When I hear the sound of Matsutani, I wave my hand at will.
The sound of the bell rang, and it turned into a frosty bell. My heart was quiet, as if it had been washed with water.
Unconsciously, dusk enveloped the castle peak, and the autumn clouds were bleak, covering the dusk sky.
Brief analysis: "Luqi" was originally the name of a piano. In the Han Dynasty, Sima Xiangru had a piano named Luqi, which was used to refer to expensive pianos.
The first two sentences write the musician in a very stylish way, expressing the poet's admiration for him. "Waving" is the action of playing the piano. Ji Kang's Fu Qin: "Boya waves and the bell listens." The sentence "I heard him in Qingxi" implicitly uses the allusion of "high mountains and flowing water" (see Liezi Tang Wen); The phrase "the bell rings into the frost" is also used in allusions. Frost bell talks about Shan Hai Jing, Zhongshan Jing: "Fengshan ... has nine bells, which is to know first frost." Guo Pu's note: "The first frost rings, so you know what it says." The word "frost bell" points out the season, which echoes the following "cloudy autumn and sky" "Reverberation into frost bell" means that after the music stops, the reverberation lasts for a long time and blends with the temple bell at dusk.
In Liezi Tang Wen, there is a saying that "reverberation lingers for three days", and Su Shi used "reverberation" to describe Dong Xiao's reverberation in Qianchibi Fu.
Li Bai's poems describing music are characterized by paying attention to the feelings when listening to the piano and the emotional communication between the player and the listener.
