This dissertation investigates how German-language critics articulated and publicly negotiated ideas about music and expressionism in the first five years after World War I. A close reading of largely unexplored primary sources reveals that "musical expressionism" was originally conceived as an intrinsically musical matter rather than as a stylistic analog to expressionism in other art forms, and thus as especially relevant to purely instrumental rather than vocal and stage genres. By focusing on critical reception of an unlikely group of instrumental chamber works, I elucidate how the acts of performing, listening to, and evaluating "expressionist" music were enmeshed in the complexities of a politicized public concert life in the immediate postwar period. The opening chapters establish broad music-aesthetic and sociopolitical contexts for critics' postwar discussions of "musical expressionism." After the first, introductory chapter, Chapter 2 traces how art and literary critics came to position music as the most expressionist of the arts based on nineteenth-century ideas about the apparently unique ontology of music. Chapter 3 considers how this conception of expressionism led progressive-minded music critics to interpret expressionist music as the next step in the historical development of absolute music. These critics strategically—and controversially—portrayed Schoenberg's "atonal" polyphony as a legitimate …

This dissertation contextualizes Brahms's vocal quartets within a largely forgotten discourse about Hausmusik that flourished in German-speaking lands in the second half of the nineteenth century. In numerous texts about Hausmusik from ca. 1848-1900, authors conceived the genre as an aesthetically and politically conservative expression of German identity and connected its accessible style to an ideal of social cohesion in the pre-industrial age. Similar issues of national identity and musical style arise in the reception of Brahms's quartets, which, I contend, was informed by the works' generic status as Hausmusik. Critics either praised Brahms's works for their simple, folk-like style or disparaged their complexity, artifice, and foreignness. Ultimately, I argue, Brahms sought to elevate the genre of Hausmusik in his vocal quartets by integrating aesthetic and cultural values associated with this genre with a more sophisticated musical style. The works' stylistic and generic ambiguity and the disparity in critics' responses reveal competing aesthetic, political, and cultural world views immediately before and after German unification. Chapter 2 shows how discourse about Hausmusik constructed German identity in the private sphere by promoting a folk-like aesthetic and accessible musical style over the perceived cosmopolitanism and commercialism of Salonmusik and other repertoires.
