atonalism

noun

1. (uncountable, usually)The school of atonal musical composition

   “No matter how melodramatic the story behind the music might be, most audiences won't buy atonalism; Arnold Schoenberg could have been devoured by escaped circus tigers while he was finishing the Variations for Orchestra and it would still get booed off the stage.”

   “As a young composer, he wandered for years in the desert of atonalism and then, following the example of John Cage, he detoured through the wilderness of music based on an aesthetic of randomness and anarchy.”
