Theory art can also be referred to as conceptual art, as it revolves around the concepts and ideas behind the artwork rather than just the physical creation itself. Other synonyms for this term include experimental art, avant-garde art, and abstractionism. These terms all describe art that pushes boundaries and challenges traditional notions of what art should be. Additionally, theory art can be seen as a form of intellectual art, as it often incorporates research and critical thinking into the creative process. Other related terms include installation art, performance art, and multimedia art, which all incorporate various forms of media and often have conceptual elements as well.
