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.”

Jeff Ostrowski Attempts to Sing the Easter Introit

Jeff Ostrowski · March 15, 2024

ESTERDAY AFTERNOON, I attempted to sing (and accompany) the ancient INTROIT for Easter Sunday. You can listen to my attempt below. I opted for the Church’s official rhythm, choosing the pipe organ accompaniment by the LEMMENSINSTITUUT. It’s utterly miraculous how we can trace CARMEN GREGORIANUM (Gregorian Chant) going back 1,300 years. For example, here’s how this same INTROIT—“Resurréxi Et Adhuc Tecum Sum”—appeared in a manuscript created sometime during the 1300s:

—Easter Sunday’s INTROIT in a manuscript created circa 1393AD.

Here’s the direct URL link.

Ancient Music • The Easter Sunday Propria Missae constitute some of the most ancient music we possess. The official edition (“EDITIO VATICANA”) took into consideration the entire Gregorian tradition—not just a handful of manuscripts—and from that tradition created a CENTO. If I live to be 100 years old, I’ll never understand why some singers select a particular manuscript (such as 121einsie|961) and try to apply that manuscript’s groupings or rhythm to the official edition, which is a CENTO. That would be similar to taking pedal markings from a piece by Franz Liszt and applying them (!) to a piece by Johannes Brahms. In other words, the EDITIO VATICANA by its very nature will be similar but not identical to any single manuscript.

Here’s how the Introit from Easter Sunday looked in Yrieix|1040, written (perhaps) circa 1040AD:

I Reject This! (1 of 2) • There are some who claim that all manuscripts after 980AD are worthless from a rhythmic point of view. Even a priceless and magnificent manuscript such as Yrieix|1040 (in their view) is essentially garbage, because it doesn’t correspond to a handful of manuscripts for which they have a predilection. I don’t wish to begin that argument all over again. I would simply say that I reject the notion that we should “toss out” or “consider worthless” “treat as garbage” 98% of ancient manuscripts from the ‘Golden Age’ of CARMEN GREGORIANUM just because certain people feel a strong predilection for 2-3 manuscripts. I don’t think that makes any sense.

I Reject This! (2 of 2) • I’m absolutely convinced that if a dramatic change in rhythm took place around the year 1,000AD we would have evidence of such a change. Moreover, there was no Internet in those days. Nor did telephones exist. Nor did automobiles exist. Nor did airplanes exist. Therefore, even if somebody woke up one morning and decided to dramatically modify (!) the rhythm of Gregorian Chant, it would not have been possible to notify all the other monasteries (in all the other countries). Furthermore, I believe many monasteries would have forcefully rejected such a proposal, choosing to continue singing plainsong the same way—broadly speaking—they always had. Indeed, with each passing day more manuscripts are added (thanks to the Internet) and each one is a like a slow and uncompromising death knell for anyone arguing a dramatic and universal (!) rhythmic change somehow took place circa 1,000AD.

Moslem Music? • When it comes to ancient music that we can know with certainty CARMEN GREGORIANUM (“Gregorian Chant”) is far and away the oldest. If somebody tells you Jewish music is more ancient than Gregorian chant, they’ve been deceived. If somebody tells you that Muslim music is more ancient than Gregorian chant, they’re not telling you the truth. The reason for this seeming contradiction is simple: Roman Catholics figured out how to write down music long before anybody else. We know the ancient Greeks had music, but we have no reliable understanding of it (because Catholics were the first to figure out how to accurately notate music). We know the ancient Jews had music, but we have no credible notation for it (because Catholics were the first to figure out how to accurately notate music). We know that ancient Moslems sang, but we have no contemporaneous documentation for it (because Catholics were the first to figure out how to accurately notate music). On the Internet, you can find gullible singers who try to make Gregorian Chant sound “more authentic” by imitating the way Muslims or Jews—in the year 2024—sing. This is the equivalent of musicological malpractice. Make no mistake about it: Gregorian Chant is the earliest music we can know with certainty.

Here’s the text from Easter Sunday’s INTROIT in Latin:

Resurréxi, et adhuc tecum sum, allelúia: posuísti super me manum tuam, allelúia: mirábilis facta est sciéntia tua, allelúia, allelúia. Vs. Dómine, probásti me et cognovísti me: tu cognovísti sessiónem meam et resurrectiónem meam. Vs. Glória Patri, et Fílio, et Spirítui Sancto. Sicut erat in princípio, et nunc, et semper, et in sǽcula sæculórum. Amen. Resurréxi, et adhuc tecum sum, allelúia: posuísti super me manum tuam, allelúia: mirábilis facta est sciéntia tua, allelúia, allelúia.

Here’s the text from Easter Sunday’s INTROIT in English:

I arose, and am still with Thee, alleluia; Thou hast laid Thy hand upon me, alleluia; Thy knowledge is become wonderful, alleluia, alleluia. Vs. Lord, Thou hast searched Me and known Me; Thou knowest my sitting down and My rising up. Vs. Glory be to the Father, and to the Son, and to the Holy Ghost. As it was in the beginning, is now, and ever shall be, world without end. Amen. I arose, and am still with Thee, alleluia; Thou hast laid Thy hand upon me, alleluia; Thy knowledge is become wonderful, alleluia, alleluia.

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”
    —Jeff Ostrowski
    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

Random Quote

The literal translation: “Lord, have mercy—Christ, have mercy,” does not offer much material for an acceptable song text. The words, not having any feminine syllables, are abrupt; the sounds are almost all muted and colorless; the rhythmic flow is too brief. So many people may prefer responses that further extend the song of the assembly, e.g., “Have pity on us, Lord” or “Pardon us and change our hearts.

— J. Gelineau attacking the KYRIE ELEYSON (page 64 in “Learning to Celebrate,” 1985)
