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.)

    “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.

    PDF • “Communion” (5th Sunday in Ordin.)
    The COMMUNION ANTIPHON for this coming Sunday, 8 February 2026—which is the 5th Sunday in Ordinary Time (Year A)—is truly delightful. You can download the musical score completely free of charge. This text will be familiar to altar boys, because it’s PSALM 42. The Feder Missal makes the following claim about that psalm: “A hymn of a temple musician from Jerusalem: he is an exile in a heathen land, and he longs for the holy city and his ministry in the Temple there. The Church makes his words her own.”

    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

“These French offices represent a new case of the old tendency towards local modification—which the Council of Trent had meant to repress. They are commonly attributed to Gallican ideas and are supposed to be not free from Jansenist venom. Some of these local French uses survived almost to our own time. They were supplanted by the Roman books in the 19th century, chiefly by the exertions of Dom Prosper Guéranger (d. 1875).”

— Dr. Adrian Fortescue (d. 1923)
