Aleatoricism is the creation of art by chance, exploiting the principle of randomness. The word derives from the Latin word alea, the rolling of dice. It should not be confused with either improvisation or indeterminacy. An example of aleatory writing is the automatic writing of the French Surrealists involving concrete dreams, forgotten memories, and inexpressible propositions. There are many recent writers whose work proceeds from aleatory composition, including Jackson Mac Low, John Cage, and Joan Retallack. Luke Rhinehart''s novel The Dice Man tells the story of a psychiatrist named Luke Rhinehart who, feeling bored and unfulfilled in life, starts making decisions about what to do based on a roll of a die. Charles Hartman discusses several methods of automatic generation of poetry in his book The Virtual Muse.
