The term "art guided by" implies that art is being directed or influenced by someone or something. Antonyms for this phrase would be art that is unfettered, unguided, or uncontrolled. Art that is free-form, spontaneous, or improvisational might embody these qualities. Art that is not beholden to anyone's expectations or guidelines can be truly transformative and powerful. The concept of "art for art's sake" would also be an antonym for art guided by. This philosophy suggests that the true value of art lies in its ability to evoke emotional responses and make aesthetic statements, rather than fulfilling any specific goal or objective.
