Angelus Bells and the Raspberry Pi

Veronica Brandt · January 23, 2016

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

“Daily I sat in the temple, close to you…”

Fulton J. Sheen always said the “very best translation” of Sacred Scripture was the version by Monsignor Ronald Knox, and here’s what Knox had for the Passion read today (Pre-1955 Palm Sunday): “And Jesus said to the multitude at that hour, You have come out to my arrest with swords and clubs, as if I were a robber; and yet I used to sit teaching in the temple close to you, day after day, and you never laid hands on me.” (Mt 26:55)

Did you catch that? Our Lord sat close to them! He was near them! The Second Person of the Blessed Trinity touched them, and was friendly toward them! Truly, the people who can hurt us the most—and betray us the most—are those whom we have loved.

Sacred Music Symposium • “What We Avoid”

I wish we had to time to discuss artwork at the Sacred Music Symposium, but there’s just not enough time. At this year’s conference in June, we will sing an absolutely incredible Magnificat setting by Father Francisco Guerrero (d. 1599). If you examine the part books, you will notice a marvelous aesthetic desire to avoid the same capital letter—for the sake of beauty. Do you see how the Part Books find a way to avoid repeating the Capital G twice, by using the word “Superius” (which is roughly analogous to “Soprano”)? Breathtaking!

“Abraham” • Guerrero Imitates His Teacher

Father Francisco Guerrero (d. 1599) studied music with Father Cristóbal de Morales circa 1545. He taught himself the organ. On 3 April 1542 he was engaged as a contralto by Seville Cathedral at an annual salary of 12,000 maravedís. He remained there until 1546, when, at the age of only 17, he was invited—on the recommendation of Father Morales—to become mæstro de capilla of Jaén Cathedral. He was entrusted with the boarding, lodging, and instruction of the six choirboys; but he neglected this duty and was sentenced to be dismissed on 30 August 1548. However, he was absolved and reinstated on 3 November. I think you can see (perhaps) a little homage to his teacher on the word “Abraham.”
