As I left the fiery domestic community life, "I feel sorry for myself silently, and if I lose something, I will be alone all day long". Looking at the natural beauty of Pingwu outside the window, I gradually began to like music. Since childhood, I like to play the flute and hum Sichuan Opera and Kunqu Opera. So I took advantage of the work-study program to go back to the past, learning violin with a German private music teacher and giving up studying economics. From 65438 to 0923, Wang Guangqi studied music theory in a conservatory in Berlin. 1927 was admitted to Berlin University to study musicology. Since he admitted to studying music, he studied music and musical instruments, introduced German music and European music to China, introduced Chinese classical music to Germany, and made a comparative study of Chinese and Western music. Although he became a monk halfway and lived alone overseas, his academic achievements and writing achievements are increasing day by day because of his desperate perseverance and realistic style, which has attracted the attention of the domestic music industry and surprised his old friends. 1934, Ph.D. in Classical Opera in China.

Since 1923, Wang Guangqi has written and published 16 kinds of music monographs, and published a series of music papers in Chinese and foreign newspapers (see now 16 China's music papers; Foreign music papers 14, 2 of which have been translated into Chinese). He has the ideal of awakening the nation with the help of music and completing the national cultural revival movement. He advocated that while sorting out ancient music, he should diligently collect popular folk songs, and then use the scientific method of western music to create "national music that can represent the Chinese nation." To this end, he conducted a comprehensive and systematic study of western music, and wrote monographs and papers in different categories to introduce to Chinese people. The works in this field mainly include: German music life (10 newsletter, 1923, 10,1,published in Shenbao), German music education, European music evolution, western music and poetry, and western music and poetry. He believes that China music "must be created by itself" and "cannot be replaced by western music", which shows a strong patriotism. To this end, he made an in-depth exploration of China music and oriental folk music. For the first time, he systematically adopted the method of comparative musicology to compare China's music and the music of some eastern nationalities with western music, and put forward the theory of dividing the music systems in various regions of the world into three systems: "China music system" (pentatonic system), "Greek music system" (heptatonic system) and "Persian Arabic music system" (three-quarters system). At the same time, he also preliminarily sorted out the historical materials of China's music laws in past dynasties, and put forward many theories. His works in this field mainly include Research on the Music System of the East and the West, Brief Introduction to the Music System of China, Similarities and Differences between Chinese and Western Music, Oriental Folk Music, Research on the Translation of Music Score, the Law of the Weight of China's Poetry, and the Music History of China. In addition, he has written many articles introducing China's music to western countries, including "Music of China" written for Encyclopedia Britannica and Encyclopedia Italia 1929.
