Cantus Firmus and the Auditory Body: Reading Nicolai’s Chorale in BWV 140 as Traditionalization

In the Lutheran church music tradition, the placement of pre-existing chorale melodies as cantus firmus in new compositions constitutes a stable compositional practice extending from the sixteenth through the eighteenth century. Musicological literature has generally treated this practice as a formal technique or theological reference; however, neither its authoritative function nor its embedding within the auditory body of the congregation has been systematically examined within a theoretical framework. This study addresses this gap by taking Johann Sebastian Bach’s use of Philipp Nicolai’s 1599 chorale as cantus firmus in the opening chorale fantasia of Wachet auf, ruft uns die Stimme BWV 140, 1731 (Wake, Awake, for Night is Flying) as a two-layered analytical case. The study adopts Catherine Bell’s concept of ritualization as developed in Ritual Theory, Ritual Practice (1992) as its theoretical framework, operationalizing two specific analytical concepts from within this framework: traditionalization (the strategy of legitimizing the new by binding it to the authority of the old) and ritualized body (the embodied internalization of ritual practice). The first concept is employed to analyze the hierarchical contrast between the fixed cantus firmus position of Nicolai’s chorale and the mobility of the surrounding polyphony; the second is developed as an original analytical proposal examining how the chorale may function as a structural spine within the auditory body of the congregation. The article argues that Bach’s gesture of chorale placement can be understood not only as a musical technique or theological reminder, but as both a traditionalization act that strategically invokes inherited authority and a ritual structuring that may have been collectively experienced within the auditory body of the listening congregation. This reading proposes a new perspective on the cultural-strategic and embodied dimensions of compositional practices in Lutheran liturgical music research, and aims to contribute methodologically to the analytical study of Bach’s chorale cantatas at the intersection of ritual theory and musicology.
