How to evaluate dvorak's Ninth Symphony from the New World?

There is a natural tendency in people's psychological activities: when K time keeps a state, people have a desire to change. This tendency to change and contrast is called psychological "seeking the opposite sex". It is usually formed after a stimulus or a mental state has been maintained for a period of time. When the three themes of the first movement are repeated 12 times, the exciting reappearance of the unfolding part is retained. After the magnificent sound, the end of the whole movement is over, and a psychological demand for "seeking the opposite sex" is getting stronger and stronger. At this time, the second movement, with its extremely moving adagio, lyrical and beautiful poems, and the bleak atmosphere depicted by a series of gloomy wind instruments and chords, was blown out by the British sound tube with a moving melody, soft as velvet, and a sad and sobbing string-changing sequence, just like the night fog in the depths of the soul. This gentle melody is in sharp contrast with the brilliant and powerful sound at the end of the first movement in terms of speed, strength and rhythm. Make people's needs change and meet the psychological needs of comparison. At the beginning of the middle section, the mood is a little excited, while the second melody in the middle section is quiet, alternating with the previous melody; The third melody jumps briskly, bringing a ray of dawn to the gloomy atmosphere of the movement. Soon, this joyful mood was interrupted by the harsh trumpet and trombone, and the theme material of the first movement appeared. It was so solemn and powerful that it formed the climax of the movement. When the theme reappeared, the music did not return to the original sadness. Because the violin is added with a mute, the music becomes softer and more hazy. At the end, the gloomy chord in the introduction appeared again, as if it were a plaintive moan, which formed a further contrast with the first movement. Someone once commented that this is one of the most beautiful adagio movements in all symphonies in the history of music. From a psychological point of view, this most beautiful feeling is actually produced by the contrast between the two movements and the theme in them. In this series of comparative changes, people's psychology is satisfied and solved in the psychological expectation and contradiction formed in the first movement, thus producing a comfortable and natural feeling and a pleasant aesthetic experience.
