Improvisation and Ontology of Art

I am at explaining in which sense the notion of improvisation is highly interesting for the ontology of art. In the first part, I will criticize the widespread assumption of the repeatability of the musical work without transformation of identity and defend Conversational Improvisational Emergentism (CIE) as the specific contribution of improvisation to musical ontology. In the second part I will extend the scope of my investigation to art in general. While criticizing the principle “no evaluation without identification” and resorting in particular to Peter Lamarque’s and Joseph Margolis’ views about art ontology, I will propose a transformative theory of artworks, which is based on the thesis of the improvisational "nature" of artistic practices
