Empowering and connecting ensemble musicians

Online resources for ensemble musicians

We believe that ensemble music can open the hearts of the faithful so God can better reach and shape them. Our organization seeks to open the hearts of those who open the hearts of others.

Our CLEF Life online resources include both educational and inspirational content in the areas of music, liturgy, scripture, ministry, and spirituality.

About our organization

Catholic Liturgical Ensemble Formation (CLEF) is an all-volunteer organization that provides training, education, and an active support network to empower ensemble musicians to facilitate full, conscious, and active participation in the liturgy.

CLEF wouldn’t be possible without the generous support of our donors, volunteers, and online community. We invite you to join us in helping open the hearts of the faithful by supporting ensemble music in liturgy.
