Choir
A body of singers who provide musical leadership for congregational singing in the worship of the church. Choirs may also sing anthems or make other special musical offerings to beautify and enhance the experience of worship. The primary role of the choir is to lead and support the congregation's worship through singing, not to provide a musical performance. Choir members may wear a cassock and surplice, or an alb. Some choirs do not wear vestments. The choir may be placed in a section of the chancel (also known as the “choir” or “quire”), or the choir may sit together in a designated part of the nave.
