This paper starts with the ups and downs of pipa women's music rhythm and their life experiences, explores the deep-seated reasons for the touching sound of pipa, and analyzes why the author cries.

Bai Juyi's image of pipa girl in Pipa Xing has injected him with a strong subjective emotional experience. Poets and singers are elegant and secular; First, there is a superb spiritual realm, with wealth as dust and dirt as soil; One is pleasing colors, while I am busy eating delicious food and singing and dancing in Ding's home. Two people with different identities and positions are mixed up because of some similarity in their life experiences. The beautiful and melodious sound of pipa tells the ups and downs of her life, and also makes the poet deeply feel the sadness of impermanence in life.

The emotion of music is an important part of its artistic expression. The tension of lyricism, the intensity of priorities and the sense of rhythm of performers directly affect the transmission and pouring of characters' emotions. Judging from the performance of the pipa girl, the author simplified her two songs before she appeared and after listening to the poet's life experience. In the text, Bai Juyi took pains to describe the pipa sound in a complicated way. Exquisite and meticulous, ups and downs. Sometimes the spring breeze blows in Wan Ru, and sometimes the agitation is like a sword. It is obviously divided into three levels, which represents the singer's life stage full of laughter and pain. Of course, for the poet, this is also a true portrayal of his bumpy life.

From "... she turned the string shaft and tried to pluck a few strings" to "Nishang" and "Liu Yao", this is the prelude of Pipa girl's life. At this time, the music is slow and melodious, and the song is graceful. Although there is a deep atmosphere, there is also the joy of a small family. He learned pipa at the age of thirteen, and his talent was superb. Plus, he is young and beautiful, and naturally enjoys life secretly. Bai Juyi, a poet, became famous as a teenager, and his poems were famous for a while, which was greatly appreciated by dignitaries. It can be said that in the initial stage of life, both pipa girls and poets have a feeling of complacency.

Next, I heard more in silence than they heard in the sound. Pipa music changed from crisp and sweet to dripping, and became stagnant, depressed and heavy. Pipa girl experienced the madness of life, saw the prosperity and glory of life, and enjoyed the success brought by talent. "The silver comb inlaid with shells was broken by her rhythm, and the blood-stained skirt was ruined by wine stains." How obsessed and intoxicated, how confused and crazy it was! However, the chill of "spring flow under the ice" immediately struck, and the life of the pipa girl suddenly became barren and silent. Correspondingly, Bai Juyi also listened to music as a song of his life. From the active entry and innovation of young talents into the WTO to the collapse of the reform building and his demotion for a different party, Bai Juyi also experienced ups and downs in his life, and he was silent.

The following four sentences are the curtain call of Pipa girl's life. Music is passionate and excited, which is a power explosion after being suppressed for a long time, or a sudden eruption of a volcano that has been silent for a long time. Pipa girl was full of grief and indignation, and made an impassioned expression of the great joys and sorrows of life. This is the relief and helplessness after understanding life, seeing the world and suffering from the cold. Bai Juyi also took this opportunity to show that Sima Qing had more than a few tears after listening to the music.

In a word, the similarity between Bai Juyi and pipa girls in life determines that Bai Juyi will be happy because of the sound of pipa. It doesn't matter whether the identity of the pipa girl is real or fictional, or whether the pipa sound is high or low. What's important is that Bai Juyi completely integrated all his feelings about life and official career into the description of music, and lamented life with the help of its rhythm changes and various rhetorical devices.
