Looking at the whole song, House of Flying Daggers shows the battle between Liu Bang and Xiang Yu in 22 BC. It can be roughly divided into three parts and thirteen paragraphs:

The first part is the pre-war preparation of the Han army. It includes five paragraphs: Battling, Blowing, Pointing, Arranging and Walking. At the beginning of the music, the pipa played a powerful chord symbolizing the sound of war drums in the high-pitched area, which presented us with an ancient battlefield scene with military camps and empty flags. The relaxation of music rhythm, the shift of mode, and the change of musical range, coupled with the various fingering changes that widely simulate war sounds such as drums, bugles, horseshoes, steps and guns, have produced dramatic effects: beating drums, clapping trumpets, shooting, blowing and opening doors ... vividly depicting the scene of the Han army dispatching troops before the battle.

the second part is a thrilling war scene in which the two armies of Chu and Han fought to the death. Including "ambush", "Jiming Mountain Little Battle" and "Jiulishan War", it is the core part of the whole song. Among them, "ambush" has a tense and horrible atmosphere. At this time, the speed is getting faster, the intensity is getting stronger, and the melody is increasing and decreasing. It is like a dark night, and the ambush is heavy, and the war is on the verge. The "skirmish" vividly shows the small-scale battle scene in which the two armies meet hand to hand. Then, the intensity was constantly strengthened, the melody was ups and downs, and the climax of the whole song-"Great War" began. The music used a variety of playing techniques such as "Sha", "Clip Sweep", "Double String" and "Push and Pull" to vividly and vividly render the whole battlefield atmosphere: thousands of troops, fighters, drums and swords.

the third part is the end of the Chu-Han War. It includes five paragraphs: Xiang Wang's defeat, Wujiang River's suicide, all the troops play the victory, all the generals strive for merit and return to camp victorious. The passage of "Xiang Wang Defeated" belongs to the nature of interlude in structure, and it has almost no melody at all. The musical homophony is repeated and gradually accelerated from slow to fast, mainly in a scattered rhythm, like the sound of horses' hooves, and then there is a rhythm that seems to be chasing, showing the scene of Xiang Yu and a few of his subordinates breaking through. The whole atmosphere of "Wujiang commit suicide" is low, and the tune is tragic and sad, which shapes the complex mood of Xiang Yu, a failed hero. At the end of this paragraph, after the "pressure" on the low string, it suddenly "falls" to achieve an abrupt end. The three paragraphs after "All the Armies Play Kai" describe various scenes after the victory of the Han army, which has been deleted by modern performers, and "Wujiang commits suicide" ends as the whole song.
