“Nothing is more exciting,” Charlie Chaplin wrote in his autobiography, “than to hear the tunes one has composed played for the first time by a 50-piece orchestra.” Many don’t know that Chaplin, though musically untrained, composed the quixotic, kinetic scores that carry his films. With eight different concerts that look at eight facets of Chaplin’s musicality, the Orchestre de Paris celebrates the man with the funny walk and the bowler hat. —L.J.
