West Coast Swing is a slow, improvised swing variation. Smooth, earthy, grounded, it is danced with spins, syncopations and musical breaks. The dance is said to have evolved from Lindy Hop and Swing when Hollywood started putting the dances on the screen. The width of the screen demanded the dance take on a lateral element in conjunction with the turns. West Coast Swing is most frequently danced to Blues and Jazz music, and more recently to Country and Western, and Disco.
