Classical ballet in the context of "Paris Opera"

Ballet (French: [balɛ]) is a type of performance dance that originated during the Italian Renaissance in the fifteenth century and later developed into a concert dance form in France and Russia. It has since become a widespread and highly technical form of dance with its own vocabulary. Ballet has been influential globally and has defined the foundational techniques which are used in many other dance genres and cultures. Various schools around the world have incorporated their own cultures. As a result, ballet has evolved in distinct ways.

A ballet as a unified work comprises the choreography and music for a ballet production. Ballets are choreographed and performed by trained ballet dancers. Traditional classical ballets are usually performed with classical music accompaniment and use elaborate costumes and staging, whereas modern ballets are often performed in simple costumes and without elaborate sets or scenery.

Modern dance is a broad genre of western concert or theatrical dance which includes dance styles such as ballet, folk, ethnic, religious, and social dancing; and primarily arose out of Europe and the United States in the late 19th and early 20th centuries. It was considered to have been developed as a rejection of, or rebellion against, classical ballet, and also a way to express social concerns like socioeconomic and cultural factors.

In the late 19th century, modern dance artists such as Isadora Duncan, Maud Allan, and Loie Fuller were pioneering new forms and practices in what is now called improvisational or free dance. These dancers disregarded ballet's strict movement vocabulary (the particular, limited set of movements that were considered proper to ballet) and stopped wearing corsets and pointe shoes in the search for greater freedom of movement.

Ballet technique is the foundational principles of body movement and form used in ballet. It is an important aspect of ballet performance because ballet (especially classical ballet) puts great emphasis on the method and execution of movement. The techniques found in classical ballet are a framework for many other styles of dance, including jazz and contemporary ballet.

Aspects of ballet technique include alignment, which refers to keeping the head, shoulders, and hips vertically aligned. Turnout refers to completing movements with legs rotated outward; this promotes clean footwork, graceful port de bras (movement of the arms), and correct body positions, lines and angles. Other aspects of ballet technique include posture, toe pointing, keeping shoulders down, and pulling up, which combines proper posture and lifting of the muscles to increase turnout and enhance alignment and thus improve the quality of turns. Ballet technique is also used to exhibit ballon, the appearance of gravity-defying lightness, during leaps. Pointe technique is the part of ballet technique concerned with dancing on the tips of fully extended feet.

A ballet dancer is a person who practices the art of classical ballet. Both females and males can practice ballet. They rely on years of extensive training and proper technique to become a part of a professional ballet company. Ballet dancers are at a high risk of injury due to the demanding technique of ballet.

Free dance is a 20th-century dance form that preceded modern dance. Rebelling against the rigid constraints of classical ballet, Loie Fuller, Isadora Duncan and Ruth St. Denis (with her work in theater) developed their own styles of free dance and laid the foundations of American modern dance with their choreography and teaching. In Europe, Rudolf Laban, Emile Jaques-Dalcroze and François Delsarte developed their own theories of human movement and methods of instruction that led to the development of European modern and Expressionist dance.

Free dance was prolific in Central and Eastern Europe, where national schools were created, such as the School of Musical Movement (Heptachor), in Russia, and the Orkesztika School, in Hungary.

The Bolshoi Ballet is an internationally renowned classical ballet company based at the Bolshoi Theatre in Moscow, Russia. Founded in 1776, the Bolshoi is among the world's oldest ballet companies. In the early 20th century, it came to international prominence as Moscow became the capital of Soviet Russia. The Bolshoi has been recognised as one of the foremost ballet companies in the world. It has a branch at the Bolshoi Ballet Theater School in Joinville, Brazil.

The Mariinsky Ballet (Russian: Балет Мариинского театра) is the resident classical ballet company of the Mariinsky Theatre in Saint Petersburg, Russia.

Founded in the 18th century and originally known as the Imperial Russian Ballet, the Mariinsky Ballet is one of the world's leading ballet companies. Internationally in some quarters, the Mariinsky Ballet continues to be known by its former Soviet name the Kirov Ballet. The Mariinsky Ballet is the parent company of the Vaganova Ballet Academy, a leading international ballet school.

Giselle (/dʒɪˈzɛl/ jiz-EL, French: [ʒizɛl] ), originally titled Giselle, ou les Wilis (French: [ʒizɛl u le vili]; Giselle, or The Wilis), is a romantic ballet (ballet-pantomime) in two acts with music by Adolphe Adam. Considered a masterwork in the classical ballet performance canon, it was first performed by the Ballet du Théâtre de l'Académie Royale de Musique at the Salle Le Peletier in Paris on 28 June 1841, with Italian ballerina Carlotta Grisi as Giselle. It became hugely popular and was subsequently staged across Europe, Russia, and the United States.

The ghost-filled ballet tells the tragic, romantic story of a beautiful young peasant girl named Giselle and a disguised nobleman named Albrecht, who fall in love, but when his true identity is revealed by his rival, Hilarion, Giselle goes mad and dies of heartbreak. After her death, she is summoned from her grave into the vengeful, deadly sisterhood of the Wilis, the ghosts of unmarried women who died after being betrayed by their lovers and take revenge in the night by dancing men to death by exhaustion (a popular theme in Romantic-era ballets). Led by Myrtha, the Queen of the Wilis, they target Albrecht when he comes to mourn at Giselle's grave, but her great love frees him from their grasp. They gain their power in numbers as they effortlessly move through dramatic patterns and synchronized movements and control the stage with their long tulle dresses and stoic expressions, creating an ethereal atmosphere that builds as they gradually close in on Albrecht. By saving him from the Wilis, Giselle also saves herself from becoming one of them.
