Rock is a form of popular music that emerged in the 1950s and that by the end of the 20th century was the world’s dominant form of popular music. It originated in the United States and spread to other English-speaking countries and across Europe in the 1960s.
Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. The three major classes of rock are igneous, sedimentary, and metamorphic rock.
Rock history can thus be organized around both the sound of cities (Philadelphia and Detroit, New York City and San Francisco, Liverpool and Manchester) and the spread of youth cults (rock and roll, heavy metal, punk, and grunge).
Though rock has used a wide variety of instruments, its basic elements are one or several vocalists, heavily amplified electric guitars (including bass, rhythm, and lead), and drums.
