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.”

Schola Director Posts ‘Live’ Recording

As I explained in my article posted earlier today, Nun Komm Der Heiden Heiland is actually a Catholic tune (in spite of what some have claimed). The volunteer choir I direct sang that beautiful ADVENT melody last Sunday, and I invite you to listen to the live recording. It will get better the more we […]

Dr. Buchholz says: “Those settings are absolutely exquisite, as I’m used to when […]

Requesting Our Advent Eucharistic Hymn

A young lady named Agnes wrote to us: “Dear Mr. Ostrowski, do you have the PDF score for Ave Corpus Domini set to the ADVENT melody?

Seven (7) Hymn Verses for November!

In the month of November, we remember in a special way the souls in purgatory. The BRÉBEUF HYMNAL often includes text alone versions for its hymns; why is that? The short answer is: flexibility. The “text only” version allows each choirmaster to employ a myriad of melodies. For example, I recently set the English translation […]

PDF • Morley’s Choral “Warm-Up”

For decades, I was against choral warm-ups. I felt they should be derived from repertoire—killing two birds with one stone—but was often too lazy to prepare such items. Over the years, I have taken a 180° turn. Now I’m a huge believer in vocal “warm-ups.” Our volunteer choir has been enjoying this wonderful warm-up exercise […]

President’s Corner

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its 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.

    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.

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.

    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 eminent theologian Suarez (who died in 1617) […] took the position that a pope would be schismatic “if he, as is his duty, would not be in full communion with the body of the Church as, for example, if he were to excommunicate the entire Church, or if he were to change all the liturgical rites of the Church that have been upheld by apostolic tradition.”

— Monsignor Klaus Gamber (1981)
