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.”

“Homily for the Feast of Christ the King” (EF) • Father Valentine Young, OFM

In many of His parables and teachings, Christ let us know that His Kingdom on earth was always what I am going to call “an unfinished product.”

20 October 2020 • “What we can’t share”

Almighty God has given to us the example of the Jesuit Martyrs of North America, whose feast day we celebrated yesterday. Of course, along with those eight martyrs we honor their associates, e.g Father François Bressani. I can’t share with you the torments Father Bressani underwent at the hands of Iroquois: it is too brutal. […]

19 October 2020 • Feast of Father Brébeuf

When the young priest saw the burnt and bleeding body of his superior, aghast and trembling he spoke the words of St. Paul: “We are made a spectacle to the world, to angels and to men.”

Dom Pothier • “To The Eyes And To The Ears”

For years, I couldn’t understand this business about “the eyes and the ears.” What did Pothier mean? Then it hit me. • Topics include Dom Joseph Pothier, the mora vocis, Abbot Pothier’s brother (Dom Alphonse Pothier), Dom Lucien David, Dom Paul Jausions, and a truly magnificent story about Pope Pius X and Abbot Pothier, which is essential reading+

The “Mora Vocis” • What is that?

The “Pre-NOH” editions have quite an idiosyncratic way of lengthening the neumes. • Fulsome illustrations are included examining and explaining the mora vocis of the Vatican edition; also mentioned is Dom André Mocquereau, Rafael Cardinal Merry del Val, and Pothier’s Liber Gradualis (1883)+

13 October 2020 • Chopin talks Bach

My “pianist pedigree” goes from my teacher through Wiktor Łabuński through Felix Blumenfeld, who studied with Anton Rubinstein. I always considered myself part of the “Bach-Mozart-Chopin school” as opposed to the “Handel-Beethoven-Liszt school.” (Needless to say, there’s great overlap between these schools.) Before giving a concert, Frédéric Chopin would always shut himself up in a […]

12 October 2020 • True Story

Before a Low Mass, the priest ascends the Altar to place the Chalice, check the altar Missal, and do other “preparing” tasks. The organist must be prepared to play here, and—depending upon the priest—this can be of surprising length! For certain priests, I can easily play all six verses of a hymn while he’s doing […]

“Homily for the 19th Sunday after Pentecost” (EF) • Father Valentine Young, OFM

The word “grace” means a gift given to us by God. Sanctifying grace is first given to us when we are baptized.

“O Sacrum Convivium” • Recorded by one person

    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
    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.

    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.

Random Quote

“The argument moves from the existence of the thing to the correctness of the thing: what is, ought to be. Or, a popular variant: if a thing is, it doesn’t make any difference whether it ought to be—the correct response is to adjust, to learn to live with the thing.”

— ‘L. Brent Bozell, Jr.’
