No Greater Advent Piece Exists

Jeff Ostrowski · September 3, 2016

ES, IT’S ONCE AGAIN TIME to start thinking about Advent! We begin with a splendid Advent hymn: Creátor alme síderum. The original title was Cónditor alme síderum, but four Jesuits working for Pope Urban VIII (d. 1644) wrecked most of the Breviary hymns—causing endless confusion. Correct accentuation is crucial since CÓNDITOR means “maker” whereas CONDÍTOR means “pickler.”

The famous tune can be played on this Woofer Guitar:

Before you listen to the full version by Guerrero, explore the Tenor and Soprano only:

Do you see the beautiful counterpoint with just two voices? In real life, one hears clearly the different vocal sections, and the counterpoint sounds awesome. In a YouTube version, however, the voices sound “flattened.”

I couldn’t resist recording it, even though my voice singing all the parts never sounds quite right:

The reason I couldn’t resist is because this composition is so powerful. It’s not even music anymore … Guerrero has here created a force of nature.

By the way, the tempo could probably be slightly slower, but I don’t recommend taking it so slowly that the plainsong in the Soprano line becomes difficult to recognize.

‘Sarum’ Good Friday?

Plainsong of the Roman Rite has many variants—i.e. slight ‘variations’ or ‘alterations’ made to the ancient melodies. Variants often thrive in particular religious orders. Likewise, before Henry VIII broke away from the Catholic Church, Gregorian Chant variants were frequently associated with individual cathedrals in England: Hereford, Lincoln, Salisbury, and so forth. In the early 20th century, the (Anglican) organist at Westminster Abbey married “Let All Mortal Flesh Keep Silence” to this beautiful variant melody from England. Those who sing Gregorian Chant on Good Friday will recognize the melody. What do you think of this pairing?

PDF Download • “Eb Organ Postlude”

Gustav Adolf Merkel (d. 1885) was a German organist, teacher, and composer. Although a Lutheran himself, he held the appointment at the (Roman Catholic) Cathedral of Dresden from 1864 until his death. You can download his Organ Postlude in E-Flat, which I like very much. He has an interesting way of marking the pedal notes. What do you think?

Music List • (Palm Sunday, 2026)

Readers have expressed interest in seeing the ORDER OF MUSIC I created for Palm Sunday—a.k.a. “Dominica in palmis de Passione Domini”—which is 29 March 2026. Please feel free to download it as a PDF file if such a thing interests you. The OFFERTORY (Impropérium exspectávit cor meum) is quite moving. Even though the COMMUNION ANTIPHON is relatively simple, the Fauxbourdon makes it sound outstanding.

“Gregorian Chant Quiz” • 24 March 2026

How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

PDF Download • “Ubi Caritas” (SATB)

I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

PDF Download • “Holy, Holy, Holy”

For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.
