Contemporary ballet is a genre of dance that incorporates elements of classical ballet and modern dance. It employs classical ballet technique and in many cases classical pointe technique as well, but allows a greater range of movement of the upper body and is not constrained to the rigorously defined body lines and forms found in traditional, classical ballet. Many of its attributes come from the ideas and innovations of 20th-century modern dance, including floor work and turn-in of the legs. The style also contains many movements emphasizing the body's flexibility. George Balanchine is often considered to have been the first pioneer of contemporary ballet. However, the true origin of contemporary ballet is credited to Russian art producer Serge Diaghilev. Diaghilev wanted to bring an understanding of the arts to the general public. He created a program that combined all forms of the arts (painting, music, theater, and art) to present to the public. When this program had success in Russia, Diaghilev was inspired to bring it to a European audience by creating a new spin on classical ballet. He created Diaghilev's Russian Ballet Company, debuting the first show in 1909. However, Diaghilev was not a choreographer, he entrusted the evolvement of his creation to several well-known choreographers, one of them being George Balanchine. The style of dance Balanchine developed, which lies between classical ballet and today's contemporary ballet, is known by today's standards as neoclassical ballet. He used flexed hands (and occasionally feet), turned-in legs, off-centered positions, and non-traditional costumes, such as leotards, tunics, and "powder puff" tutus instead of "pancake" tutus, to distance his work from the classical and romantic ballet traditions. Balanchine invited modern dance performers such as Paul Taylor in to dance with his company, the New York City Ballet, and he worked with modern dance choreographer Martha Graham, which expanded his exposure to modern techniques and ideas.
