For Morellet, a work of art refers only to itself. His titles are generally sophisticated, show some word play, and describe the “constraints” or “rules” that he used to create them. Like other contemporary artists who use constraints and chance (or the aleatory) in their works (John Cage in music, the Oulipo group in literature), Morellet uses rules and constraints established in advance to guide the creation of his works, and he also allows chance to play a role in some of his compositions.
His rigorous use of geometry tends to create emotionally neutral work, and has placed him close to Minimal art and Conceptual art in his aims. He shares a particular affinity to the American artists Ellsworth Kelly, Frank Stella and Sol LeWitt.
