Ann Arbor, Michigan, Aug 17, 2025 / 06:00 am (CNA).

The setting: a suburban Michigan parish.

The agenda: a crash course in Gregorian chant as well as posture, breathing, and other elements of sacred choral music.

The attendees: youth ages 8 to 18.

Canticle Chant Camp was held at St. Thomas the Apostle Parish in Ann Arbor, Michigan, from July 28 to Aug. 1 and was attended by more than 40 children and teens. The camp ended with a sung Mass.

The instructor was veteran choral director and educator Mary Ann Wilson. 

Wilson, who holds degrees in music, was trained in opera and Gregorian chant in Europe and has taught for nearly 30 years. She told CNA that she enjoys sharing “the glories of Gregorian chant, which uniquely fosters a sense of peace and joy that connects the whole person to God.” 

Referring to sacred music, she added: “It’s important to pass down this tradition. Beautiful sculpture, paintings, architecture, and stained-glass windows can last hundreds of years: All of them help us to pray. But music, once it is performed, is gone. It’s an offering to the Lord in real time. And if we don’t hand it down with every generation, we lose it.”

Wilson is president of the nonprofit apostolate Canticle.org, founded “to draw souls to Jesus Christ through the beauty of sacred music.” She has served as a parish music director and has led choirs singing Gregorian chant and renaissance polyphony. Since 2010, she has led the “Chant Camp” program at dozens of parishes and schools. She also trains teachers, choir directors, and cantors to lead camps themselves and foster sacred music.

In addition, Wilson is a consultant to the Benedict XVI Institute, which seeks to instill a sense of the sacred in the arts and worship throughout the country. She said she has received encouragement from Archbishop Salvatore Cordileone of San Francisco, a board member of the institute, in her quest to promote traditional liturgical music.

During the camp, Wilson did a deep dive into the prayers and structure of the sung Mass. Her directive: “Everybody can sing something, and nobody sings everything.”

Students learn the “Kyrie” and “Sanctus,” for example, while the more experienced get practice in more difficult chants. “What they learn is to sing together as their offering during the Mass.”

Practice in traditional hymns such as “All Glory, Laud, and Honor” and Gregorian chant adapted to English were also on the bill.

Wilson said she feels blessed to share her expertise with youth. 

She recalled that while studying musical performance and pedagogy at San Diego State University, she gained an appreciation for the beauty of the Church’s tradition of polyphonic singing. “I found myself singing polyphonic Masses at a secular university,” she observed, adding: “This music is for everybody.” 

Jeanne Marie Gerig, organist and music director at St. Thomas, told CNA that the canticle camp is just the beginning of an expanding parochial music program, especially for children. Gerig, a convert who was inspired to enter the Church because of its sacred music, said that while the parochial school has its own music program, home-schoolers and parents from other parishes are also seeking enrichment for their children.

“They will learn different settings of the Mass because every season should sound different. Easter should sound different, Christmas should sound different, and not just look different,” she said. “They will learn to read music, sing it, and sing in Mass.”

“Parents welcome the opportunity for kids to become more knowledgeable about singing music that is part of our heritage and used for liturgy,” Gerig said.

Gerig is an active member of the Catholic Music Association of America and continues to consult at parishes around the country, supported by offering online courses in Gregorian chant offered by the Catholic Institute of Sacred Music of California. She told CNA that she is especially pleased to offer such instruction to young people.

“By learning music, they can serve God and their community and contribute to the liturgy in a meaningful way, and help others to pray and worship,” she explained, adding that the goal is to offer the chant camp every summer. She hopes that the canticle camp will spark interest in the parish’s Laudate Youth Choir and the Pueri Cordis Jesu schola.

The parish’s choir directors also support these chant-based initiatives.

Hannah Bingham, a trained music educator and recent convert, told CNA that she will be directing three singing ensemble options for the Laudate Youth Choir, grouped according to age from 8 to adulthood.

“It’s open to any youth in the area who want to use their voice to glorify God,” she said, referring to nearby parishes where youth choirs haven’t been established. “We want to expose them to Masses at different parishes. We hope for a unifying and uplifting experience, not only spiritually but also building friendships and community.”

University of Michigan music major Lucia Skrobola will lead Puer Cordis Jesu, a schola choir for ages 8 to 18 focusing on Gregorian chant and Latin polyphonic hymns for the Mass in the extraordinary form at the parish. She said participants will sing at Mass monthly and at festivals.

“Gregorian chant is the prayer of the Mass. I’ve come to realize how beautiful it is and that it brings out the reverence of the liturgy in a way other music does not,” she said.
