His works Der Mond ("The Moon") (1939) and Die Kluge ("The Wise Woman") (1943),for example, he referred to as "Märchenoper" ("fairytale operas"). Both compositions feature the same "timeless" sound in that they do not employ any of the musical techniques of the period in which they were composed, with the intent that they be difficult to define as belonging to a particular era.
Carl Orff (1895-1982) One of the most important composers of modern season. Most famous work the Carmina Burana, Catulli Carmina. Carmina Burana was in fact so popular that Orff received a commission in Frankfurt to compose music for A Midsummer Night's Dream, which was supposed to replace the banned music by Mendelssohn. After the war, he claimed not to be satisfied with the music and reworked it into the final version that was first performed in 1964. Orff was reluctant to term any of his works simply operas in the traditional sense.
