Compared with the historical style, the differences of the national style are more reflected in the temperament system, the tone scale, the specific rhythm type of "musical idioms" and the overall structure of music. For example, compared with traditional Chinese music, the timing and pitch of alto in European music are much more precise. Chinese music is not only much more free in terms of timing length, but also has many more "running tones" around stable pitch. Another example is that the harmonic function of the major and minor scales in European music does not exist in the music of other nations. These factors are related to the overall nature of the music acoustics structure and form the main discrimination basis for the differences in the styles of folk music.
