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.”

“Agincourt” • Do You Know This Hymn?

Jeff Ostrowski · December 17, 2019

VERY ORGANIST AND CHOIRMASTER at one point or another has fallen in love with the English hymn tune “Agincourt” (a.k.a. “Deo Gracias”). It was featured in Henry V, a 1944 movie by Sir Laurence Olivier. The Brébeuf harmonies for this piece remind me why I love this book so much—a truly masterful SATB harmonization: original, fresh, yet within reach. I especially love how the Bass Line walks in stepwise motion…sometimes a whole octave!  If you follow the link below (#536) and click “Bass,” you can see what I mean.

The Tenor line is quite challenging to sing correctly:

Important Notice:

You can hear individual voice tracks if you visit the Brébeuf website; scroll to #536.

HEN I WAS AT THE CONSERVATORY, I had to memorize difficult works by Chopin, Mozart, Bach, Prokofiev, Schumann, and others. Yet, I was nothing compared to some of the students there. Indeed, I would not have dared attempt certain pieces, such as Liszt’s Feux Follets, or Chopin’s Op. 26 No. 6 Etude. Often, I would discuss interpretations with the other students. One girl from China—I can’t recall her name, but she was excellent—had studied with Ruth Slenczynska. I was discussing certain ideas I had about Chopin’s Ballade in Ab Major, and I insisted my interpretation was the correct one. Then she made a comment that haunts me to this day: “Jeff, having ideas is one thing; executing them is something else.”

On the one hand, it is good to have dreams and aspirations. On the other hand, we must face reality. AGINCOURT is a good example. A choirmaster quickly learns this is not an easy piece to sing well with a congregation. Therefore, it must be approached with caution. We may desire to do this piece. We may desire it greatly. Yet, we must never fail to ask: “How did it sound? Did it work?”  By the way, here’s how AGINCOURT looked in the 1936 “English Hymnal,” edited by Ralph Vaughan Williams (d. 1958), a student of Maurice Ravel (d. 1937):

    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!

    “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.

    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

“If he converses with the learned and judicious, he delights in their talent—if with the ignorant and foolish, he enjoys their stupidity. He is not even offended by professional jesters. With a wonderful dexterity he accommodates himself to every disposition. As a rule, in talking with women (even with his own wife) he is full of jokes and banter.”

— ‘Erasmus on St. Thomas More (England’s 1st lay Chancellor)’
