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.”

Dom Gajard said to Jean Langlais: “Hear the blackbird! It doesn’t know what an ‘ictus’ is, yet it sings better than we.”

Dr. Charles Weaver · November 13, 2022

Gregorian Rhythm Wars • “Charlie’s First Response to Jeff” (13 Nov 2022)

Ostrowski, wishing to avoid fussiness, may justifiably refuse this invitation. But to argue, as he has, that these signs and the prayerful and aesthetic movements they embody are “illicit” is just wildly off the mark.

    Music List • (3rd Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday: the 3rd Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.
    —Jeff Ostrowski
    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

Quick Thoughts

    “Reminder” — Month of January (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). 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. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.
    —Jeff Ostrowski
    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

“No living writer possesses a greater command over the English language than Msgr. Knox, but in this instance one cannot help feeling that he has allowed his virtuosity to get the better of him, and, in his anxiety to shield the holy of holies from vulgar intrusion, produced a text that would either pass over the listener’s head as completely as the original Latin, or else leave him groping so long after the meaning that he would be quite unable to keep pace with the officiating priest.”

— Dr. Herbert Patrick Reginald Finberg (University of Leicester)
