Belly dance is a Western-coined name for a type of Middle Eastern dance. Originally a "solo, improvised dance involving torso articulation", belly dance takes many different forms depending on the country and region, both in costume and dance style, and new styles have evolved in the West as its popularity has spread globally.The term "belly dance" is a translation of the French term "danse du ventre", which was applied to the dance in the Victorian era, and probably originally referred to the Arabic tribe Ouled Nail dancers of Algeria, whose dance used more abdominal movements than the dances described today as "belly dance". It is something of a misnomer, as every part of the body is involved in the dance; the most featured body part is usually the hips. In Arabic, the dance is known as "Raqs Sharqi" ("Eastern Dance") or "Raqs Beledi" ("Country Dance" or "Folk Dance"). 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 relaxed, natural isolations of the torso muscles, rather than on movements of the limbs through space. Although some of these isolations appear superficially similar to the isolations used in jazz ballet, they are sometimes driven differently and have a different feeling or emphasis. In common with most folk dances, there is no universally codified naming scheme for belly dance movements. Some dancers and dance schools have developed their own naming schemes, but none of these are universally recognised. Movements found in belly dance Many of the movements characteristic of belly dance can be grouped into the following categories: Percussive movements - Staccato movements, most commonly of the hips, which can be used to punctuate the music or accent a beat. Typical movements in this group include hip drops, vertical hip rocks, outwards hip hits, hip lifts and hip twists. Percussive movements using other parts of the body can include lifts or drops of the ribcage and shoulder accents. Fluid movements - Flowing, sinuous movements in which the body is in continuous motion, which may be used to interpret melodic lines and lyrical sections in the music, or modulated to express complex instrumental improvisations, as well as being performed in a rhythmic manner. These movements require a great deal of abdominal muscle control. Typical movements include horizontal and vertical figures of 8 or infinity loops with the hips, horizontal or tilting hip circles, and undulations of the hips and abdomen. These basic shapes may be varied, combined and embellished to create an infinite variety of complex, textured movements. Shimmies, shivers and vibrations – Small, fast, continuous movements of the hips or ribcage, which create an impression of texture and depth of movement. Shimmies are commonly layered over other movements, and are often used to interpret rolls on the tablah or riq or fast strumming of the oud or qanun (instrument). There are many types of shimmy, varying in size and method of generation. Some common shimmies include relaxed, up and down hip shimmies, straight-legged knee-driven shimmies, fast, tiny hip vibrations, twisting hip shimmies, bouncing 'earthquake' shimmies, and relaxed shoulder or ribcage shimmies. In addition to these torso movements, 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. Other movements may be used as occasional accents, such as low kicks and arabesques, backbends, and head tosses.
