Formed in late 2021, we are a 501(c)(3) nonprofit organization dedicated to supporting ensemble-led Catholic liturgy by offering training, education, and connection to community for ensemble musicians across the United States.

CLEF Life offers resources to help ensemble musicians grow and excel in their ministry and builds community among those who value ensemble music-making as a way to lead the people of God to experience better worship through full, conscious, and active participation.

CLEF Summer Program

The CLEF Summer Program is an in-person event held each summer at the Jesuit Spiritual Center in Milford, Ohio. Ensemble musicians from across the country gather for a week of prayer, education, skill-building, and community.
