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.”

Gregorian Rhythm Wars

Gregorian Rhythm Wars • “Non Praevaleat”

“We got to this point because we questioned unfounded claims.” —Patrick Williams

Jeff Ostrowski · March 18, 2023

Sneaky “Salicus” Statements by Solesmes

Let there be no mistake about it: Dom Mocquereau (illicitly) added the “salicus” in hundreds of places where the official edition has none.

Patrick Williams · March 15, 2023

Ictus Fictus!

“Hardly any of this made-up system has its basis in medieval music theory or in the manuscripts themselves.”—Patrick Williams

Dr. Charles Weaver · March 13, 2023

Rhetoric, Number, Measure, and Historicism

The beginnings of a response to mensuralism from the classic Solesmes point of view.

Patrick Williams · March 10, 2023

Gregorian Rhythm Wars • “Clap Your Hands!” (10 Mar 2023)

“With my questions unanswered by those objecting to rhythmic markings based on the oldest sources, it is difficult to take their arguments seriously.” —Patrick Williams

Patrick Williams · February 15, 2023

Gregorian Rhythm Wars • “Liturgical Recitative” (15 Feb 2023)

“May our voices be the instruments through which God breathes new life into the ancient chants of the Catholic Church, decrepit through centuries of neglect and misinterpretation!” —Patrick Williams

Patrick Williams · February 7, 2023

Gregorian Rhythm Wars • “The Normal Syllabic Value” (6 Feb 2023)

“The problem with semiology is not that it neglects the rhythmic indications of the oldest sources, but rather that it overinterprets them, like the nuance theory on steroids.” —Patrick Williams

Patrick Williams · January 2, 2023

Gregorian Rhythm Wars • “Chorale and Chant Carefully Considered” (2 Jan 2023)

“The equalist plainchant of the High Middle Ages is as far removed from the rhythmic chant of the Early Middle Ages as the isometric chorales are from their rhythmic predecessors.” —Patrick Williams

Patrick Williams · December 19, 2022

Gregorian Rhythm Wars • “Patrick’s Third Response to Jeff” (19 Dec 2022)

“The original chant handed down from the Fathers of the Church has strict rhythmic proportions and a steady beat.” —Patrick Williams

Matthew Frederes · December 12, 2022

Recent Book! • “The Politics of Plainchant”

Fascinating details from never-before-seen letters recently discovered in southern France!

Jeff Ostrowski · December 10, 2022

PDF Download • “Kyriale Accompaniment Book” by Dr. Peter Wagner (138 pages)

… including a deliciously dazzling discovery you won’t want to miss!

Dr. Charles Weaver · December 8, 2022

Gregorian Rhythm Wars • “The Limits of History”

There’s nothing necessarily authentic about the “authentic” rhythm.

Jeff Ostrowski · December 7, 2022

PDF Download • “Salve Regina” [Simplex] • An Elegant English Translation (2022)

The incomparable Andrew Hinkley kindly set it to plainchant notation.

Jeff Ostrowski · December 6, 2022

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.

Patrick Williams · November 30, 2022

Gregorian Rhythm Wars • “History Matters” (30 Nov 2022)

“It is important that these melodies should be performed in the manner that they were originally conceived as works of art.” —St. Pius X

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.
    —Jeff Ostrowski
    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st Sunday of Lent (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 outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.
    —Jeff Ostrowski
    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!
    —Jeff Ostrowski

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”
    —Jeff Ostrowski
    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

Random Quote

By far, the event that caused the biggest increase in requests for indults from the morning Mass requirement was the Second World War. The unusual requirements of providing Mass during wartime led to some unique legislation accommodating the time of Mass. Already in 1940, Pope Pius XII issued a motu proprio addressing the situation of holding Mass in countries where a “Black-out” had been ordered.

— Father Shawn P. Tunink
