Extended information:

Beethoven's life experienced the drastic changes in European society before and after the French Revolution. His works are the product of the combination of the times and personality. He greatly expanded the ideological content of symphonic music, making it a genre that directly reflects social changes, and the range of expression of the piano was also greatly enhanced.

The expansion of content leads to innovation in expression techniques: it breaks through the traditional formal structure, uses motivational themes and develops dynamic musical ideas, giving the music extraordinary momentum and power; it is based on function The systematic voice change system has become a characteristic of his harmonic style.

Flexible off-key modulations and large contrasts in rhythm and intensity play an important role in portraying conflicts and dramatic developments. In addition, the use of counterpoint, the combination of band sounds, and the writing of piano music all have distinctive characteristics.

Beethoven’s symphonies can be divided into the following categories in terms of content: first, heroic and dramatic, which is the most basic aspect of his creation, such as the third, fifth, and fourth symphonies. Nine symphonies; second, those that are customary and lyrical, such as the first, fourth, and eighth symphonies; third, those that are mass and dance-oriented, such as the seventh symphony.

Beethoven's string quartet finally established its serious ideological and emotional, lyrical and philosophical genre. Especially the string quartets of the late period express the composer's style characteristics, profound psychological portrayal, and the free combination of images of various personalities.

Beethoven’s vocal works are relatively small in number, but they are of great significance and value. "To My Lover in the Distance" can actually be said to be the first romantic vocal suite. Most of his songs are simple descriptions of daily life.
