What Palestrina Did With Kyrie II (“Fons Bonitatis”)

Jeff Ostrowski · January 15, 2020

AGNIFICENT! There is no other word for it. I am speaking of the Palestrina’s Kyrie based on the Gregorian Kyrie II (“Fons Bonitatis”), which is divided—as you might guess—into three marvelous sections. You can listen all three sections by visiting Lalemant Polyphonic and scrolling to 81668. I strongly encourage you to do this!  And just where does “Kyrie Fons Bonitatis” come from?  We remember that prior to the Council of Trent, the prayers at Mass were “troped.” Many erroneously believe the Kyrie was the only thing troped, but that’s not even close to true. The Gloria, Sanctus, Agnus Dei—and even the readings!—were troped.

Here’s a rehearsal video we made for Part 1 of 3. (I again humbly request that you go listen to the other sections, as well.)


Kyrie II (“Fons Bonitatis”) has remained remarkably stable. Look how it appeared in Cantus Varii, a marvelous collection by Solesmes printed in 1928:

A 2011 publication from Germany seemingly copied this 1928 edition without any changes, although it inserted “tropeless” Editio Vaticana repetitions which puzzle me:

A 2016 publication with variations from the Sarum Use also seemingly copied the 1928 version verbatim, with a few very minor changes (e.g. Pneumáte instead of Pnéumatis):

In the most wonderful way, Palestrina derives his polyphonic lines from the complicated chant melodies of Kyrie II.  For example:

HENEVER POSSIBLE, we must locate the version (“variant”) of the plainsong which Palestrina was looking at when he wrote his Mass. But which version was it? This question is sometimes impossible to answer because we know so little about the lives of the Renaissance composers. However, as I mentioned earlier, Kyrie II is relatively “stable” compared to other chants, so we can be fairly certain the version Palestrina had before him is similar to what we have in the Editio Vaticana.

Consider this version from the 14th century:

 

Here’s one from the late 15th century:

80360-Palestrina-Kyrie-Fons-Bonitatis-late-15th-century

 

Another version from the 15th century:

 

A version from 1525AD:

 

Here is a version from 1580AD:

 

A version from 1591AD:

 

Here is a version from the 16th century:

 

Another from the 16th century:

 

Here’s the version Dr. Peter Wagner chose in his 1903 Kyriale:

80359-Peter-Wagner-Gregorian-Kyrie-ii-edit

 

And here’s the version Mocquereau chose for his 1903 Liber Usualis. Notice the spots where it differs from Pothier’s Editio Vaticana:

80358-1904-Mocquereau-LIBER-USUALIS

Here is the 1863 edition by Father Hermesdorff, the teacher of Peter Wagner (considered a “corrupt” edition of plainsong):

 

 

Here is another “corrupt” version of Kyrie II printed in 1857:

 

The particular way Palestrina places the chant melodies from Kyrie II into his version is stunning. I was going to say Part 3 was my favorite, but Part 2 is also magnificent—and so is Part 1. So it’s all my favorite! The rehearsal videos we made simply don’t do justice to this masterpiece.

In grad school I remember thinking Palestrina wasn’t as interesting as certain other composers; but I was dead wrong.

By the way, here is a (pretty terrible) organ accompaniment for “Kyrie Fons Bonitatis” by Dr. Auguste Le Guennant (d. 1972)

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).
