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.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

Random Quote

After ordering the bishops to appoint in each diocese “special commission of persons who are really competent in the matter, to whom they will entrust the duty of watching over the music performed in the churches in whatever way may seem most advisable,” Pope Pius X continues—“this commission will insist on the music being not only good in itself, but also proportionate to the capacity of the singers, so that it may be always well executed.”
