The mysterious five-dimensional emptiness in the introduction is like the chaos before the beginning of the world, and the severe and powerful first theme gradually emerges from the chaos and darkness, like lightning splitting the sky, showing the image of hard struggle, full of great shock and tragic colors. This theme is first played by the string part in a low and depressing atmosphere, and then gradually strengthened until the whole band plays all the magnificent and powerful themes. The second theme is bB major, and woodwind instruments show a little sad atmosphere. The development department is G minor, and the tense struggle of stringed instruments leads the music to a climax. As soon as the composer came up, he expressed the ideological source of the whole work with serious and grand momentum. In fact, this is the theme repeatedly expressed by Beethoven in many works-struggle, which also reflects the inevitable process of struggle-hardship. Melody ups and downs, sometimes depressed, sometimes tragic, we seem to see the warriors constantly hitting the barrier, going forward, looking forward to victory. At the end, there is an enlightening foresight in the bass song. The first theme in D minor seemed to be suppressed in the past, but the melody suddenly appeared in an ascending scale, followed by stress, stood up tenaciously and ended the first movement in a tragic atmosphere.

The second movement: Allegro -D minor -3/8 beats.

Traditionally, it should be adagio, but there needs to be a dynamic scherzo behind the depressed background, so Beethoven broke this convention and used a fast movement and a huge scherzo style. The theme of the whole second movement is clear, exciting and full of motivation, which seems to give positive encouragement to the warriors who are fighting. It seems that people can see warm sunshine and blue sky in a cloudy battlefield at once, but people can still appreciate the hardships of living in it. It begins with an octave of percussion and is the main body of this fast and lively scherzo movement. It is said that this is Beethoven's feeling of suddenly moving towards light in the dark. The central theme of the three tones of the music has the characteristics of the Austrian folk dance Laendler (D major), which is harmonious and dancing, relaxed and delicate. But after careful taste, it is not difficult to find that at the end of the movement, the melody began to rush again, vaguely revealing a very uneasy atmosphere.

The third movement: Adagio-B flat major-4/4 beats-Variations on two themes.

Compared with the first two movements, this movement is much more quiet and serene to fully express warm feelings. Although the melody is gentle, it is very gentle. Berlioz, a famous French composer and music critic, rated this movement as "a great movement". The third movement has two themes, the first of which is full of meditation, with strong lyricism and philosophy, and the second is gentle (D major -G major) with strong romantic atmosphere. After the fierce fighting scenes in the first two movements, the third movement seems to be a brief calm in the war, but after the first theme was played for the third time, a fierce trumpet sounded, indicating that the revolution is not over yet.

Fourth Movement: Allegro -D Major -4/4 Beat

This long introduction to the last movement connects the themes of the three movements and is the essence of the whole work. Usually divided into two parts (overture and voice). In some records, the fourth movement occupies one track, and in some records, the overture and vocal solo, duet and chorus are divided into two tracks, but in fact, both of them belong to the whole of the fourth movement. Among them, the melody of vocal music is Spanish March written by the author himself, and the lyrics are German poet Schiller's poem Ode to Joy!

Instrumental part (overture):

Before the vocal part came to power, the music experienced a long painful experience (chanting and sighing) in the instrumental part, which included memories of the first three movements. This overture is powerful, resolute and thrilling. Then the woodwind slowly leads to the theme of Ode to Joy, as if a ray of sunshine broke through the dense clouds and sprinkled on the earth, and the whole happy theme gradually kicked off. Cello and double bass played the theme of happiness, and then viola, bassoon and violin were added, which means Beethoven's real ideal kingdom is just around the corner!

Main part (the orchestra is integrated with life):

Before the chorus appeared, Beethoven seemed to be "among the brilliant stars", but the band made a magnificent noise (the sound of the horn at the beginning of the movement), and then the baritone sang, "Oh, friends, don't make such painful sounds again!" After a series of preparations, the vocal part finally surfaced and began to sing "Ode to Joy"! Then, the music turned to bB major to make the singing more energetic. Then the band played several fugues, which pushed the music to the first peak. After the silence (in D major), the choir flashed the melodies of Ode to Joy and Workers Unite and merged them into two parts. After the second short silence, the choir sang: "Hug, millions of people kiss their brothers all over the world. At the end of the star is our loving and omnipotent father. Millions of people, can you kneel before him/can you feel him with you? " Go to the end of the star and find him. He must live at the end of the planet. "Finally, based on the theme of joy, the orchestra pushed the music to a brilliant ending.
