‘Music and confession in Heidelberg, 1556–1618’ Matthew Laube, Royal Holloway, University of London matthew.laube.2009@live.rhul.ac.uk This thesis examines the close relationship of music and religion in the city of Heidelberg in the turbulent period between its first fervent Lutheran reforms (1556) and the start of the Thirty Years’ War (1618). Examining the theory of confessionalisation in relation to music, my PhD challenges the theory’s central premiss that, in the process of building unified states and using social discipline to enhance secular power, ‘the three great confessions – Catholicism, Lutheranism and Calvinism – developed into internally coherent and externally exclusive communities distinct in institutions, membership and belief’.i By Electoral decree, Heidelberg’s parish churches, university, schools and Electoral court violently oscillated four times between Lutheran and Reformed (Calvinist) confessions between 1556 and 1618. Although each change caused confessional tension throughout the city, Heidelberg’s musical spheres showed continuities as much as discontinuities both within learned circles and on the popular level. Music offers a useful scholarly lens on confessionalisation, not only because it was performed in sacred and secular contexts, but also because music’s aural and textual qualities enabled a greater permeation of society than other communicatory or devotional media such as Bibles, catechisms and visual art. My thesis consists of an introduction and four chapters: ‘Hymns and hymnbooks’, examining the printing, circulation and uses of hymns and hymnbooks as tools of confessionalisation. The analysis of official printed hymnbooks alongside manuscript hymns and hymnbooks reveals that Lutheran and Calvinist hymn cultures were never fully distinct, but drew on common origins and complementary aims of vernacular singing. ‘Music and cultural exchange’, investigating how Heidelberg’s musical culture was influenced by the large number of foreign visitors to the city. Not only was Heidelberg’s print culture marketing foreign music, but the inflow of university students, refugees and court visitors created a more diverse musical culture than heretofore observed. ‘Music and education’, considering how strategies and goals of music education were shared by Lutherans and Calvinists. The career paths of two former Heidelberg university students who became professional musicians are traced as micro-historical case studies of how confessional lines were negotiated and transgressed. ‘Music and courtly festivities’, exploring how the desire for musical splendour commensurate to princely status was achieved in light of not only confessional tensions but also music’s ephemeral nature. Extant commemorative books reveal that strategies for musical splendour were regulated by imperial expectations and also local traditions. This thesis brings together hitherto unknown archival material and numerous printed sources with theories of cultural history, material culture and cultural exchange to challenge misunderstandings about Reformed musical culture, to show the extensive overlapping of Reformed and Lutheran musical cultures, and to explore the relationship of confessionalised music to pre-Reformation religious and political networks.
