Since the beginning of the twentieth century, ballet has continued to undergo modifications, keeping the best and drawing novelties from the changes that took place with the development of the world.

In the course of time, the costumes of the dancers and the form of the performances have changed. In addition to the traditional, world-famous performances, theater directors, with the participation of choreographers, create new shows, drawing, for example, on the achievements of modern dance.

Ballet also appears as an element of musical performances, accompanying other styles of dance. Classical librettos are modified and independently created music, such as the works of Frederic Chopin or Stanislaw Moniuszko, is introduced to create ballet shows.
