There are 46 major songs listed in "Jiaofang Ji", among which "Nishang Yuyi Song" is the most famous. "Nishang Yuyi Song" is referred to as "Nishang", and the music belongs to French music among the big songs. The structure of Faqu is the same as that of Daqu. Its characteristic is that the tune and the instruments used are more similar to the traditional Han music "Qing Shang Yue". It is mainly based on Shang tune, and most of the accompaniment instruments are old instruments from the Central Plains, and chimes and chimes are added. It is said that "there were French music in the early Sui Dynasty, and its music was clear and elegant" ("New Tang Book? Rites and Music"). In addition, Chen Yang's "Book of Music" records that "Faqu originated in the Tang Dynasty, and the southern sound originated from the Shang Dynasty of the Qing Dynasty." The music of "Nancy Clothes and Feather Clothes Song" was conceived and composed by Emperor Xuanzong of the Tang Dynasty. Later, he partially absorbed the Indian "Brahmin Song" presented by Yang Jingshu, the military governor of Xiliang, and then compiled it into the dance "Nice Clothes and Feather Clothes Dance". Bai Juyi's "Song of Neon Clothes and Feather Clothes" describes the beginning of this music and dance as "the chimes, flutes, zithers and flutes are passing each other, and the sound of percussion and bombs is meandering. The clothes are not moved in the six prefaces, and the clouds on the balcony are lingering but not flying." It can be seen that at first it was a free sequence, with instruments such as chimes, xiao, zither, and flute sounding one after another according to the different textures of gold, stone, silk, and bamboo. They were played in this way several times. "The clouds are careless and do not fly" shows its beauty, and makes people "love the time when the colorful clothes are not taken". In the middle sequence, the dance starts, "Floating and whirling back to the light snow, sending off the swimming dragon in a beautiful way. The willows behind the small hanging hands are weak, and the clouds are about to come to life when the train is slanted." The initial dance form of "Neon Clothes" is known for its flexibility, and its imagery can be seen in "Returning to the Snow" and "Wandering Dragon". The "Willow Powerless" and "Clouds Desire to Live" are really wonderful rhythms, and then unfold into the next chapter. "The moth is so arrogant, the sleeves of the wind are low and affectionate. When Shangyuan ordered the servant girl to attract Calyx, the Queen Mother waved her arms to Feiqiong." Calyx and Feiqiong are both fairies, and the fairy sentiments in the heavenly palace in "Neon Clothes" are all there Among them, after all these images are full and full of dance, it is the "breaking" of the big song. The scene is "the complex tones are repeated twelve times in sharp rhythm, and the dancing beads shake the jade with clang". This is completely a climax of passionate dance, with rapid rhythm, complex melody, and the resonance of each other, which is sonorous and powerful. Generally, big songs end with a quick beat, but "Nishang" ends with a long lead. It is said that "the flying luan dances but folds its wings, and the croaking crane ends with a long lead." During the Yuanhe period in Chang'an, when Bai Juyi was appointed as the School Manager of Jixian Academy, Zuo Shiyi, and Hanlin Bachelor, he saw with his own eyes the scene of "Dance of Colorful Clothes and Feather Clothes" performed in the palace, and he had the above description of the poem. It is no wonder that the poet "singed and danced countless times" , "My favorite is the "Neon Shang" dance."
