Miro was painter who seemed not to want to be defined in a particular genre. While influenced by VanGogh, Miro experimented with many forms of art. Early works expressed "humor." He turned away from the chaotic of the Surrealists and moved to more realistic work, working with light and color, to produce pastoral paintings. Hemingway noted that Miro's work was able to capture the essence of Spain: what was beautiful about it and what was missed when one was away. Later work included elements of fantasy. These elements were present in his work in the Surrealist movement in the 1920s. Reading about Miro's art, it seems safe to say that he never completely aligned himself with one form of art, but tried and was inspired by many forms and many places.
Because he seemed not to want to be defined by a specific genre, and in light of his experimentation, I would agree with "accessteacher" that "identity" was an important aspect of Miro's work.
