Neoclassical ballet is usually abstract with no clear plot, costumes or scenery. Music choice can be diverse and will often include music that is also neoclassical (e.g. Stravinsky, Roussel).Apollo represented a return to form in response to Sergei Diaghilev's abstract ballets. Balanchine worked with modern dance choreographer Martha Graham, and brought modern dancers into his company such as Paul Taylor. More Info below.
