Music has many functions such as entertainment, education, aesthetics and cognition. Scholars all over the world attach great importance to the educational function of music. Soviet educator Suhomlinski said: "Music has an important influence on the minds of teenagers, and music is the source of thinking ability; Without music education, it is impossible to achieve satisfactory intellectual development. "Confucius, a great educator, thinker and musician in China, ranked' Li' as the first of the six arts and' Le' as the second, which formed the traditional optimism of rites and music in China, and made China once a highly civilized country in the world. Students all know that the entertainment function of music can relieve people's troubles and fatigue and make people relaxed and happy. This is the power of music. Students should also know that for everyone, music is not just entertainment, and entertainment music can not fully reflect the essence of cultivating character and quality. The highest purpose of music is to reflect society and promote social progress. As Beethoven said, "Music should stimulate the generation of human spirit. "People's musicians Nie Er and Xian Xinghai attach great importance to the education and fighting function of music. Nie Er's works, such as March of the Volunteers, Song of the Dockers, Song of the Girl under the Iron Shoes and Song of the Road, reflect the strong determination of the people of the whole country to rise up against Japan. For the first time, they described the sufferings of the working class in China under the oppression of the three mountains and the spirit of resistance, which played a fighting role as the horn of the times. Xian Xinghai's Song of Salvation, I'm afraid I can't resist, Chorus of Production, The Yellow River Cantata and other works show the firm belief and revolutionary fighting spirit of the people of China. Students can be inspired and educated by singing these works. Therefore, the educational function of music lies in promoting the healthy development of people's thoughts and moral concepts through emotional activities, purifying the soul and cultivating sentiment. School music teachers should guide students with healthy and progressive music, so that music can play its due role in cultivating talents with all-round development in morality, intelligence, physique, beauty and labor. The vulgar music distorts students' aesthetics, makes them unable to distinguish beauty from ugliness, and pollutes their minds, which should be highly valued. Of course, this also proves the educational function of music from the opposite side. In a word, music can educate and entertain.
