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:

Please let me know your thoughts about parallel fourths in the Facebook combox. Thanks!

President’s Corner

    Luis Martínez Must Go!
    Sevilla Cathedral (entry dated 13 December 1564): The chapter orders Luis Martínez, a cathedral chaplain, to stay away from the choirbook-stand when the rest of the singers gather around it to sing polyphony—the reason being that “he throws the others out of tune.” [Excerpt from “The Life of Father Francisco Guerrero.”]

    “Booklet of Eucharistic Hymns” (16 pages)
    I was asked to create a booklet for my parish to use during our CORPUS CHRISTI PROCESSION on 22 June 2025. Would you be willing to look over the DRAFT BOOKLET (16 pages) I came up with? I tried to include a variety of hymns: some have a refrain; some are in major, others in minor; some are metered, others are plainsong; some are in Spanish, some are in Latin, but most are in English. Normally, we’d use the Brébeuf Hymnal—but we can’t risk having our congregation carry those heavy books all over the city to various churches.

Quick Thoughts

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

Random Quote

“From the responses received, it is thus clear that by far the greater number of bishops feel that the present discipline [Communion on the tongue and not in the hand] should not be changed at all—indeed, that if it were changed, this would be offensive to the sensibility and spiritual appreciation of these bishops and of most of the faithful.”

— Sacred Congregation for Divine Worship (29 May 1969)
