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.”

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st 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 outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.
    —Jeff Ostrowski
    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!

    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

The 1960s reformers had no chance of success since their goal was “recasting from top to bottom—and in a few months!—an entire liturgy which had required twenty centuries to develop.”

— Professor Louis Bouyer, close friend of Pope Saint Paul VI
