Dance is a performing art form consisting of purposefully selected sequences of human movement. This movement has aesthetic and symbolic value, and is acknowledged as dance by performers and observers within a particular culture. Dance can be categorized and described by its choreography, by its repertoire of movements, or by its historical period or place of origin.
Participatory dance, on the other hand, whether it be a folk dance, a social dance, a group dance such as a line, circle, chain or square dance, or a partner dance such as is common in western Western ballroom dancing, is undertaken primarily for a common purpose, such as social interaction or exercise, of participants rather than onlookers. Such dance seldom has any narrative. A group dance and a corps de ballet, a social partner dance and a pas de deux, differ profoundly. Even a solo dance may be undertaken solely for the satisfaction of the dancer. Participatory dancers often all employ the same movements and steps but, for example, in the rave culture of electronic dance music, vast crowds may engage in free dance, uncoordinated with those around them. On the other hand, some cultures lay down strict rules as to the particular dances in which, for example, men, women and children may or must participate.
Dance is generally, though not exclusively, performed with the accompaniment of music and may or may not be performed in time to such music. Some dance (such as tap dance) may provide its own audible accompaniment in place of (or in addition to) music. Many early forms of music and dance were created for each other and are frequently performed together. Notable examples of traditional dance/music couplings include the jig, waltz, tango, disco, and salsa. Some musical genres have a parallel dance form such as baroque music and baroque dance; other varieties of dance and music may share nomenclature but developed separately, such as classical music and classical ballet.
Concert dance, like opera, generally depends for its large-scale form upon a narrative dramatic structure. The movements and gestures of the choreography are primarily intended to mime the personality and aims of the characters and their part in the plot. Such theatrical requirements tend towards longer, freer movements than those usual in non-narrative dance styles. On the other hand, the ballet blanc, developed in the 19th century, allows interludes of rhythmic dance that developed into entirely "plotless" ballets in the 20th century and that allowed fast, rhythmic dance-steps such as those of the petit allegro. A well-known example is The Cygnets' Dance in act two of Swan Lake.
Ballet reached widespread vogue in the romantic era, accompanied by a larger orchestra and grander musical conceptions that did not lend themselves easily to rhythmic clarity and by dance that emphasised dramatic mime. A broader concept of rhythm was needed, that which Rudolf Laban terms the "rhythm and shape" of movement that communicates character, emotion and intention, while only certain scenes required the exact synchronisation of step and music essential to other dance styles, so that, to Laban, modern Europeans seemed totally unable to grasp the meaning of "primitive rhythmic movements", a situation that began to change in the 20th century with such productions as Igor Stravinsky's The Rite of Spring with its new rhythmic language evoking primal feelings of a primitive past.
Social dances, those intended for participation rather than for an audience, may include various forms of mime and narrative, but are typically set much more closely to the rhythmic pattern of music, so that terms like waltz and polka refer as much to musical pieces as to the dance itself. The rhythm of the dancers' feet may even form an essential part of the music, as in tap dance. African dance, for example, is rooted in fixed basic steps, but may also allow a high degree of rhythmic interpretation: the feet or the trunk mark the basic pulse while cross-rhythms are picked up by shoulders, knees, or head, with the best dancers simultaneously giving plastic expression to all the elements of the polyrhythmic pattern.
The Punjab area overlapping India and Pakistan is the place of origin of Bhangra. It is widely known both as a style of music and a dance. It is mostly related to ancient harvest celebrations, love, patriotism or social issues. Its music is coordinated by a musical instrument called the 'Dhol'. Bhangra is not just music but a dance, a celebration of the harvest where people beat the dhol (drum), sing Boliyaan (lyrics) and dance. It developed further with the Vaisakhi festival of the Sikhs.
Ballet developed first in Italy and then in France from lavish court spectacles that combined music, drama, poetry, song, costumes and dance. Members of the court nobility took part as performers. During the reign of Louis XIV, himself a dancer, dance became more codified. Professional dancers began to take the place of court amateurs, and ballet masters were licensed by the French government. The first ballet dance academy was the Academie Royale de Danse (Royal Dance Academy), opened in Paris in 1661. Shortly thereafter, the first institutionalized ballet troupe, associated with the Academy, was formed; this troupe began as an all-male ensemble but by 1681 opened to include women as well.
Hip Hop originated in New York, specifically in the area known as the Bronx. It was created for those who struggled in society and didn't seem to have a voice in the community that surrounded them because of their lack of wealth. It helped those in the same situation come together and speak about difficult topics by using movement and feeling.
Dance teachers typically focus on teaching dance performance, or coaching competitive dancers, or both. They typically have performance experience in the types of dance they teach or coach. For example, dancesport teachers and coaches are often tournament dancers or former dancesport performers. Dance teachers may be self-employed, or employed by dance schools or general education institutions with dance programs. Some work for university programs or other schools that are associated with professional classical dance (e.g., ballet) or modern dance companies. Others are employed by smaller, privately owned dance schools that offer dance training and performance coaching for various types of dance.
