Édition originale / The Original Edition This volume in the series “Les Éditions Originales Durand · Salabert · Eschig” contains Maurice Duruflé’s works for organ taken from the editions in Durand catalogue. The original engravings are reproduced, giving musicians a valuable record of how these major works were first published, whether in the composer’s lifetime or posthumously. With Olivier Messiaen, Maurice Duruflé formed part of an illustrious generation of composers who received the decisive imprint of Tournemire, either through his teaching or through his immense cycle L’Orgue mystiquer. In his catalogue organ music naturally has a major place. He did not force his own nature into any new aesthetic as he championed modality such as medieval music has codified it, asserting that “I have always inhabited Gregorian chant, which is obviously a fairly well-behaved language”.
