This word comes from the Latin “aleator,” meaning “dice player”, but the English meaning of “aleatory” refers to the nature of randomness, not necessarily the specific action of throwing dice. Aleatory games can involve dice, such as craps and Yahtzee, but other games of chance don’t require dice, including poker, roulette, and bingo. Another use of “aleatory” relates to art composition — random elements chosen during the production or performance of the art make up aleatory works. Jazz music would fit in this category.
