Louis Vierne, one of the great concert organists and composers of the 20th century, is best known for his organ works. In each of the six Symphonies for Organ, Vierne explores a method of generating a symphony from just a few themes. He once stated that he was far more attracted by musical thematicism than by tone colour. Born virtually blind, Vierne showed an early aptitude for music. His works are said to reflect the vast and decorated architecture of Notre Dame in Paris.
