While elements of rock and roll can be heard in blues records from the 1920's and in country records of the 1930's,the genre did not acquire its name until the 1950's.
Country music is a genre of United States popular music that originated in the Southern United States in the 1920's. It takes its roots from the southeastern genre of United States, such as folk music (especially Appalachian folk music), and blues music. Blues modes have been used extensively throughout its recorded history. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjos, electric and acoustic guitars, dobros and fiddles as well as harmonicas.
