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.”

An Interview with Bruno de Labriolle

Readers interested in different stylistic approaches to Gregorian chant may enjoy this interview with the singer Bruno de Labriolle, who directs the schola of Saint-Bruno-des-Chartreux in Lyon. The views on chant and liturgy aired in the interview aren’t exactly the same as those of any of our contributors, but I personally find this group’s performances, in […]

Gregorian Rhythm Wars • “Weaver Responds to Williams”

“Nothing so arouses the soul, gives it wing, sets it free from the earth, releases it from the prison of the body, teaches it to love wisdom, and to condemn all the things of this life, as concordant melody and sacred song composed in rhythm.” —St. John Chrysostom

President’s Corner

    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.
    —Jeff Ostrowski
    PDF • “Communion” (5th Sunday in Ordin.)
    The COMMUNION ANTIPHON for this coming Sunday, 8 February 2026—which is the 5th Sunday in Ordinary Time (Year A)—is truly delightful. You can download the musical score completely free of charge. This text will be familiar to altar boys, because it’s PSALM 42. The Feder Missal makes the following claim about that psalm: “A hymn of a temple musician from Jerusalem: he is an exile in a heathen land, and he longs for the holy city and his ministry in the Temple there. The Church makes his words her own.”
    —Jeff Ostrowski
    Funeral Music “Template” • For Families
    Many have requested the MUSICAL TEMPLATE for funerals we give to families at our parish. The family of the deceased is usually involved in selecting Number 12 on that sheet. This template was difficult to assemble, because the “Ordo Exsequiarum” has never been translated into English, and the assigned chants and hymns are given in different liturgical books (Lectionary, Gradual, Order of Christian Funerals, and so on). Please notify me if you spot errors or broken links. Readers will be particularly interested in some of the plainsong musical settings, which are truly haunting in their beauty.

Quick Thoughts

    “Reminder” — Month of Febr. (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. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    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

If it is the explicit will of the Council that the faithful are to be able to sing the “Gloria” or the “Credo” together in Latin [which it is] then indirectly there is being expressed here the obligation of regularly celebrating Mass with Latin Gregorian chant. And not merely occasionally, but with such frequency and constancy as to make the singing of these Latin texts a genuine possession of the faithful.

— Heinrich Flatten, Apostolic Protonotary & Canon Law Professor (Bonn)
