Is the essence of the whole work, usually divided into two parts-preface and human 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 vocal part sang the poem Ode to Joy by the German poet Schiller. But before the vocal part came on stage, music experienced the pain of playing instrumental part for a long time, 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, and Beethoven's real ideal kingdom was just around the corner!

After a series of preparations, the vocal part finally surfaced and began to sing "Ode to Joy". Ode to Joy, accompanied by passionate lyrics and rapid and magnificent melody, sings people's yearning for freedom, equality and fraternity. Of course, Beethoven did not copy Schiller's original poems, but made some abridgements and modifications with his own unique ideas to meet the needs of music. Under the mutual contrast of gripping lyrics and Beethoven's superman melody, under the solo, duet and chorus of four different voices, Ode to Joy has been sublimated, and those who appreciate it have gained unparalleled strength and spiritual support. At the end of the movement, this atmosphere is shown to the extreme, and the whole work ends in an extremely bright and brilliant scene.

Today, the Ninth Symphony in D minor is recognized as Beethoven's highest achievement in the field of symphony. It is said that Ode to Joy is the pinnacle of Beethoven's symphony, especially because the whole work seems to be a history of struggle between Beethoven's life and fate. The first and second movements of music are minor, which shows Beethoven's unfortunate early years. Pain and despair have been with him and tormented him. But he persisted, stubbornly fighting against fate. Slowly, the pain became calm (the third movement), so that at last he was completely relieved and got the real eternal final joy (the fourth movement). Struggle has always existed in Beethoven's works. Symphony No.9 in D minor, in particular, can give endless strength and hope to people struggling in the turbulent waves of pain and despair. At present, the best version is the version of wilhelm furtwangler Bayreuter Music Festival Orchestra and Choir, which was selected as one of the top phonograph records 100, the top 300 Japanese albums, and the Penguin Record Guide evaluated Samsung with flowers. And in 1997, it was recorded by EMI as the greatest recording of the century.

Fult Wengler had a profound understanding of Beethoven. He once said of Beethoven:

On Beethoven (from 1942 "Beethoven with global light") Beethoven has all the complexities of human nature. He really covers everything. He is not as fluent as Mozart, as energetic in architecture as Bach and as dramatic as Wagner. He has it all at the same time, including all its aspects. But when you observe him correctly, he is so unique! In the historical development of European culture, no other music contains lyrical and pure structure so naturally. Pure structure), combining rigidity with softness (softness &; Hardness) these completely different characteristics, but these characteristics are harmoniously linked with others and become a natural organic whole. No other music is as flesh and blood as Beethoven's music, just like our own bodies. In Beethoven's music, there is a sacred power to adapt it to the laws of natural organization. Beethoven's music is explosive, even ecstatic, reaching the extreme of human experience, but there is no deviation ... Anecdote: During World War II, Fult Ongler conducted Berlin Philharmonic to play a symphony on April 1942. This version is magnificent, but it is also called "Black Ninth Symphony" because it is played for the birthday of Nazi war criminal Adolf Hitler. After the war, Fult Wengler reinterpreted and re-recorded this work.
