Paul Westermeyer is a teacher who has committed his life to the study of the music of the church in its two fundamental forms -- what the congregation sings and what the choir sings. The former is composed mostly of people who are not musicians, who sing around Word, font, and table without practice. The latter is composed of professional and amateur musicians who practice to help the congregation sing and to sing what it cannot.

Westermeyer's research suggests that the church sings in spite of all the attempts -- conscious and unconscious, internal and external -- to silence it and the study of its music. Though faced with many obstacles, the church through its musicians has created a remarkable musical repertoire and has continued to sing in season and out of season. The church's music provides a compelling testimony to the sustaining power of the Holy Spirit.
