An Unexplained Problem

Jeff Ostrowski · May 9, 2014

URING THE EASTER VIGIL, after the 7th Reading (when there are no Baptisms) two possible options are given. There is nothing to indicate that one option should be preferred.

Notice that one option is identical to the Responsorial Psalm sung after the 5th Reading:

R. (3) You will draw water joyfully from the springs of salvation.
Is. 12:2-3, 4, 5-6 — God indeed is my savior …

R. (12a) Create a clean heart in me, O God.
Ps. 51:12-13, 14-15, 18-19 — A clean heart create for me, O God …

Music directors often choose the 2nd option to avoid repeating the same Responsorial Psalm that has already been sung after the 5th Reading.

Can anyone explain why the same Responsorial Psalm was assigned after the 5th and 7th readings? I’m not sure there’s another Mass like this. I know that the Offertory & Communion for the 1st Sunday of Lent are practically identical, but the musical setting is completely different.

Any thoughts? Let me know in the combox.

THE ANSWER COMES FROM STEVEN VAN ROODE:

The remarkable thing here is not so much that one of the options given already appeared after the fifth reading, but that the English translation of the Lectionary gets the rubric wrong!

The Latin reads, after listing Ps 41 as the responsorial psalm for the seventh reading: “Vel, quando celebratur Baptisma, Is 12 ut supra (post lectionem n. 5), vel etiam Ps 50…”

So, according to the Latin typical edition, Ps 41 ‘Like a deer’ is always sung after the seventh reading, except when there are Baptisms, when also Is 12 ‘You will draw water’ or Ps 51 ‘Create a clean heart’ may be chosen. The English however reverses the condition to choose the options: “When Baptism is NOT celebrated”!

The reasoning of the Latin rubric makes much more sense to me: when there are Baptisms and the fifth reading wasn’t used (yes, that’s possible), Is 12 can be chosen as responsorial psalm because of its clear Baptism theme. If the fifth reading was used and so Is 12 was already sung, Ps 51 can be chosen, which is also related to Baptism.

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.

PDF Download • “Atténde Dómine”

Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

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.”

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.
