Through sung prayer, members enjoy praising God, growing musically and spiritually, and enjoying each other’s friendship. The Choir helps the members of Saint Pius X (the gathered Assembly) to rightfully claim their role as full, conscious, and active participants in the liturgy through their gift of singing. The Choir enriches the congregation singing by adding harmonies and descants (Sing to the Lord, 29).

At times, the choir performs its ministry by singing alone. The choir may draw on the treasury of sacred music, singing compositions by composers of various periods and various music styles, as well as music that expresses the faith of the various cultures that enrich the Church (Sing to the Lord, 30).

The Saint Pius X Choirs are comprised of people from the community who possess the musical skills to sing in a choir by adding musical elements beyond the capabilities of the congregation alone (Sing to the Lord, 28). Choir members, like all liturgical ministers, should exercise their ministry with evident faith and should participate in the entire liturgical celebration, recognizing that they are the servants of the Liturgy and members of the gathered Assembly (Sing to the Lord, 32).
