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.”

My choir will definitely be using these settings. They’re something many have begged for!

“Solesmes Ictus” • Can It Be Justified? (Examples)

“If you begin by telling a man that in a word like 𝐷𝑒𝑢𝑠 the first syllable corresponds to the weak beat, the second to the strong beat of a modern bar, the only thing accomplished will be to bewilder him thoroughly.” —Father Bewerunge

Dr. Charles Weaver · January 26, 2023

What is the Tonic Accent?

We should define our terms. What makes a syllable accented, and what makes an accent a tonic accent?

Video • “Counting Gregorian Chant” … according to Dom Mocquereau’s Method

The example chosen is the strenuous offertory (“Jubiláte Déo”) for the 2nd Sunday after Epiphany.

Jeff Ostrowski · January 5, 2023

“Solesmes Method” • Where was it developed?

Father Ralph March wrote: “If any single man could deserve the title father of the renewed chant it would be Dom Joseph Pothier.”

Gregorian Rhythm Wars • “Jeff’s Second Response to Patrick” (6 Dec 2022)

You look upon these thousands of manuscripts in much the same way that I view the plainsong editions of Guillaume-Gabriel Nivers.

Matthew Frederes · November 10, 2022

Gregorian Rhythm Wars • “Frederes Feedback”

Why declare that rhythmic signs are permitted if alteration of any kind is unacceptable? It doesn’t make any sense…

Jeff Ostrowski · August 29, 2022

“Did The Pope Really Say That?” • Re: Solesmes Rhythm

President’s Corner

    “Lamb of God” (Musical Setting)
    The MASS OF SAINT ANNE LINE has been quite popular ever since ROMAN MISSAL Third Edition was released circa 2011. You can now download the musical score (PDF) for this setting, placed into five (5) different keys; i.e. “pitch levels” that are high and low. This makes it possible to adjust based upon who’s singing at which time of day.
    —Jeff Ostrowski
    PDF Download • Introit (2nd Sn. Ord.)
    This coming Sunday, 18 January 2026, is the 2nd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT is set according to the fourth mode, which sounds ‘serious’ or ‘dark’ or ‘haunting’ or ‘mysterious’—and its English adaptation corresponds to the authentic version (“Omnis terra adóret”) found in the GRADUALE ROMANUM. In this rehearsal video (click here) I attempt 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 the harmonies are delightful.
    —Jeff Ostrowski
    Spectacular Communion Setting!
    The FAUXBOURDON setting of the Communion for the Baptism of the Lord (which will occur this coming Sunday) strikes me as quite spectacular. The verses—composed by the fifth century Christian poet, Coelius Sedulius—come from a long alphabetical acrostic and are deservedly famous. The feast of the LORD’S BAPTISM was traditionally the octave day of Epiphany, but in the 1962 kalendar it was made ‘more explicit’ or emphasized. The 1970 MISSALE ROMANUM elevated this feast even further.

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.
    —Jeff Ostrowski

Random Quote

“The Pope is not an absolute monarch whose thoughts and desires are law. On the contrary: the Pope’s ministry is a guarantee of obedience to Christ and to his Word. He must not proclaim his own ideas, but rather constantly bind himself and the Church to obedience to God’s Word, in the face of every attempt to adapt it or water it down, and every form of opportunism.”

— ‘His Holiness, Pope Benedict XVI (11 May 2005)’
