Lesson 2: Intervallic Relationships

I’ve already mentioned that songs can begin on any pitch, but the intervallic relationships must not be changed. Let us now explore these intervallic relationships.

We usually use “solfege” (Do Re Mi Fa Sol La Ti Do) to help us learn these intervallic relationships. Instead of solfege, the French often use numbers (1 2 3 4 5 6 7 8). Either system is fine:

You probably noticed there isn’t quite as much space between two steps: MI-FA and TI-DO. This is because MI-FA and TI-DO are “half steps.” All the other steps (for instance, DO-RE) are “whole steps.” It is absolutely essential (and I cannot stress this enough) that you memorize MI-FA and TI-DO as being half steps. In the following video, I start on four different starting pitches, and then (always keeping the intervallic relationships inviolable) go up the first four notes. See if you can hear that MI-FA (the half step) is not as wide an interval as the other steps:

In the next video, I demonstrate the aural difference between an ascending half step and an ascending whole step. I could have chosen any ascending whole step (e.g. SOL-LA) or any ascending half step (e.g. TI-DO), but I chose DO-RE and MI-FA:

In the next video, I show the demonstrate difference between a descending half step and a descending whole step. I could have used any descending whole step (e.g. MI-RE) or descending half step (e.g. FA-MI), but I chose LA-SOL and DO-TI:

According to the MISSALE RECENS, the Feast of Saint Gregory the Great occurs on 3 September (the date Gregory became pope). Formerly, his feast was celebrated during Lent, on 12 March (the day Gregory died). In Latin, the feast is: Die 3 Septembris: S. Gregorii Magni, papæ et Ecclesiæ doctoris. you can download the Latin Introit, the Latin Offertory, as well as the Communion with gorgeous fauxbordon in English. Abbat Joseph Pothier—along with Dom André Mocquereau, Bishop Laurent Janssens, Father De Santi, and other Gregorian superstars—sang with a choir of 1,210 voices (from 36 different Roman colleges) under the direction of Monsignor Antonio Rella. That Mass included the “Alma cohors,” a special SEQUENCE for Saint Gregory…much to the dismay of those who believe in strict adherence to rubrics. The Mass on 11 April 1904 was celebrated by Pope Saint Pius X, at the great GREGORIAN CONGRESS held in Rome “to mark the 13th Centenary of the death of Saint Gregory the Great.” Someday, there’s much I’d love to say about this congress. We even have recordings (!) from it (made in 1904 by the Gramophone Company) with choirs conducted by Dom Pothier, Dom Mocquereau, Dom Janssens, Monsignor Rella, Baron Kanzler, and others.

New Bulletin Article • “7 September 2025”

My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article is called: “Professor Bouyer’s Regret.”

Cardinal Ranjith on “Active Participation”

From 2005–2009, Malcolm Cardinal Ranjith served as Secretary of the Congregation for Divine Worship and the Discipline of the Sacraments. He was considered ‘papabile’ during the last conclave. On 8 December 2008, he wrote this powerful statement concerning Gregorian Chant, participatio actuosa, celebration “ad orientem,” and other subjects. When it comes to the question of what “sacred” means, Monsignor Robert A. Skeris provides a marvelous answer.

Solemn “Salve Regina” (Chant)

How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

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.
