addressed this topic.

    “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

“It is the same Church which has introduced the vernacular into the sacred liturgy for pastoral reasons, that is, for the sake of people who do not know Latin, which gives you the mandate of preserving the age-old solemnity, beauty and dignity of the choral office, in regard both to language, and to the chant.”

— Pope Saint Paul VI (15 August 1966)
