This fifth Symphony of Tchaikovsky, and its younger and still more emotional brother, the ' Pathetic', appear to be two of the most popular among the symphonies written since Beethoven. The Fifth Symphony in E minor is too well known to need close description. Those to whom it is not yet familiar should first know that there is a ' Motto ' theme that binds the four movements together. It is the chief subject of the sombre Introduction that leads to the swinging first movement ; it is noisily declaimed and abruptly sounded at the climax of the romantic second movement; near the end of the Waltz which forms the third movement it enters, in the bass, with a suggestion of mockery ; and as the spirited fourth movement works to a climax it is thundered out triumphantly in the major key.
