Quizplus · Accepted Answer

John Cage is credited with inventing a music of chance and random sound, which he called "aleatory music." Cage believed that all sounds could be music and that chance could be used to create new and interesting sounds that were unpredictable and spontaneous. He composed pieces using a variety of techniques, including the use of random numbers and coin tosses to determine the order and duration of the sounds. Cage's innovations expanded the definition of music and influenced many composers who followed him.
