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.”

Hidden Gem: Dormi Jesu (Luc Jakobs)

Keven Smith · October 20, 2022

ON’T YOU HATE IT when someone recommends a great Christmas motet to you on December 21? Especially when it’s a brilliant piece that you would have had your choir learn if you had only known about it earlier? You’ll thank me, then, for writing this article in October and introducing you to a Christmas motet your choir will love. It’s a piece you would have found only after many hours of searching on Choral Public Domain Library. Or maybe you would have skipped over it because you haven’t heard of the composer.

Luc Jakobs isn’t a famous name—but based on his spellbinding Dormi Jesu, he should be. According to CPDL, he’s a Dutch composer, choral conductor, and harmony teacher born in 1956.

Inside Dormi Jesu

Mr. Jakobs’ SATB setting of Dormi Jesu uses the standard text. It’s slow and delicate yet colorful. Although Mr. Jakobs provides a key signature of 2/2, I’ve always conducted it in four. We begin in Db major with a tenor solo against sustained notes in the other voices. After eight bars, the sopranos take the melody. We then encounter a middle section in Bb major in which the sopranos hold onto the melody and the alto line splits to create some delicious dissonances. While Mr. Jakobs keeps the dynamics at piano and pianissimo throughout this middle section, the intensity does increase. For the final 12 bars, we return to the tranquility of the motet’s opening, which makes sense because the whole point is to lull our Infant Lord to sleep so that Our Lady can finally get some rest.

What to Look and Listen for

What I love about this piece:

  • It sets a Christmas text that hasn’t been used to death. There are so many settings of O Magnum Mysterium out there. I would never discourage a composer from writing another—in fact, one of my friends recently did just that for our choir. But as a choir director, you hesitate to keep bringing the same text, however beautiful it is, to your choir. Dormi Jesu will give most choirs a fresh text for meditation as they sing.
  • It’s classical enough and “cool” enough to please everyone. Mr. Jakobs uses some distinctly jazzy chords, but he does it under a veil of reverence and awe. Even an avowed enemy of modern harmonies will have to admit that this motet is gorgeous. Meanwhile, for a choir that sings mostly Renaissance polyphony, this piece will present a welcome change of pace.
  • It’s simple in its construction. Notice I didn’t say it was “easy” (more on that below). But it’s the kind of piece that will immediately seem within reach for even a small, advancing choir. Besides the fact that there’s alto divisi, there’s not much here to dissuade choir directors from trying Dormi Jesu.

A few tips:

  • Encourage your singers to listen to the recording frequently. I’ve noticed something about pieces that contain “crunchy,” hard-to-tune chords: the learning usually goes much more quickly than I expect. I suspect that a choir with good listening skills can pick up lines more easily in a colorful piece than they can in a “tame” piece. Perhaps it’s a matter of motivation? Choirs want to sing stunning music. And while I strive never to bring dull music to my choir, I must admit that not every motet makes my singers’ eyes light up. This Dormi Jesu does, every year. If it sounds too difficult for your choir, don’t give up on it until you’ve let them try it. You may be surprised at the results.
  • Listen to beginnings and ends of phrases. This Dormi Jesu is full of little lifts. It would be easy to bask in the luscious chords while letting entrances and cutoffs get ragged. I struggled with “cleanness” in this piece at first, probably because I was trying to do too much as a conductor. Yes, everyone should watch the conductor carefully, but giving constant cutoffs in a piece like this can slow down the line. I’ve found that the real key is to remind everyone to breathe together (and in rhythm) for entrances and to listen for everyone else at phrase endings. I’ll even tell them, “Don’t be the first to cut off….but don’t be the last.” Sometimes vagueness trumps specificity.
  • Move DO. Listening to the recording of Dormi Jesu is helpful, but of course I had my choir polish up this piece with solfege. If you do the same, don’t forget to move DO. The beginning of this piece is clearly in Db major. I had my singers switch to Bb major in bar 16, one bar before the change of key signature, because I think it makes a smoother transition of syllables (for example, the basses are then thinking SOL-DO, which they’ve done thousands of times). My singers then switch to G major in bar 30 to ensure a smooth transition to bar 31, which is just a G major chord other than the tenor. The final change is to Bb major in bar 35.
  • Beware of bar 31. As I mentioned, it’s almost a regular G major chord, but the tenor has an A. This is a tough one to tune because after a couple of key changes, aural fatigue begins to set in. I got good results by having my choir drill that transition from 30 to 31 without tenor and pointing out to them that they’re landing on a regular G major chord. I then warned them not to listen too hard to the tenors when I added them back in. Once choirs know that a “wrong” note belongs there, they can work around it!

When my choir learned this piece several years ago, the composer’s website encouraged choir directors to notify him of any performances. I emailed Mr. Jakobs to let him know we had sung Dormi Jesu at Midnight Mass and received a gracious reply. I hope this motet will become as much of a favorite in your loft as it has been in mine.

    PDF Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    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!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    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.

Random Quote

“I ask that future priests, from their time in the seminary, receive the preparation needed to understand and to celebrate Mass in Latin, and also to use Latin texts and execute Gregorian chant; nor should we forget that the faithful can be taught to recite the more common prayers in Latin, and also to sing parts of the liturgy to Gregorian chant.”
