Music Ministers provide the vocal and instrumental support proper to the actions of a given liturgy.  Followed closely by Lectors and Children’s Liturgists, Music Ministers require the greatest amount of preparation prior to Mass, as music must be rehearsed and new music must be learned prior to use.  Vocalists may be organized into choirs, small cantor groups, or single cantors, depending on each person’s schedule.  Instrumentalists consist of Accompanists, one of whom normally coordinates a given group, and any additional instruments available for the liturgy.  While fluency in reading music is not an absolute requirement, it is highly encouraged due to the wide repertoire associated with changing liturgical seasons and events.
