Radio art is the use of radio as a medium of art. Sound quality is secondary to conceptual originality. Radio art’s history demonstrates an evolution from the radio play through Musique Concrète and documentary radio to any manifestation of sonic art through the radio medium. Interestingly, its German name, Hörspiel, means radio play; It refers to a well-established often experimental medium. Similar to acousmatic music, Michel Chion’s term Cinéma pour l’Oreille is apropos.
