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.”

“Entrance Chant” for Sunday (27-Oct-2024)

This one was put in a “brighter” mode—owing to its text—based on the somewhat peculiar place the original came from.

Music List • (29th Sund. Ordinary Time)

Readers have expressed interest in looking over the “music list” I’ve prepared for this coming Sunday.

Released! • Stellar Hymn We Just Recorded

The Tenor line is particularly pleasant, the way it rises with stepwise motion and then descends.

“Entrance Chant” • For Sunday (20-Oct-2024)

This one’s in Mode 3, imitating the authentic Gregorian chant.

“In Feriis Per Annum” • Kýrie Eléison

For years I’d been meaning to harmonize the famous KYRIE SIMPLEX—but I never got the opportunity until today. Feel free to download the PDF score if you wish. It is “Kyrie XVI,” which in the old books bore the title In Feriis Per Annum.

MONTH OF OCTOBER — “Reminder”

Since a new month has arrived, it’s my pleasure to remind you that…

Rhyme Scheme?

Is this a common ‘thing’ when it comes to hymns in Spanish?

Jeff Ostrowski · October 1, 2024

“Entrance Chant” • For Sunday (6-Oct-2024)

This one’s in Mode 4, imitating in an admirable way the authentic Gregorian chant.

An Anglican “Mess”

If I live to be 100 years old, there’s something I’ll never understand.

    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!

    “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.

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.

Random Quote

Using the shoddiest, sleaziest material we have for the purpose of glorifying God is not very sound theology or even very good common sense. […] (In general, when you see a diminished seventh chord in a hymn, run.) And these chords are usually used in bad hymns in precisely the same order in which they occur in “Sweet Adeline.”

— Paul Hume (1956)
