German musicology has customarily situated a paradigm shift in musical aesthetics some time during the first half of the sixteenth century. This dissertation examines the suggestion that German Reformation theology inspired a modern musical aesthetic. In Part One, the existing narrative of relationship between theological and musical thought is tested and rejected. Chapter 1 analyses twentieth-century music historians' positive expectation of commensurability between Luther's theological ideas and the sixteenth-century concepts of the musical work and musical rhetoric, concluding that their positive expectation was dependent on a Germanocentric modernity narrative. Chapter 2 assesses Listenius' Musica (1537), the textbook in which the concepts of the musical work and musica poetica were expounded for the first time. I argue that, since Listenius' textbook was intended as a pedagogical tool, it is inappropriate to read his exposition of musica poetica and opus as if logical sentences on musical aesthetics. Part Two investigates the treatment of musica in the theology of early German Reformation disputants. Chapter 3 finds that Luther's early musical thought was borrowed from the late mediæval mystics, and resisted the influence of the Renaissance Platonists. Chapter 4 shows that, far from embracing humanist ideas of musical rhetoric, Luther's Reformed musical aesthetic became increasingly anti-rational and sceptical of music's relation to verbal meaning. Chapter 5 examines the discussions of music by the German Romanist polemicists. It finds that their music-aesthetic assertions were opportunistic attempts to situate the Lutherans outside the bounds of orthodoxy. The dissertation concludes that the discussions of music in early German Reformation texts ran counter to the general sixteenth-century trajectory towards a humanistic or modern aesthetic of music. It further argues that the aesthetic proposals of sixteenth-century German theologians should be taken seriously in the formation of our present-day picture of sixteenth-century musical thought.

Les auteurs des Flugschriften mènent un combat pour la paix, chacun à sa manière. Luther veut sauvegarder la paix ; l’assemblée commune des autorités et des sujets de l’Ortenau veut rétablir la paix ; Melanchthon veut consolider la paix. De quelle paix s’agit-il ? Tout d’abord, le renoncement à la violence. Il s’agit essentiellement de sauvegarder la paix civile. Les Réformateurs, surtout Melanchthon, associent volontiers cette paix toute « extérieure » à la paix « intérieure que procure Dieu dans le cœur de celui qui place sa confiance en Lui. ». La paix ne peut pas être fondée sur un usage abusif de l’Ecriture. Luther dénonce le Droit divin qui, à ses yeux, relève d’un mésusage de l’Ecriture, et prône le « droit chrétien » : souffrir, et invoquer Dieu. L’assemblée commune des autorités et des sujets à Renchen ignore totalement ce Droit divin. Melanchthon condamne le recours à ce Droit divin. Aux arguments bibliques avancés par les paysans pour justifier leurs griefs et leur programme, Melanchthon en oppose d’autres pour récuser les XII articles. Luther le rappelle aux princes et aux seigneurs : ils doivent s’attacher à la Parole de Dieu ; qu’ils tiennent compte des articles des paysans qui sont souvent « justes et équitables » ; qu’ils engagent des négociations en vue d’une conciliation. Aux princes et aux seigneurs Melanchthon adresse ses suppliques pour assurer la paix future. Luther demande aux paysans de renoncer au Droit divin ; qu’ils adoptent le droit chrétien et qu’ils se gardent des faux prophètes ! Melanchthon déclare : le maintien de la paix implique pour le chrétien quelques renoncements et obligations. L’Ecriture condamne le recours à la violence illégitime. / The authors of the Flugschriften lead a combat for peace, each one in his own way. Luther wants to preserve the peace; the common assembly of the authorities and the subjects of the Ortenau want to re-establish the peace; Melanchthon wants to consolidate the peace. But what peace is involved here? First of all, it is a combat against violence. This is essentially about preserving civil peace. The Reformers, especially Melanchthon, happily associate this “outer peace with the “inner” peace that God brings to the heart of the one who places his confidence in Him”. Peace cannot be founded on an abusive use of Scripture. Luther denounces Divine right that, in his eyes, is a misuse of Scripture, and rather extols “Christian law”: to suffer, and to invoke God. The common assembly of the authorities and subjects in Renchen totally ignores Divine right. Melanchthon condemns any recourse to this Divine right. To the biblical arguments advanced by the peasants for justifying their grievances and their programme, Melanchthon opposes other arguments to challenge the XII articles. Luther does not forget to remind the princes and lords that they must focus on the Word of God; that they should take into account the articles of the peasantry which are often “just and equitable”. They should engage negotiations with a view to conciliation. Luther asks the peasants to renounce Divine right, that they adopt Christian law and keep themselves from false prophets! To the princes and the lords Melanchthon addresses his petitions in order to assure future peace. Melanchthon declares: Keeping the peace for the Christian involves certain renouncement and obligations.
