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.”

Angelus Bells and the Raspberry Pi

Veronica Brandt · January 23, 2016

Raspberry Pi with Speaker RASPBERRY PI is a small, cheap, British computer. Consisting of a credit card sized motherboard with usb ports, hdmi output, headphone jack and micro usb powered, it is a hobbyist’s delight with many, many possibilities. I’ll put the link to more about this fantastic gadget at the end of this article – don’t jump there yet though! I want to show you what I put together first.

I use mine as a little webserver that can be left on all the time as it is silent and doesn’t use much electricity. That’s why you can see the Wi-Pi dongle in the photo, but it’s not integral to this project.

Today I decided to use it to ring a bell for the Angelus three times a day. We are in the habit of saying the Angelus at noon, but 6am and 6pm are harder to remember.

First thing was to settle on a good chime. Searching for Carillon recordings I did find this collection, but they were all too ornate for a simple Angelus bell.

Another handy gadget I have is a midi controller. Using some synthesizer software called Grand Orgue and a sampled Carillon I was able to generate these short recordings:

    * *   The beginning of the Gregorian antiphon Ave Maria

    * *   The beginning of Sub Tuum Praesidium

Then to get the computer to run these I used a feature of most Linux/Unix systems called cron and a program called mpg123 – a command line mp3 player. There is probably a way to do something similar on other computers or even mobile devices.

These might also make great ring tones!

In the meantime, you may like to read more about the Raspberry Pi.

UPDATE: More recordings from Cologne and France

    Why A “Fugue” Here?
    I believe I know why this plainsong harmonizer created a tiny fugue as the INTRODUCTION to his accompaniment. Take a look (PDF) and tell me your thoughts about what he did on the feast of the Flight of Our Lord Jesus Christ into Egypt (17 February). And now I must go because “tempus fugit” as they say!

    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.

    “Reminder” — Month of October (2025)
    Those who don’t sign up for our free EMAIL NEWSLETTER miss important notifications. Last week, for example, I sent a message about this job opening for a music director paying $65,000 per year plus benefits (plus weddings & funerals). Notice the job description says: “our vision for sacred music is to move from singing at Mass to truly singing the Mass wherein … especially the propers, ordinaries, and dialogues are given their proper place.” Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

Quick Thoughts

    “American Catholic Hymnal” (1991)
    The American Catholic Hymnal, with IMPRIMATUR granted (25 April 1991) by the Archdiocese of Chicago, is like a compendium of every horrible idea from the 1980s. Imagine being forced to stand all through Communion (even afterwards) when those self-same ‘enlightened’ liturgists moved the SEQUENCE before the Alleluia to make sure congregations wouldn’t have to stand during it. (Even worse, everything about the SEQUENCE—including its name—means it should follow the Alleluia.) And imagine endlessly repeating “Alleluia” during Holy Communion at every single Mass. It was all part of an effort to convince people that Holy Communion was historically a procession (which it wasn’t).

    “Canonic” • Ralph Vaughan Williams
    Fifty years ago, Dr. Theodore Marier made available this clever arrangement (PDF) of “Come down, O love divine” by P. R. Dietterich. The melody was composed in 1906 by Ralph Vaughan Williams (d. 1958) and named in honor of of his birthplace: DOWN AMPNEY. The arrangement isn’t a strict canon, but it does remind one of a canon since the pipe organ employs “points of imitation.” The melody and text are #709 in the Brébeuf Catholic Hymnal.
    —Jeff Ostrowski
    Did they simplify these hymn harmonies?
    Choirs love to sing the famous & splendid tune called “INNSBRUCK.” Looking through a (Roman Catholic) German hymnal printed in 1952, I discovered what appears to be a simplified version of that hymn. In other words, their harmonization is much less complex than the version found in the Saint Jean de Brébeuf Hymnal (which is suitable for singing by SATB choir). Please download their 1952 harmonization (PDF) and let me know your thoughts. I really like the groovy Germanic INTRODUCTION they added.

Random Quote

Bishops have a duty towards both wise and foolish. They have to rouse the devotion of the carnal people with material ornament, since they are incapable of spiritual things.
