Practice and discussion of national folk music in teaching

China folk music is an integral part of the traditional culture of all ethnic groups. As the ecological landscape of national culture, it attracts anthropologists, national musicians and many artistic aesthetic pursuers all over the world. However, the significance of national folk music lies not only in aesthetics, but also in people's behavior of exchanging feelings and information. It undertakes many social functions such as imparting knowledge, etiquette, religious activities, interpersonal communication and so on, and is the "spiritual bond" of the nation. Over the years, when the national folk music was separated from the original cultural ecological environment and entered the professional school education, the whole national folk music culture gradually divided into systematic knowledge structures, such as melody, scale, mode, rhythm, texture and so on. However, the disciplinary nature of national folk music teaching also determines that it is a theoretical course that pays attention to the investigation of actual music life and absorbs and accumulates rich on-site information from it. How to guide students to use scientific theories and effective methods for investigation and practice in the teaching of national folk music? Generally speaking, teaching should start with perceptual materials and combine sensibility with rationality, that is, cultivate students' temperament with rich national music, gradually cultivate students' national psychological quality in a subtle way and enhance students' love for mother tongue culture; Encourage students to go out of the classroom, go deep into the people, appreciate the beauty of traditional music in China, and personally collect all kinds of music research materials, so that they can make continuous scientific exploration in theory and practice.
