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.”

Does Polyphony “Fit” Ordinary Form Masses?

Jeff Ostrowski · July 11, 2017

URING THE SACRED MUSIC SYMPOSIUM, I described how to painlessly add polyphony to the Ordinary Form by “sneaking it in” with choral extensions. So much information was shared during our conference—from 7:30am until 9:30pm each day, literally—that I wasn’t able to spend sufficient time explaining.

Therefore, I’ve created this video:

REHEARSAL VIDEOS for each individual voice await you at #4884.
As always, the PDF score can be downloaded there, too.

IF YOU DON’T HAVE enough voices to do the example above, consider the following: Guerrero “Iste Sanctus” (#5294); Palestrina Short (#6482); Palestrina Longer (#6995); Guerrero “Beata Mater” (#3347, #3661, #3579); Durieux (#4638); Palestrina “Impleta sunt” (#5053, #5054); Brudieu (#4327).

The Mass setting in the video is from Victoria’s Officium Defunctorum. This is a famous piece, and I was too scared to “vandalize it” by transposing it up a whole step—but my choir will most likely do so. Fr. Victoria’s work is based on the Requiem KYRIE, so I could have chosen the plainsong accordingly, but only if we were singing it for an actual Requiem. Despite what some assert, these are not rigid rules that can’t be changed. For example, most editors choose Mode II for Allegri’s Miserere Mei, but the actual music is based on the Tonus Peregrinus. Indeed, Sanctus VIII was taken verbatim from O Quam Suavis Est; but does that mean Sanctus VIII can only be sung on feasts where that Antiphon is employed? I think not.

I recorded all the voices for the above video except the third section, which was recorded by volunteers at Sacred Music Symposium 2017. Can you hear the difference? Listen closely to the richness in the third section, which begins at the 2:17 marker.

Don’t expect the congregation to understand immediately when they are supposed to sing. It will take at least a year before they begin to understand. At the Symposium, we spoke of the importance of using the same structure every Sunday for a long time before the good fruits become evident. That is why I would never dream of introducing the propers at OF Masses unless the congregation had a book such as the Isaac Jogues Pew Lectionary, which has 100% of the propers in Latin and English. I repeat: it takes years to reintroduce authentic liturgy, because our people have been robbed for half a century.

Quick Thoughts

    What does this mean? “Pre-Urbanite”
    One of the things informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal has to do with its careful treatment of the ancient hymns vs. the “Urbanite” hymns. This topic I had believed to be fairly well understood—but I was wrong. The reason I thought people knew about it is simple; in the EDITIO VATICANA 1908 Graduale Romanum (as well as the 1913 Liber Antiphonarius) both versions are provided, right next to each other. You can see what I mean by examining this PDF file from the Roman Gradual of 1908. Most people still don’t understand that the Urbanite versions were never adopted by any priests or monks who sang the Divine Office each day. Switching would have required a massive amount of effort and money, because all the books would need to be changed.

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

Random Quote

“…it would be a very praiseworthy thing and the correction would be so easy to make that one could accommodate the chant by gradual changes; and through this it would not lose its original form, since it is only through the binding together of many notes put under short syllables that they become long without any good purpose when it would be sufficient to give one note only.”

— Zarlino (1558) anticipating the Medicæa
