Catholic Liturgical Ensemble Formation

CLEF is an all-volunteer organization led by a board of ensemble directors, instrumentalists, singers, and liturgists who believe in the importance of ensemble music in liturgy. 

Our founding board members have extensive experience in music and liturgy, and they have been involved in a wide range of ensembles. We understand the unique challenges and opportunities for ensemble musicians and seek to provide education, skill building, and inspiration for ensemble musicians across the United States.
