First of all, in terms of music composition, China music is based on pentatonic music. The so-called pentatonic mode is a mode composed of five tones: Gong, Shang, Jiao, Qian and Yu, which is similar to "1, 2, 3, 5 and 6" in the present notation. Six tones and seven tones in national music are developed on the basis of five tones. Secondly, in the form of musical expression, China's music pays attention to the horizontal development of music, that is, the expression of melody.

China's folk music has its own great value, which is also an important factor for its bright future. The value of China folk music mainly includes: the aesthetic value of linear music. For thousands of years, China has formed its own unique "line" monosyllabic texture music expression system. Therefore, the national melody not only has indirect curvaceous beauty, but also has profound expressive significance.

Extended data:

The division of traditional music was first seen in the Introduction to National Music compiled by China Conservatory of Music, which can be divided into five categories: songs, song and dance music, rap music, opera and instrumental music. However, most colleges and universities incorporate song and dance music into folk songs in their teaching, so it becomes four categories: folk songs, national instrumental music, folk art music and opera music. National music, traditional music and folk music are three different concepts: national music includes traditional music and new music; Folk music is just a category of traditional music. And our national music is very rich, besides folk music, it also includes court music, religious music and literati music.
