This chapter zooms out to examine the broader historical and stylistic context of rock. The roots of rock—especially in common-practice music, the blues, and Tin Pan Alley / jazz—have been widely discussed, but this chapter attempts to identify more systematically the features that rock shares with these previous styles, as well as its unique features. A historical survey of rock itself and its various subgenres finds that it underwent major changes in the early 1960s but remained rather stable over the next three decades, and in some respects rather homogenous. The chapter then considers some other genres with which rock has interacted and sometimes fused: folk, Latin pop, jazz, electronic dance music, rap, and country. Finally, it considers the development of rock since 2000, finding some changes in the style but also many continuities.
