Views from the Choir Loft

Allowed or Forbidden? • Parallel Fourths in Renaissance Polyphony

Jeff Ostrowski · August 6, 2020

HOSE WHO CLICK on #79075 will find marvelous items. The first is a special “Mode 7” version of the MAGNIFICAT combining versions from Father Guerrero, Father Morales, and Palestrina. (All are seventh mode, so they mix together well.) The score helps singers understand that the Mode 7 plainsong appears in each voice elongated (“in augmentation”) depending upon the movement. (In the live recording below, the final movement is omitted). Not only that, but rehearsal videos for each individual voice are provided at #79075. On top of all that, two (2) YouTube videos containing a discussion about this marvelous “Guerrero+” composition are linked to.

Before Covid-19 hit, our choir was learning this Magnificat. Here’s a recording made during one of our rehearsals:

Disclaimer: The microphones cannot capture the true beauty of choral singing, just as a Postcard cannot capture the true beauty of a sunset.

In the section by Father Cristóbal de Morales, we find parallel fourths. (The same exact thing happens in measures 29-30.) See for yourself:

But are parallel fourths allowed in Renaissance polyphony?

The student of Father Morales was Father Guerrero (who turned out to be an even greater composer than his teacher). In Missa Beata Mater, Father Guerrero uses parallel fourths:

Dr. Mahrt explains the ‘Spoken’ Propers

In 1970, the Church promulgated a new version of the Roman Missal. It goes by various names: Ordinary Form, Novus Ordo, MISSALE RECENS, and so on. If you examine the very first page, you’ll notice that Pope Saint Paul VI explains the meaning of the ‘Spoken Propers’ (which are for Masses without singing). A quote by Dr. William P. Mahrt is also included in that file. The SPOKEN PROPERS—used at Masses without music—are sometimes called The Adalbert Propers, because they were created in 1969 by Father Adalbert Franquesa Garrós, one of Hannibal Bugnini’s closest friends (according to Yves Chiron).

PDF • “Music List” (1st Sunday of Advent)

Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 30 November 2025, which is the 1st Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is quite memorable, and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

“Music List” • Christ the King Sunday

Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 23 November 2025, which is the 34th Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. In the 1970 Missal, this Sunday is known as: Domini Nostri Jesu Christi Universorum Regis (“Solemnity of Our Lord Jesus Christ, King of the Universe”). As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the magnificent feasts website alongside the official texts in Latin.

“Translations Approved for Liturgical Use”

According to the newsletter for USSCB’s Committee on Divine Worship dated September 1996, there are three (3) translations of the Bible which can be used in the sacred liturgy in the United States. You can read this information with your own eyes. It seems the USCCB and also Rome fully approved the so-called NRSV (“New Revised Standard Version”) on 13 November 1991 and 6 April 1992 but this permission was then withdrawn in 1994.

Gospel Options for 2 November (“All Souls”)

We’ve been told some bishops are suppressing the TLM because of “unity.” But is unity truly found in the MISSALE RECENS? For instance, on All Souls (2 November), any of these Gospel readings may be chosen, for any reason (or for no reason at all). The same is true of the Propria Missæ and other readings—there are countless options in the ORDINARY FORM. In other words, no matter which OF parish you attend on 2 November, you’ll almost certainly hear different propers and readings, to say nothing of different ‘styles’ of music. Where is the “unity” in all this? Indeed, the Second Vatican Council solemnly declared: “Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community.”

“Our Father” • Musical Setting?

Looking through a Roman Catholic Hymnal published in 1859 by Father Guido Maria Dreves (d. 1909), I stumbled upon this very beautiful tune (PDF file). I feel it would be absolutely perfect to set the “Our Father” in German to music. Thoughts?
