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.

Ken Gilman, PhD

Ken served for 17 years as music director at St. Michael & All Angels in Albuquerque. He continues to play in his preferred spot on the back row at St. Michael and at St. Charles Borromeo, usually as an obbligato person on mandolin, octave viola, tenor, or bass mandolin. Irish banjo may even have snuck in a time or two. In Albuquerque the past 20 years, he previously worked and played in Celtic bands in both New England (Maine) and Europe (Belgium).

His special passion is creating balance in the ensemble for instruments and voices. In music selection and arrangement, he loves to explore, in addition to lyric content, how the timbre, rhythmic, and melodic characteristics of the music support the flow of the liturgy. Another area of interest for Ken is how we inhabit the continuum of the political to the pastoral, and how the interplay of beliefs and personality combine with the practice of authority and leadership to affect ensemble formation at all levels of the community, from staff to choir/ensemble to assembly. As a semi-retired psychologist and mediator, he does supervision and training work primarily with first responders around teamwork, communication, burnout, and self-care.

Peter Maher

Peter Maher earned a bachelor’s degree from the Catholic University of America in 1978. He is currently enjoying retirement after a varied career, including stints as an executive chef, owner-operator of a highly successful computer operations company, and 16 years with the National Association of Pastoral Musicians. Peter began his career as an ensemble musician in 1969 when Sister Maureen, who knew he played guitar, asked him to help form the first folk group in the parish. Aside from a few breaks for life and jobs along the way, he has been an ensemble musician since that time.

Steve Petrunak

Steve Petrunak is the director of music at St. Blase Parish in Sterling Heights, Michigan, where he has served in music ministry for more than 43 years.
