Beethoven's works are essentially different from those of Haydn and Mozart. He is not only the master of classical music style, but also the founder of romantic music style. It can be seen from him that the social status of German and Austrian composers who grew up in the era of Enlightenment and the French Revolution was changing, and they had a more conscious understanding of the social status of free artists. His creations have a strong individualistic tendency and express personal experiences and thoughts. Beethoven developed the classical tradition in technique, especially his contribution to the sonata symphony suite. And he blurred the boundaries between movements or paragraphs, many works have the concept of sound-picture or title music, used human voices in symphonies, and modified and improved small genres, etc., which shows that he has adopted or It foreshadows certain characteristics of the Romantic music style.
