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.”

President’s Corner

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.
    —Jeff Ostrowski
    PDF Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

Quick Thoughts

    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

The People’s Hymnal suffers from a too literal and awkward translation. And even in the lovely Slovak “Memorare” in The Saint Gregory Hymnal we are still asked to sing “that anyone who sought thee, or made to thee his moan.” Why not “groan” or “bone” or even “phone?” The only thing necessary, it seems, is that it rhyme with “known.”

— Mons. Francis P. Schmitt (1958)
