Of the five movements the second movement was written first, the first movement was written next, then came the fourth movement, then the third movement; and the last - fifth - movement was indeed written 'at last'. Movement I is a Passacaglia in C, a slow overture in the grand style. II was written originally for two pianos eight years before the rest, and incorporated as the second movement of the symphony. It is a brisk and jazzy dance. Movement III is a short, passionate page about somnambulism, full of dynamic contrast, and coming from afar. Movement IV is a farewell to France. Movement V is a long and fast Rondo - a Concerto for Orchestra all by itself.
