Charles-Marie Widor was a hugely influential and venerated musician in his day, and his innovative organ symphonies are both a pinnacle of the repertoire and a testament to his creative and technical mastery of the instrument. These spectacular works are in the grand Romantic manner, but Widor was keenly aware of his musical ancestry, referring to music of the past such as Bach's St. Matthew Passion in the opening of the Third Symphony. The Scherzo of the Fourth Symphony is one of Widor's finest symphonic movements, exploring the organ's sonic beauties. The original E major Scherzo from the Symphony No. 2, which Widor subsequently replaced with a Salve Regina can be heard on Track 6.
