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.

President’s Corner

    Luis Martínez Must Go!
    Sevilla Cathedral (entry dated 13 December 1564): The chapter orders Luis Martínez, a cathedral chaplain, to stay away from the choirbook-stand when the rest of the singers gather around it to sing polyphony—the reason being that “he throws the others out of tune.” [Excerpt from “The Life of Father Francisco Guerrero.”]

    “Booklet of Eucharistic Hymns” (16 pages)
    I was asked to create a booklet for my parish to use during our CORPUS CHRISTI PROCESSION on 22 June 2025. Would you be willing to look over the DRAFT BOOKLET (16 pages) I came up with? I tried to include a variety of hymns: some have a refrain; some are in major, others in minor; some are metered, others are plainsong; some are in Spanish, some are in Latin, but most are in English. Normally, we’d use the Brébeuf Hymnal—but we can’t risk having our congregation carry those heavy books all over the city to various churches.

Quick Thoughts

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

Random Quote

The effectiveness of liturgy does not lie in experimenting with rites and altering them over and over, nor in a continuous reductionism, but solely in entering more deeply into the word of God and the mystery being celebrated. It is the presence of these two that authenticates the Church’s rites, not what some priest decides, indulging his own preferences.

— Liturgicae Instaurationes (1970)
