‘Chant GPT’: How Catholics are responding to AI-generated Gregorian chant #Catholic In the early morning and late at night, monks still rise to sing the divine office, their voices low and hoarse from sleep. With every breath they are keeping alive a centuries-old tradition in monasteries around the world.But in a small corner of the internet, and on music providers like Spotify, another form of chant has taken hold. The text is often a hodgepodge of Latin-sounding words; a mechanical simulation not sung by human voices but generated by artificial intelligence (AI).How should Catholics navigate the new phenomenon of AI-generated chant, or, in the term hymnist Alan Hommerding coined, “Chant GPT”?What is Gregorian chant?Chant isn’t something that is consumed, like social media or food. Instead, it is a way to worship and pray, according to Catholic theologians and musicians.“Chant is not meant to be performed for artistic consumption but meant to attune our hearts to the Lord over the course of time,” Father Phillip Alcon Ganir, a Jesuit priest who teaches sacred music classes at Boston College, told EWTN News.

Composer and liturgist Father Ricky Manalo, a Paulist priest, agreed, adding: “Gregorian chant is not merely an aesthetic; it is part of the Church’s living tradition of sung prayer, as much as Gospel music is a living tradition for many African American Catholics, or pentatonic melodies are a living tradition for many East Asian Catholics.”“Its beauty is tied not only to its sound but to its liturgical, scriptural, and cultural roots,” he said.Named for St. Gregory the Great, Gregorian chant is a “musical synthesis” of Roman and Gallican chant, according to Father Basil Nixen, a monk of the Abbey of San Benedetto in Monte, Norcia, Italy, where the monks chant daily together. These chanted psalms continue to be prayed as part of the Divine Office, or Liturgy of the Hours — a daily practice for Catholic priests, religious, and laypeople.

“Many might assume that Gregorian chant is really a product of the medieval or dark ages from Western Christianity,” noted Giorgio Navarini, founder and director of the Catholic chant group Floriani Sacred Music. “However, Gregorian chant derives its existence from the Hebrew Temple. Sung psalmody, lamentations, and hymns were a significant part of the Hebraic liturgical life in both the synagogue and Temple.”In the Middle Ages came the “unprecedented notation” of the chant, which helped Gregorian chant spread, Nixen explained.“The sacred melodies of the chant were written by men and women inspired by the Holy Spirit, and every time we sing them, we allow the Holy Spirit to possess our hearts too so as to enter more fully into communion with God in prayer,” Nixen said.“Through the Divine Office the voice of Christ praying to his Father mingles with our own, allowing us to unite our voice with his and to participate in his priestly intercession for the salvation of the world,” Nixen said.How do we pray through Gregorian chant?Because Gregorian chant is more than just an aesthetic, questions about Gregorian chant are, at their root, questions about the connection between prayer and song.“Christian worship involves the whole human being — body and soul,” Nixen said. “Chanting is fundamental for Christian worship precisely for this purpose, because it allows us to pray not only with our minds but also with our bodies, our heart, our sentiments.”“Worship is the natural expression of the highest love, the love which most engages and engrosses us, which is why we owe it to God alone, whom we must love with all our hearts, all our minds, and all our strength — i.e., with body, heart, mind, and soul,” Nixen said. “And we do this most perfectly when we sing.”

Music, Navarini said, is “an art form that directly reflects the inner workings of the soul, unlike other art forms, which gives it a unique power of being united to prayer.”“Chant has the power to raise the soul to the divine,” Navarini said. “It is unlike any music in this world and truly provides a doorway and glimpse into the life to come.”Can machines pray?Human chant is meant to be just that — human, in every imperfection, hoarse voice, or flat note.“Even with AI aside, one of the dangers of chant recordings is that singers often aim to present pristine, errorless, and sublime sounds — which are good and holy in and of themselves,” Ganir said. “But such perfection is not often reflective of a life that worships regularly with chant.”The monks who chant daily in monasteries often sing with “tired” voices, Ganir observed.

“Sung prayer early in the morning or in the evening is often a different, usually 'tired,’ sound than prayers chanted during the day,” Ganir said.This isn’t a bad thing; in fact, it’s part of the deeper meaning behind chant.“Prayer is meant to span and intersect through all of life,” Ganir continued. “And music, especially our chant tradition, can be such a worthy and life-giving companion.”“AI-generated sacred-sounding music may have a place as a tool for study, preparation, or even private reflection, but it should not replace the living voice of the Church, the trained pastoral musician, the human composer, or the sung participation of the assembly,” Manalo said.

“AI can generate chant-like sounds or contemporary songs, but it cannot replace the faith, breath, body, and communal participation during a liturgy,” Manalo continued.“Sacred music requires theological depth, pastoral sensitivity, scriptural grounding, ritual awareness, and a sense of the actual community that will sing or hear it,” Manalo said.“Every true prayer is an authentic and personal encounter of trust between a creature with its Creator, a recognition of our dependence on the one who is infinitely good,” Father Ezra Sullivan, a Dominican priest and director of the Spirituality Institute at the Angelicum, told EWTN News.“There is an old saying: ‘You cannot give what you do not have,’” Sullivan continued. “Because an algorithm does not have a knowledge and love of God, no person to have a relationship with him, it cannot make prayers or music that authentically express the raising up of the soul to the hands of our loving Father — even if it makes imitations that are somewhat pleasing, the soul would be missing.”“One of the reasons why we like to know the biography of composers or authors is because when we read their works or listen to their music, we can commune with them across the ages and join our souls with theirs in coming closer to God,” Sullivan continued. “Artificial intelligence might be able to fool us into thinking that it facilitates these horizontal and vertical relationships, and thatʼs precisely how it can be dangerous in the spiritual realm.”

In Pope Leoʼs recent encyclical letter, Magnifica Humanitas, the Holy Father wrote: “No computational system, however sophisticated, can create a heart that gives itself, or a conscience that discerns good from evil.”“Gregorian chant is what the soul sings to God; it is what a bride sings to her Divine Bridegroom,” Nixen said. “If an AI-generated thing can love and get married, then it can sing chant. If it can get baptized, then it can sing chant. But if it cannot love, get married, get baptized, or be united to God, then it cannot chant.”

As AI encroaches on sacred music, Catholics still hold true to Gregorian chant, a historical form of sacred music that is still alive today.
