The first part (including the first five paragraphs) describes the preparations of the Han army before the war, focusing on the magnificent lineup of the Han army. The sonorous rhythm is like an inspiring drum, and the passionate and high-pitched voice is like a bugle that shakes the valley, vividly depicting the unique drum on the battlefield. The second part (including six, seven and eight short paragraphs) is the central part of the whole song, which vividly depicts the fierce scene of the decisive battle between the Chu and Han armies. In the third part (including the last five short paragraphs), Xiang Yu committed suicide in Wujiang River after his failure in the first two paragraphs, and the low musical atmosphere was in sharp contrast with the previous climax. Among them, the melody of "Wujiang commit suicide" is tragic and tragic, which shapes the artistic image of Xiang Yu's generous elegy. The last three paragraphs describe the victorious posture of the Han army. In music, pipa uses the unique skills of flipping fingers and "stopping strings" to express scenes. Especially in the climax of the "Jiulishan War", a variety of pipa techniques were used to show the cries of thousands of troops and the earth-shattering decisive battle. Pipa is very good at simulating noisy sounds and is very infectious.
