Beethoven’s virus music is the virus of the third movement of the Pathetique Sonata.

The third movement, Allegro, C minor, 2/2 time, rondo sonata form. The theme of the movement is similar to the theme of the first movement. The beautiful melody contains unstable wandering emotions, seeming to be in an uncertain state of mind. It begins with a legato pouring down like raindrops. The main theme is filled with the brightness of youth and irrepressible vitality. Behind the laughter, there is a slight restlessness and turmoil. Although the theme of the minor part in the major key is clear, it also hints at the instability of the mentality with its rapid movement. Inabe expressed a truly strong and stable will in a declarative and firm tone. Several sections of this movement have Beethoven's usual "signature" endings, which give people a taste of the composer's confidence and chicness.
