Surf music is a genre of popular music associated with surf culture, particularly Orange County and other areas of Southern California. It has two basic sub genres: (1) Surf pop music, including both surf ballads and dance music that includes a vocal line. Sometimes called "beach music" as it was popular amongst non-surfers as well. (Surf pop should not be confused with the "shag tempo" beach music of the Carolinas, however.) And (2) Surf rock, generally instrumental in nature with an electric guitar or saxophone playing the main melody. Many notable surf bands have been equally noted for both surf instrumental and surf pop music, so surf music is generally considered as a single genre despite the variety of these styles. .
