PDF Download • “Lucis Creator Optime” (Vespers Hymn)

Jeff Ostrowski · January 21, 2020 ·

HEN I PLAY organ for Vespers on Sunday afternoon, sometimes I have to jump in and sing. It doesn’t happen often—because we usually have at least 30-40 singers—but on certain days it’s necessary…such as the Sunday before Thanksgiving, when the attendance was quite sparse! We normally do the “Lucis Creator Optime” to a metrical hymn setting, taken from the Brébeuf Hymnal (since everything else is sung in plainsong) but sometimes we sing the plainsong version.

I composed this organ accompaniment following the “Brébeuf method,” where every verse is written out:

Perhaps my favorite thing about the Saint Jean de Brébeuf Hymnal is how every single verse of the organ accompaniments is carefully written out. It makes life so easy, I actually feel guilty! Notice how the accompaniment provides contrasting accompaniments for the same melodic phrase; one has the bass line in descending stepwise motion, while the other has the bass line in ascending stepwise motion:

But the Brébeuf Hymnal is hardly the first book to recognize how essential it is to write out every verse. Take a look at this special Paris edition of the Antiphonale, printed in 1913:

By the way, the approbation in the front of that book is by Cardinal Martinelli, who wrote a very important letter condemning the “Mocquereau” rhythm, the “Wagner” rhythm, and the “Haberl” rhythm. We shall speak of that letter another day…

I think you’ll agree we have made tremendous progress since 1851, when this accompaniment appeared:

(That is from an 1851 book called “Hymnarium Vesperale.”)

Could Pope St. Pius X Sing?

“On 12 March 1908, the complete publication of the Roman Gradual was issued by the Vatican Press. On that very day, Dom Pothier solemnly presented the first copy to the Holy Father. A witness of the audience says that Pius X wished to be the first to see the new book; he opened it at random, at page 128 of the supplement pro aliquibus locis—it was the Introit of the new Feast of Our Lady of Lourdes. The Pope sang it with perfect taste to the last note.” (Catholic Choirmaster, February 1915)

Julius Bas Accompaniment

A very prolific harmonizer of Gregorian chant in the early 20th century was Mr. Julius Bas. He often uses a very strange technique, wherein he employs rests to eliminate the Alto, Tenor, and Bass voices. Consider what he did with “Lumen ad revelationem” here:

It seems quite lazy, and I’ve never seen anyone else use such a technique, although Dr. Peter Wagner often switched to parallel octaves when he ran out of ideas… (Yuck!)

Hitting wrong notes

Fr. Valentine Young, OFM, used to say: “The organist can play 1,000 correct notes and one wrong note—and the only thing people will care about is the wrong note.” Last Sunday I hit some wrong notes, and felt bad. Then I remembered a story about Rudolf Serkin and started to chuckle. Charles Rosen (or was it Leon Fleisher?) told the story of Serkin playing a Beethoven Sonata in front of a large audience. The theme is all in octaves; but Serkin hit some wrong notes, and played parallel 7ths instead. This so unnerved him that every time the theme returned, he played the entire thing in parallel 7ths! We must remember that even the greatest hit wrong notes. Alfred Cortot, Vladimir Horowitz, Wilhelm Backhaus, Edwin Fischer, Sviatoslav Richter, Egon Petri—they all hit wrong notes, which we can hear on recordings. (Josef Hofmann was an exception, but he was super-human so he doesn’t count!)
