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.”

Notice how the priest, dressed in cope, is engulfed in darkness at the beginning of the Easter Vigil—except for candles burning.

It Has Arrived! • “Proper of the Mass” (Ignatius)

You will notice that Fr. Weber’s version sounds quite similar to the authentic Latin chant.

Bells are rung and the organ played at the “Gloria”—but then stay silent until the Easter Vigil “Gloria.”

What Happened To Our Catholic Artists?

From what I can tell, a trend toward *ugly* artwork in Church publications began in the late 1950s.

President’s Corner

    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

“I am now old but I was young when I was received into the Church. I was not at all attracted by the splendour of her great ceremonies—which the Protestants could well counterfeit. Of the extraneous attractions of the Church which most drew me was the spectacle of the priest and his server at Low Mass, stumping up to the altar without a glance to discover how many or how few he had in his congregation; a craftsman and his apprentice; a man with a job which he alone was qualified to do.”

— Evelyn Waugh (7 August 1964)
