Gesamtkunstwerk (total work of art)

Explanation:

     When Whilhelm Richard Wagner, a 19th-century German composer, spoke of “total work of art” in his work titled “Das Kunstwerk der Zukunft” 1or “The Work of Art of the Future”, he proposed the convergence between artistic languages producing a spectacle. complete. For the composer, the arts should not be isolated from each other, since man is a being of language.

     His "total work of art" was considered a global theory for all arts, going against the limits imposed by art until the nineteenth century, which considered only the artistic languages separately.

He then developed a pioneering project: he built a building designed specifically for his operas, creating a unified entity between the orchestra and the stage.

He even seemed to be predicting the emergence of what we today call hybrids.
