We often regret that Maurice Ravel has not left organ works. No doubt the organs of his time still very influenced by symphonic instruments did not suit his chiseled language. Fortunately, the transcriptions allow us to imagine what could have been the encounter with this colorful and unique king of the instruments. On the other hand, Maurice Duruflé is undoubtedly the most representative composer-organist of this trend called impressionism. His language is taken from both the Gregorian chant and the French universe sublimated by Maurice Ravel and Claude Debussy. Finally in Louis Vierne there is the obvious inheritance of the great romantics in the use of the form «symphony», but that is worked with a personal and personal language. His work is deeply linked to the great organ of Notre Dame de Paris, which he held until his death.
