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.”

Vespers for Easter Wednesday, Thursday and Friday

Veronica Brandt · March 25, 2023

I HAVE the good fortune to be joining in a Homeschooler Retreat during Easter Week. We have a chaplain from the Priestly Fraternity of St Peter and the prospect of a week full of Sung Masses, Benediction, Rosaries and fun. This year there was a suggestion to add in Sung Vespers, possibly Wednesday, Thursday and/or Friday.

Albert Bloomfield has a huge collection of printables for Vespers and Tenebrae as previously mentioned on this blog. The target Vespers are very much like that for Easter Sunday, which has a 7 page booklet all ready as a PDF. The only thing required was to adjust the last page to change the Magnificat Antiphon, the mode for the Magnificat verses and the Collect.

The easy way would be to make a separate last page, but, as the rest of the booklet was made using LaTeX and Gregorio, I embarked on the task of updating and editing Albert Bloomfield’s gabc-chant Source Code. The project was last updated 9 years ago. Gregorio has changed a lot over those years. Some updates are simple substitutions, but others are more involved and some code is still a bit of a mystery to me.

This is the beauty of Open Source Software. When someone provides access to their work, then it can be preserved, adapted, and built upon. This case may not have saved me much time, but has made a much more handsome booklet and given me a window into a very different way of organizing big gregorio projects.

I have “forked” Albert Bloomfield’s repository, which means I have my own copy which links back to the original repository. Github tracks the changes. As of writing, I have changed 79 files with 8,993 additions and 387 deletions. I think many of those files are the intermediary files1 which I have been too lazy to exclude from the repository. This may have inflated the numbers. It did feel like quite a bit of work though.

  • EasterWedThursFri – this one is basically Easter Sunday with a heading saying “Easter Week” – I’ll use the first 6 pages and then the last page of the following 3 PDFs.
  • EasterWednesday
  • EasterThursday
  • EasterFriday

You may notice I also changed the page dimensions to A4 as US Letter paper is nigh impossible to obtain here in Australia. This is something I love about having access to the source code and being able to adapt existing work. This doesn’t happen very often in the world of sheet music – the Choral Public Domain Library being a notable exception.

A big THANK YOU to everyone who has contributed to this global collaboration making it possible to prepare Gregorian chant scores like this!


NOTES FROM THIS ARTICLE:

1   The software creates auxilliary files each time changes are made. Some examples are filenames ending with .aux, .gtex, .log, .glog, .toc, .ind, .idx. The original repository excludes most of these, but some, like .gtex files were a more recent development.

    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

“As late as 1834, British society had many restrictions on any person not adhering to the Anglican church. For example, Roman Catholics could not attend a university, serve on a city council, be a member of Parliament, serve in the armed forces, or even serve on a jury.”
