The shag is a form of swing ancing that evolved from the jitterbug and jump blues of the big band jazz era and originated along the strands between Myrtle Beach, South Carolina, and Wilmington, North Carolina, during the 1940s. It is most often associated with beach music, a genre of rhythm and blues-based songs that lend themselves to this dance form. According to Bo Bryan, a noted shag historian and resident of Beaufort County, the term was coined at Carolina Beach, North Carolina. Today, the shag is a recognized dance in national and international dance competitions held across the United States.
