“I am a 25-year-old organist and cantor from the mountains of Northern Colorado. I wanted to take this opportunity to thank you and your friends for working hard to bring excellent content to your website and my inbox. I have found many, many awesome resources to help me stay faithful to the Church’s stance and traditions on good, beautiful sacred music at the local parishes for which I play the organ and cantor. Truly refreshing to see all the good content. Mere words fail me. I wish you could know how helpful you’ve been. I can sense your passion for this, and it’s contagious. We were able to start to implement the chanted antiphons in English, and I am more comfortable singing the traditional Latin propers at Holy Communion or Offertory. I have a tremendous appreciation for the beauty handed down by our forefathers, especially with the Extraordinary Form Mass… I wish we could have them more often, but good things are starting to happen to sacred music. Other church musicians I know and used to work with are grateful for your resources and hard work. You influence more people than you know!”

Music List • (2nd Sunday of Lent)

Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Which Mass?

In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

Extreme Unction

Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

PDF Chart • “Plainsong Rhythm”

I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

PDF • “O Come All Ye Faithful” (Simplified)

I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

“Our Christian people regard with great joy everything that contributes to the splendor of the ceremonies. Jesus—who was poor in His private life—received ointment on His feet. See Thomas Aquinas (Prima Secundae, q. 102, art. 5, ad 10) and the holy Curé of Ars. The Church has always loved beautiful churches, and so forth. We must preserve our sacred patrimony and make sure sacred objects do not become secular possessions.”
