Belly dance is an expressive dance which emphasizes complex movements of the torso. Originally a Middle Eastern folk dance, it has evolved to take many different forms depending on the country and region, both in costume and dance style. New styles have evolved in the West as its popularity has spread globally.
Belly dance is primarily a torso-driven dance, with an emphasis on articulations of the hips. Unlike many Western dance forms, the focus of the dance is on isolations of the torso muscles, rather than on movements of the limbs through space. Although some of these isolations appear similar to the isolations used in jazz ballet, they are sometimes driven differently and have a different feeling or emphasis.
Dancers in many styles will use level changes, travelling steps, turns and spins. The arms are used to frame and accentuate movements of the hips, for dramatic gestures, and to create beautiful lines and shapes with the body, particularly in the more balletic, Westernised styles.
