Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

“The Use of Plainsong in Heretical Worship” • (Letter by Dom Gregory Murray)

KIND READER brought to our attention an interesting letter written by Dom Andrew Gregory Murray, OSB (1905-1992). In my view, Dom Gregory was an excellent composer. Many of his organ interludes are masterpieces! (His famous People’s Mass is an aberration; it is uninspired, technically flawed, and insipid.) He served as organist and choirmaster at Downside from 1929 to 1940. Tension was caused amongst the other monks owing to the BBC constantly dragging their recording equipment to Downside to record Dom Gregory’s organ playing. In 1940, he left the Abbey to serve as a parish priest: at Ealing from 1940 to 1946; Saint Benedict’s Hindley (near Wigan) from 1948 to 1952, and Saint Benedict’s (Stratton-on-the-Fosse) from 1952 to 1987.

An excerpt from his letter:

Pope Pius X described plainsong as “the chant proper to the Roman Church, the only chant which she has inherited from the ancient fathers, which she has jealously guarded for centuries in her liturgical codices, which she directly proposes to the faithful as her own.” Plainsong, then, is the exclusive property of the Catholic Church, whose official liturgical music it is. The question of its interpretation, therefore, is not, and cannot be, for me a merely musical matter, for it is not merely music but the Church’s liturgical music. Moreover, if non-Catholics wish to discuss how it should be sung, it seems to me that they do so with the primary object of receiving assistance in the singing of plainsong in their own services. I am still further persuaded of this when I find the name of an “Anglican Benedictine” printed side by side with my own name on a leaflet advertising the discussion. I am not prepared to assist non-Catholics in the musical conduct of their services, nor will I take part in a discussion which is calculated to promote the use of the official liturgical music of the Church in heretical worship. I suggest, therefore, that unless Catholic musicians especially priests, are particularly careful in questions of this kind, they may easily encourage non-Catholics in the belief that the differences between Catholics and non-Catholics are of minor importance.

    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.

Quick Thoughts

    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.

When a friend speaks of his accomplishments and triumphs, he stands at a distance from our heart. When he shares his weaknesses and failings, he’s very near.
