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.”

Jeff Ostrowski · January 31, 2023

OLIEST PRIEST you ever met? That’s a tough question, but one of the holiest was certainly Father Valentine Young (d. 2020). I remember Father Valentine once said: “Jeff, I’ve reached a point in my life where I almost enjoy hearing accompanied plainsong more than unaccompanied.” That statement was two decades ago. At that point in my life, such a statement constituted formal heresy. You see, I used to believe the only ‘valid’ way to sing Gregorian Chant was a cappella (“without accompaniment”). But after almost three decades of singing plainsong, I have come to realize that a well-written accompaniment can add great beauty.1 The following is a recording from last Sunday. You will notice I accompanied our volunteer choir using the NOH harmonies:

Rare Belgian Book • Corpus Christi Watershed has obtained an extremely rare book of organ accompaniments for Belgium. Readers probably know that each country has special feasts, often celebrating local saints. Interesting items abound in this book. For instance, they wrote an accompaniment for the enormously lengthy SEQUENCE for Saint Lambert of Maastricht (Bishop and Martyr). They wrote an accompaniment for the famous “Gaudeámus” Introit—for the feast of Saint Rumbold of Mechlin—which organists will which to compare with the other “Gaudeámus” harmonizations the LEMMENSINSTITUUT provided in the other volumes.

*  PDF Download • VOLUME VI (“Propers for Belgium”)
—Vol. 6 contains “special propers for the dioceses of Belgium” • 129 pages.

Upcoming Presentation • During this year’s Sacred Music Symposium—which will take place in June of 2023—I will be giving a presentation which will demonstrate (using multiple examples) that excellent Gregorian accompaniments employ the self-same techniques used by the great composers. Monsignor Jules Van Nuffel once wrote:

“A flawless harmonization of Gregorian chant cannot be created by improvisation, no matter the competence and ability of the organist or harmonist.”

Please Help Us • We desire to provide professional and pristine scans for other volumes of the NOH, especially VOLUME V, which contains the Ordinary of the Mass. But professional scans cost a lot of money. We’re a tiny 501(c)3 public charity. We exist solely by the generosity of small donors. We have no endowment; we have no major donors; we run no advertisements; we have no savings. We beg you to consider donating $5.00 per month, or even $3.00 per month.

1 So much depends upon the choir, the acoustic, and each situation. For instance, if I am singing the Requiem Mass with superb singers, I would be annoyed if somebody tried to add an accompaniment to our singing.

    “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

What earlier generations held as sacred, remains sacred and great for us too, and it cannot be all of a sudden entirely forbidden or even considered harmful.
