This chapter looks at string quartet transcriptions and arrangements. These arrangements differ from their piano-oriented counterparts in significant ways, and they reflect the changing role of chamber music—and that of opera and folk song—in musical life over the course of the nineteenth century. In translating an opera or other work for string quartet, arrangers combined seemingly opposed genres and social settings, bringing the opera house into the parlor in some cases and the countryside into the city in others. The chapter then focuses on Berlin-based publisher Adolph Martin Schlesinger. His firm produced dozens of opera transcriptions, collections of folk songs, and arrangements of Classical works for amateur chamber musicians between 1800 and 1900.
