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.”

    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.

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

These prayers were not peculiar to Good Friday in the early ages (they were said on Spy Wednesday as late as the eighth century); their retention here, it is thought, was inspired by the idea that the Church should pray for all classes of men on the day that Christ died for all. Duchesne is of opinion that the “Oremus” now said in every Mass before the Offertory—which is not a prayer—remains to show where this old series of prayers was once said in all Masses.

— Catholic Encyclopedia (1909)
