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.”

Misereris omnium | Ash Wednesday Introit

Richard J. Clark · March 5, 2014

EW PARISHES ARE WILLING to sing Gregorian Introits for the Entrance procession. A growing practice is to sing the Introit followed by a hymn. If even this is too much, one may want to sing the Introit as a prelude. This practice allows the faithful to be exposed to the prayerful power of Gregorian Chant when singing the propers is not feasible. Furthermore, this is an excellent opportunity to engage the congregation more deeply and frequently with these transformative texts and chants.

For example, one can seize this opportunity on Ash Wednesday when the pews are filled with many who do not attend mass regularly. It is significant that the very first Introit of Lent sings of God’s infinite mercy: “Your mercy extends to all things, O Lord, and you despise none of the things you have made. You overlook our sins for the sake of repentance. You grant them your pardon, because you are the Lord our God.” —Wisdom 11:24-25, 27; Psalm 57 (56)

PDF • Misereris omnium | Introit | Ash Wednesday

N THIS RECORDING of Misereris omnium, the antiphon is followed by organ variations. The transformation and variety of colors in the organ indicate that through the Lenten season, we do not end up in the same place that we started. Beginning with the thick and rich clarinet stop in the tenor, the piece explores many colors, ending with very light 4’ flutes, in anticipation of Christ’s resurrection.


DESPITE BEING AN ORGANIST with a wonderful instrument at my disposal, I tend to not play instrumental preludes or postludes during Lent with the exception of Laetare Sunday. As such, I find the sung preludes to be effective and even popular as a way of preparing the congregation for prayer, which is the intention of a prelude after all. (That being said, I cannot help but to compose organ variations on this wonderful chant.)

    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’.

    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.”

    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

“It is the choir that can make the most valuable contribution to the liturgy; it is through the choir that significant numbers of the congregation can make a significant and valuable offering in the community’s act of worship. The choir links directly academic excellence, artistic creation, disciplined attention and self expression in the making of something fitting for the worship of God.”

— Father Daniel Higgins, Choirmaster at Saint Edmund’s College, Ware
