The Definition of Rock Music
Rock music is a broad genre of popular music that originated as “rock and roll” in the United States in the early 1950s, and developed into a range of different styles in the 1960s and later, particularly in the United Kingdom and in the United States. It has its roots in 1940s and 1950s rock and roll, a style which drew heavily on the African American genres of blues and rhythm and blues, and from country music. Rock music also drew strongly on a number of other genres such as electric blues and folk, and incorporated influences from jazz, classical and other musical styles. Musically, rock has centered on the electric guitar, usually as part of a rock group with electric bass, drums, and one or more singers. Typically, rock is song based music usually with a 4/4 time signature using a verse chorus form, but the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political.
