​The Church of the Good Shepherd is committed to fostering excellence in congregational song and prayer. The Fathers of the Second Vatican Council hailed the Church's rich tradition of Sacred Music as "a treasure of inestimable value, greater even than that of any other art." As such, the Church states that music is not merely an ornament or nicety, but "a necessary or integral part of the solemn liturgy." Because Holy Sacrifice of the Mass is intended to be a foretaste of the Heavenly Banquet, it is essential that the quality of our sacred music reflect the beauty of the Eternal.

Adult Choir Sing in the adult choir during weekend Masses and Holy Days of Obligation. This requires attending weekly rehearsals during the choir season, arriving 40 minutes ahead of Mass for warmups and practice, and singing during Mass. The adult choir generally sings at three 10:30am Masses per month from September through May. Additionally, the adult choir generally sings at the 7pm Mass on Holy Days of Obligation, on Holy Thursday, on Good Friday, at the Easter Vigil, at both Christmas Eve Masses, at both Christmas Day Masses, and during Solemn Vespers on Good Shepherd Sunday. The choir sings a diverse spectrum of choral music, including chant; Renaissance polyphony; cantata and oratorio repertoire by such composers as Bach, Vivaldi, Handel, and Mendelssohn; and good deal of varied styles such as the Italian, French, Russian, and German traditions, Latvian contemporary music, and English Cathedral repertoire. Those who wish to sing in the adult choir must display willingness to commit to scheduled rehearsals and Masses, ability to match pitch, and ability to carry a tune. An advanced knowledge of music is not required. This ministry is open to all parishioners from 9th grade and up.

Cantor Lead the congregation in song during weekend Masses. This requires arriving 30 minutes ahead of Mass to practice with the Organist & Choirmaster, introducing the Mass of the day, leading congregational singing, and leading the responsorial psalm. Frequency of service is dependent upon the total number of volunteers. Service as a cantor is dependent upon a satisfactory audition with the Organist & Choirmaster. This ministry is open to all parishioners from 5th grade and up.

Youth Choir Sing in the youth choir during weekend Masses. This requires attending weekly rehearsals during the school year, arriving 40 minutes ahead of Mass for warmups and practice, and singing during Mass. The youth choir generally sings at one 10:30am Mass per month from October through May. Those who participate in the youth choir learn the musical tradition of the universal Church, and they are enthusiastic about it! By singing in a choir, young people can develop a sense of professionalism and pride in what they do. This will have a positive impact on their religious education and understanding of the liturgy. This ministry is open to all parishioners in 4th through 8th grade.
