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

Quick Thoughts

16 May 2022 • Harmonized Chant?

This year’s upcoming Sacred Music Symposium will demonstrate several ways to sing the CREDO at Mass. This is because—for many parishes—to sing a full-length polyphonic CREDO by Victoria or Palestrina is out of the question. Therefore, we show options that are halfway between plainsong and polyphony. You can hear my choir rehearsing a section that sounds like harmonized plainsong.

14 May 2022 • “Pure” Vatican Edition

As readers know, my choir has been singing from the “pure” Editio Vaticana. That is to say, the official rhythm which—technically—is the only rhythm allowed by the Church. I haven’t figured out how I want the scores to look, so in the meantime we’ve been using temporary scores that look like this. Stay tuned!

14 May 2022 • Gorgeous Book

If there is a more beautiful book than Abbat Pothier’s 1888 Processionale Monasticum, I don’t know what it might be. This gorgeous tome was today added to the Saint John Lalande Online Library. I wish I owned a physical copy.

Random Quote

“Naturally the accompaniment of the organ is merely tolerated during the office of the dead, but in fact, in nearly every parish this toleration has become a habit.”

— Henri Potiron, 1958
