American Smooth loosely corresponds to the Standard category of International Style Ballroom Dance, just like Rhythm loosely corresponds to Latin. However, Smooth differs from Standard in its inclusion of open and separated figures, whereas Standard makes exclusive use of closed positions.
The Smooth dances themselves are significantly different than the Standard dances as a result of influence by dancers like Fred Astaire and Arthur Murray in the years following World War II. While elegance and flow remain the goal, as in International Standard, dancers do not remain in closed position exclusively, instead breaking away from each other periodically and experimenting with open footwork.
American Smooth, just like American Rhythm, is mostly danced in the United States and Canada, while International Style Latin and International Style Standard are danced internationally, all around the world.Standard dances are normally danced to Western music (often from the mid-twentieth century), and couples dance counter-clockwise around a rectangular floor following the line of dance.
Dancers wear costumes not greatly dissimilar to those worn by their counterparts in Standard. Standard dresses often have prominent floats embellishing the arms and fuller skirts which are typically absent in Smooth, due to the open movement and changing arm positions that require less restriction on the body.
