Bach's Changing World is a study of popular culture in the community in which Bach spent the last, the longest, and the most productive part of his life: the Leipzig middle-class. The Leipzig middle-class evolved with the cooperation and gratitude of an extravagant, greedy, and disinterested absolutist ruler. Bach's Changing World documents how this community and other German communities responded toa variety of religious, social, and political demands that emerged during the years of the composer's lifetime. An accepted, admired, and trusted member of this community, as evidenced by the commissions he received for secular celebrations from royalty and members of the middle-class alike -- in addition to functioning as church composer -- Bach shared its values.

John Van Cleve analyzes the influence of the merchant class on what Leo Balet termed the Verburgerlichung (the 'becoming middle-class') of German literature during the eighteenth century. He describes the origins and development of the class and examines its successive images in works by Haller, Schnabel, Borkenstein, Luise Gottsched, J. E. Schlegel, Gellert, and Lessing. Between the years 1729 and 1750, merchants were better able to lend financial support to the literary world than were civil servants and professionals. Although merchants were central in the cultural life of the German states, they were usually less educated than other members of their social stratum and therefore less disposed to literature. Tradition has cast the merchant class in a highly unflattering light as ethically indefensible. Van Cleve's in-depth analysis traces the evolution of attitudes toward merchants from negative, underdeveloped images to positive, heroic portrayals.
