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.”

Palestrina • Jaw-Dropping “Kyrie” based on a Hymn

Jeff Ostrowski · October 18, 2016

AST FRIDAY, I MENTIONED how the complete works of Palestrina can be downloaded in PDF format, but the clefs are archaic. I promised to show what can be done with these scores and today I fulfill my promise. They can quickly be placed into SIBELIUS, so the archaic clefs are eliminated. 1 Then your singers can more easily enjoy these treasures, many of which have not been sung for centuries! I want to talk about the NAME of this Mass, but first let’s explore:

* *  PDF Download • KYRIE “Te Saeculorum” (Palestrina)

Two generous young ladies—currently in high school—helped me record it:

MARVELOUS REHEARSAL VIDEOS for each individual voice have been created for volunteer choirs. To access them, locate #6995.

WHEN IT CAME TO CHOOSING a name for this Mass, Palestrina ran into a difficulty. There was not in Palestrina’s day—and amazingly still is not—a book which names the Gregorian hymn tunes. Because the text “Jam Christus astra ascenderat” used the melody, he chose that name. However, he could have easily chosen other names, which you can understand by reading the penultimate page of the score (SEE ABOVE). Throughout history, different melodies have been “married” to hymn texts—and this practice continues even now.

Indeed, Abbot Pothier chose different melodies in 1885 than he would twenty years later for the Editio Vaticana. For example, consider “Jesu Dulcis Memoria” and “Sanctorum Meritis” in this rare and fascinating book of hymns:

* *  PDF • HYMNI DE TEMPORE ET DE SANCTIS (Pothier, 1885)

The choir I direct often sings a spellbinding polyphonic version of “Te Saeculorum Principem,” which is the same hymn melody Palestrina used for his Mass. That’s why I made this clear in the title of my edition, as well as marking the various points where the hymn tune occurs. But this Mass could just have easily been called the “Vexilla Christus” Mass; or the “Te Lucis” Mass; or the “Lucis Creator” Mass. 2 Indeed, it might well be called Missa Ad Coenam Agni. (Notice, by the way, the treatment of hypermetric syllables in that MSS.) Or, for that matter, Missa Lucis Creator. Or, looking at a hymnal from 1876AD, you could call it Missa Ad Coenam Agni—I give this as yet another example.

While there’s nothing incorrect about calling the Mass JAM CHRISTUS ASTRA ASCENDERAT, doing so might cause some to believe it’s for the Ascension. In fact, the hymn is suitable for Pentecost or the Sundays after Pentecost. If you read the literal translation by Fr. Joseph Connelly, you’ll agree it’s a really cool hymn. Notice where Connelly says, “The hymn stops abruptly, and some MSS tried to remedy this by adding another verse.”

If you think I’m getting worried over nothing, think again! For example, the wikipedia entry wrongly labels as this Mass as “for the Ascension” as you can see:

For the record, Fr. Haberl did something odd with the underlay in the “Christe” section of this KYRIE, inexplicably disrupting a pattern. I tried to “fix” it, but was not 100% successful. 3

759 Palestrina

I hope to transcribe and record more movements. Here is the SANCTUS.

MS D 9, folio 573 [283r] shows two Easter hymn texts with this tune:

330 MS D 9 page 573 [283r]

To completely confuse your mind, look at the tune this hymnal used for “Jam Christus Astra Ascenderat” (1876AD):

This polyphonic Mass is clearly based on the “Jam Christus” hymn melody, but I don’t know the composer:

CORRECTION: Dr. Aaron James pointed out the beginning is similar but this is NOT based on “Jam Christus”—rather, it is a piece by Isaac based on Virgo prudentissima.

But this is certainly Te Saeculorum Principem:

Other hymns that use this tune include JESU REDEMPTOR SAECULI and VENITE SERVI SUPPLICES and HAEC HORA QUAE RESPLENDUIT.


NOTES FROM THIS ARTICLE:

1   Since I know how to read archaic clefs, I just transpose in my head. If you don’t know how to read the clefs, enter them into Sibelius—which does contain such clefs—then copy and paste to modern clefs when you’re finished.

2   That’s because the melody is identical. This reminds me of a heated conversation I once had with a gentleman who insisted that the “1962 Missal” had nothing to do with the “Extraordinary Form,” since that nomenclature wasn’t around in 1962. He failed to understand that some things in life have more than one name.

3   The whole issue of text underlay is quite complicated, and anyone who tells you otherwise hasn’t spent enough time looking through the MSS. Indeed, the printer sometimes changed what the composer wanted, which makes things even more complicated. The text underlay by Guerrero often strikes me as “wrong,” but when we sing his music at Mass, suddenly it seems perfect & clever. I’ve come to believe that frequently there is no “absolutely correct” text underlay—in other words, I now have a more relaxed attitude.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

    “Rare Photographs” • Hannibal Bugnini
    On 2 September 2025, we included in this article extremely rare photographs of Archbishop Hannibal Bugnini taken in Iran circa 1979. Bugnini had initially been banished by the pope to Uruguay, but he refused to obey. [This is interesting, since Bugnini relied upon ‘blind obedience’ when it came to modifications of the ancient liturgy.] After he refused to obey the order from the pope, Hannibal Bugnini was banished to Iran. You can also watch a short video of Hannibal Bugnini in Iran, dated 10 November 1979. That’s about a week after the USA embassy hostage crisis began in Tehran, and Pope Saint John Paul II had sent the leader of the Iranian Revolution a special letter.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

Random Quote

“Been to Catholic church and heard Mass. Execrable music! Organ played by a young girl who made impossible harmonies. Sermon very long. The preacher screamed loud enough to tire his lungs. The congregation was affected.”

— Louis Moreau Gottschalk (8 May 1864)
