Southern rock is a subgenre of rock music and a genre of Americana. It developed in the Southern United States from rock and roll, country music, and blues and is focused generally on electric guitars and vocals. Author Scott B. Bomar speculates the term "Southern rock" may have been coined in 1972 by Mo Slotin, writing for Atlanta's underground paper, The Great Speckled Bird, in a review of an Allman Brothers Band concert.

Rock is a broad genre of popular music that originated as "rock and roll" in the United States in the late 1940s and early 1950s, developing into a range of different styles from the mid-1960s, particularly in the United States and the United Kingdom. It has its roots in 1940s and 1950s rock and roll, a style that drew directly from the blues and rhythm and blues genres of African-American music and from country music. Rock also drew strongly from genres such as electric blues and folk, and incorporated influences from jazz and other musical styles. For instrumentation, rock has centered on the electric guitar, usually as part of a rock group with electric bass guitar, drums, and one or more singers. Usually, rock is song-based music with a 44 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. Rock was the most popular genre of music in the U.S. and much of the Western world from the 1950s to the 2010s.
