The main features of impressionism music are as follows:

The creative principles and styles of classical music are rigorous and regular, while romantic music pays attention to the expression of emotion and the exertion of passion.

In contrast, Impressionist music does not directly depict pictures in real life through music, but more describes the feelings or impressions that those pictures give us, rendering a mysterious and hazy atmosphere and tone. In the form of music, short and irregular forms are often used to better reflect the relatively free characteristics of impressionist music.

Impressionist music was popular for a short time, and it was soon replaced by more radical and varied modern music. However, Impressionist music was a very important stage in the history of music development, and since then, music art has begun a fundamental change. Because of this, impressionist music has been paid great attention to, and its artistry and importance have been understood and recognized by more and more people.

Impressionist music works mostly focus on natural scenery or poetry and painting, highlighting the subjective impression or feeling of the moment; Break through the system of major and minor tones in music language and attach importance to harmony, texture and orchestration color; Good at expressing quiet and hazy, wandering and illusory artistic conception.

it was deeply influenced by impressionist painting and symbolist poetry at that time, and pursued to depict the blurred changes of colors and light and shadow around objects in an instant. Therefore, in impressionist music, harmony with colorful effects is far more important than melody.

Because the piano has the functions of harmony and exquisite tone change, and it can produce wonderful overtone effect in the ingenious combination of the hammer, strings and pedals, which can best express the sense of agility of the water-based sound, so it is very suitable for expressing the impressionist style. Not only that, impressionist music has gone beyond tradition in hearing feeling, concept consciousness and spiritual experience and has been updated in all directions.

as the founder of impressionist music, Debussy's creative characteristics are directly related to romanticism. Judging from the titles of his piano works, Debussy likes to pin his creation on the dream world, which is a major feature of romantic music.

Although Debussy's descriptions of nature abound, he doesn't use scenery to express his feelings like romantic music, but he is detached from things, wandering in the mountains and rivers, and entering a realm of selflessness and selflessness in the illusory artistic conception. Debussy is another master who digs the inner sound of piano after Chopin. He broke the bondage of tonality and opened up the microscopic world of piano timbre.

Compared with Debussy, the composer Ravel has great differences in piano music creation style. He is gradually getting rid of the constraints of impressionism aesthetics and returning to the more ancient and pure French tradition. Ravel enjoys the reputation as a master of orchestral orchestration, and his keen sense of color has greatly influenced his piano creation.

If Debussy mainly explores the performance potential and sound level from the piano itself, Ravel pays more attention to the color of piano sound from the angle of orchestra orchestration. His piano works are most famous for the suite Mirror, Ghost of the Night and two piano concertos.
