Arthur Honegger (hŭn´ēgər, Fr. ärtür ônāgĕr´), 1892–1955, Swiss-French composer, studied at the conservatories of Zürich and Paris. One of the group of Parisian composers called Les Six, he wrote music ranging from satire to intensely religious works that are marked by incisive rhythms and sharp dissonances, often the result of his use of polytonality. Besides Pacific 231 (1923)—the first of three mouvements symphoniques—his outstanding works are of a theatrical nature, such as ballets, the operas Judith (1926) and Antigone (1927, libretto by Jean Cocteau), music for films, including Mayerling (1935), and the stage oratorio King David (1921). He also set texts of Paul Claudel to music.
