“How Do I Use Gregorio? How Do I Use GABC?”

To prove that anybody can learn to use GABC (Gregorio) in five seconds to create Gregorian chant scores, I created this training video while holding a 6-month-old baby.

As easy as (G)ABC

Including newly typeset Gregorian chant in your booklets has never been easier.

15th Sunday in Ordinary Time (Year C)

This coming Sunday—13 July 2025—is the 15th Sunday in Ordinary Time (Year C). All the chants have been conveniently assembled and posted at the feasts website. The OFFERTORY, Ad Te Levávi, is particularly beautiful.

Music Director Job • $80,000 per year

Our readers will be interested in this job offering for Music Director at Saint Adalbert’s Basilica, located 40 minutes from where I live. My pastor was recently elevated to this basilica. He is offering $80,000 per year, plus benefits. I’m told Saint Adalbert’s Basilica is utterly gorgeous and contains one of America’s most magnificent pipe organs. It would be fantastic to have a colleague nearby!

Simplest “Agnus Dei” Ever Published

Our choir is on break during the month of July. I needed a relatively simple “Agnus Dei,” so I composed this setting for organ & voice in honor of Saint René Goupil. It has been called the simplest setting ever composed. I love CARMEN GREGORIANUM (“Gregorian Chant”), especially the ALLELUIAS, INTROITS, and COMMUNION ANTIPHONS. That being said, some have pointed out that certain sections of the Kyriale aren’t as strong as the Graduale or Vesperale. There’s a reason for this—but it would be too complicated to explain at this moment.

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).
