Beach music, also known as Carolina beach music, and to a lesser extent, Beach pop, is a regional genre of music in the United States which developed from rock/R&B and pop music of the 1950s and 1960s. Beach music is most closely associated with the style of dance known as the shag, or the Carolina shag, which is also the official state dance of both North Carolina and South Carolina. Recordings with a 4/4 "blues shuffle" rhythmic structure and moderate-to-fast tempo are the most popular music for the shag, and the vast majority of the music in this genre fits that description. Though primarily confined to a small regional fan base, specifically to "Grand Strand" communities such as Myrtle Beach, Carolina Beach, and the Golden Isles of Georgia, in its early days what is now known as Carolina beach music was instrumental in bringing about wider acceptance of R&B music among the white population nationwide. Thus it was a contributory factor in both the birth of rock and roll and the later development of soul music as a subgenre of R&B. While the older styles of R&B have faded from popularity nationally, the Carolina shag has gained wide popularity in dance circles around the US. This has not generally led to increased appreciation for the music of the beach bands, however. Many of these new shag dance aficionados prefer the "R&B oldies" and/or shagging to currently popular tunes that happen to have the required beat. As more networking is being done on the Internet among shag deejays and beach music fans nationwide, however, there is a growing acceptance of the regional bands by the "new shaggers". History Origins: 1950s Historical accounts of beach music as it relates to the development of this dance are often conflicting, but most agree that the Ocean Drive section of North Myrtle Beach, South Carolina is where the beach/shag phenomenon had its greatest impact among vacationing teenagers and college students. The early development started around 1950. In the period from roughly the end of World War II through the mid-1950s, many white youth in the still-segregated South could not always hear the compelling music of primarily black popular recording artists in their home towns. At the time, much of these recordings were characterized as "race music", a term later replaced by "R&B." In some communities, this remained in effect even after racial desegregation was implemented
