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.”

Blessed are the Peacemakers

Peace among men cannot come from hearts that are not at peace. Peace of soul is something only God can give us, and without it, we are lost.

The Spirit of Solesmes

The unification of our lives, the orientation to the ultimate goal that gives meaning to every proximate and particular goal we seek, is the work of the sacred liturgy.

What Vatican II Said (and Didn’t Say) about the Liturgy

Vatican II presents a mystical, contemplative, symbolic vision of liturgy, the celebration of which John Paul II said “must be characterized by a profound sense of the sacred.” Is it what you experience at your local parish?

Can We Ever “Understand” the Mass?

Those who take away the density of ritual and the solemn beauty of the ineffable will not gain more worshipers; they will merely give them more reasons to go away and find something more interesting to do.

Beethoven’s “Missa Solemnis”

Music history textbooks often speak of Beethoven’s Missa Solemnis as no more than a purely artistic statement, when in reality it is a testimony to his deep, if idiosyncratic, Catholic faith.

Discerning Changes in the Old Missal

Could there be room for legitimate changes to the Missal of 1962, the last typical edition of the traditional Roman Rite of Mass or the “extraordinary form”?

Dr. Peter Kwasniewski · May 16, 2013

The Distracting Prayer of the Faithful

Looking at the structure and flow of the liturgical action, the Prayer of the Faithful marks a most awkward caesura in the liturgical action. We would be better off without them.

On the Wonder and Strangeness of Sacred Music

The Church’s liturgy, since it is the Passover Feast, has to bring us out of the world, out of Egypt. So it ought to have a certain “strangeness” about it.

Dr. Peter Kwasniewski · May 2, 2013

Music of High Artistic Value

The papal teaching addresses precisely the question of criteria; it does not attempt to teach people how to listen to music or how to discriminate different qualities of music. If such discriminatory abilities are lacking, the papal teaching can have no meaning for us.

Dr. Peter Kwasniewski · April 25, 2013

Music as a Character-Forming Force

The spiritual maturity of the Christian is very much connected with habituation in the nobility of the fine arts.

Dr. Peter Kwasniewski · April 18, 2013

On Correcting Deviant Liturgical Customs

The longer the hermeneutic of rupture and its expressions are allowed to continue, the longer a “Great Schism” between the preconciliar and postconciliar periods will be perpetuated. There is a real, pressing, desperate need for healing, reconciliation, and reunification.

Dr. Peter Kwasniewski · April 11, 2013

Why Liturgical Bad Habits Must Be Broken

The Church is not built up and strengthened when her pastors ignore her conciliar teaching, repudiate her tradition, violate her rubrics and instructions, and merrily accept the status quo in all its mediocrity.

Dr. Peter Kwasniewski · April 4, 2013

Can Theology and Liturgy Be Divorced?

Truly it would not be presumptuous to say that, in a liturgy completely centered on God, we can see, in its rituals and chant, an image of eternity.

Dr. Peter Kwasniewski · March 28, 2013

Banish All Guitars and Pianos from the Church

The increasingly obvious failure of contemporary church music should occasion a more widespread rejection of piano and guitar as accompanying or interluding instruments.

Dr. Peter Kwasniewski · March 21, 2013

On Listening to Good Music

Some people say that today’s popular music is “more emotional” while traditional music is “less emotional.” In reality, emotions evoked in popular music are more crude and monotonous. Emotions elicited by the music of Palestrina, Bach, or Mozart, being more intellectual, are more profound and pure.

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.

We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe!

    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.”
    —Jeff Ostrowski
    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.
    —Jeff Ostrowski

Random Quote

On 26 July 1916—during the German occupation of Belgium—a student choir led by Van Nuffel performed his setting of the psalm “Super flumina Babylonis” in Saint Rumbold’s Cathedral. The text and the musical setting very aptly expressed the depressed and rebellious mood of the population. The acclaim was enormous, and it laid the foundation for Van Nuffel’s formation of the Saint Rumbold’s choir.
