The power of music is huge. A good musical work can impress the audience through its unique musical image and musical language, making it intoxicating, imaginative, or exciting. In ancient times, people knew that music had a significant impact on the formation of people's moral concepts. The famous Greek mathematician and astronomer Pythagoras also studied music. He said: "I blend various tones together to turn all kinds of inexplicable jealousies, impulses and other shortcomings into virtues." Indeed, a person can If he devotes all his thoughts to Mozart's bright and cheerful music world, or immerses himself in Beethoven's heroic music full of defiance, he will become kinder and purer. Music is a clarion call that inspires people to fight hard. There are many examples of this in the history of Chinese and foreign music. In ancient my country, when two armies were fighting, both sides used drums to cheer up. They should use rhythmic drumming to boost the morale of the soldiers, charge into the battle, and go all out. During the Eastern Zhou Dynasty, Guan Zhong, the prime minister of Qi, was a talented politician and military strategist. He was also proficient in music and could compose music. The Huzhu Kingdom often invaded the Qi Kingdom. In order to eliminate the foreign invasion, the King of Qi and Guan Zhong led troops to attack the Huzhu Kingdom. Encountering a high mountain, it was difficult for chariots and horses to cross. Guan Zhong composed a "Mountain Song" and asked everyone to sing. Soon after the song started, the leading team and chariots quickly rushed up the mountain. When going down the mountain, Guan Zhong composed another "Song of Descending the Mountain". When the soldiers sang this song, everyone was in high spirits and quickly crossed the mountain and ran towards the Huzhu Kingdom. Music can also demoralize enemy troops. Liu Bang of the Han Dynasty and Xiang Yu of the Chu Dynasty were fighting in Gaixia. Liu Bang's counselor Zhang Liang knew that the Chu army had been fighting for years and was homesick for a long time, so he came up with the clever plan of "dispersing Chu with tragic songs". He taught the soldiers to sing the sad songs of Chu. When Xiang Yu's soldiers heard the songs of Chu, they felt homesick, and they all dropped their weapons and fled. "La Marseillaise" by French composers Rouge and Fachauer has become a powerful weapon to inspire the fighting spirit of revolutionaries in all European revolutions. And the "Internationale", which has been inspiring the proletariat to charge into the old world for 100 years, makes all reactionaries tremble with fear.
