Both have their own advantages. Bel canto: that is, beautiful singing with beautiful song meaning. It is not only a vocal method, but also represents a singing style and a vocal genre, so it can usually be translated into bel canto and bel canto genre. One of the characteristics of Bel Canto is that it adopts a lower throat position than other singing methods, thus producing a bright, plump, relaxed and rounded sound quality with metallic color and resonance. Secondly, it pays attention to grammar. National Music: In a narrow sense, China's so-called national music refers to music with national characteristics, which can reflect the national culture and national spirit created by all ethnic groups who have lived and multiplied in this land of China for generations. Folk music in a broad sense refers to the music created by China musicians and the music with five colors of China. First of all, the origins of these two singing methods are different. National singing originated from China's folk operas, rap and folk songs, while Bel Canto originated from the religious music of the Western Renaissance. Bel canto is powerful, far-reaching, ethnic concentrated, lively and sweet. It's just a question of who one likes. China national vocal music and European traditional vocal music have some common rules in singing, but they also have many different and distinctive style characteristics. The technical comparison between the two singing methods, the plasticity of human body singing function, the influence of cultural differences between China and the West on music culture, and the experience in vocal music teaching, with a view to better combining the advantages of the two singing methods in vocal music teaching in the future, and establishing an open singing concept and flexible thinking method subjectively, we should not only carry forward the excellent national traditional culture, but also absorb and learn from the scientific singing method of Bel Canto.
