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.”

Too Much Emphasis On Liturgy? • A Response

Perhaps the supposed over emphasis on the Liturgy among younger Catholics today is just a response to its devaluation since the 1960s.

Tone Quality and Your Singers

Ultimately it doesn’t matter if your choir resonates well and sings beautiful vowels but can’t communicate via the music…

Building Your Choir Vocally

If more choirmasters were honest with themselves, they would probably acknowledge that no more than 25 to 40 percent of their singers are actually leaders within their choirs.

Review • Fr. White’s Tools for Rebuilding

I’m edified by Fr. White’s work, but hope his regard for “church growth” doesn’t negate the Sacramental and supernatural nature of the Church.

Whether a Gothic cathedral in France, a rural Norman church in England or a Californian mission church, each one in its own way has the power to lift our eyes in contemplation of the New and Eternal Jerusalem.

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday—1 March 2026—the 2nd 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 flourishing feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    Particularly Beautiful
    The 2nd Sunday of Lent has magnificent propers. Its INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.
    —Jeff Ostrowski
    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.
    —Jeff Ostrowski

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.
    —Corpus Christi Watershed
    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

“Only against this background, of the effective denial of the authority of Trent, can one understand the bitterness of the struggle against allowing the celebration of Mass according to the 1962 Missal after the liturgical reform. The possibility of so celebrating constitutes the strongest, and thus (for them) the most intolerable contradiction of the opinion of those who believe that the faith in the Eucharist, as formulated by Trent, has lost its validity.”

— Cardinal Ratzinger, 2001
