The fixed nature of musical sounds means that in the European music system, "there are large 'spaces' and 'gaps' between sounds, and these 'spaces' and 'gaps' do not need to be filled with sound chambers." . Although the folk music works of my country's ethnic minorities that adopt the European music system also use accented sounds to some extent, such as vibrato, portamento, intensity changes, etc., they are related to the rich changes in the expressive intentions of the East Asian music system. essential difference. Regarding the progression of a single musical sound, the European music system "conceptually emphasizes the fixity of the sound."

The modal basis of the four-note sequence The modal basis of the European musical system is the four-note sequence containing two major second intervals and one minor second interval. There are three different styles of tetratone sequences, depending on the position of the semitone intervals in the sequence.

European music initially consisted of a four-note series of "medieval modes" (or "ecclesiastical modes"), and then gradually evolved into natural major and minor keys, harmonic major and minor keys, and melody major and minor keys. The most common folk music of China's ethnic groups that adopt European music systems are natural major, harmonic minor, melodic minor, Dorian mode and mixed Lydian mode.

The functional harmony of melodic thinking. The melodies of the European music system have the superficial meaning of functional harmony. These melodies are easy to match with traditional harmonies, and even folk artists who cannot read music can often use them with ease. This seems to indicate that in the long-term music practice, the melodic thinking of this music department has acquired functional harmony.

Equal rhythmic rhythm Functional equal rhythm is the main rhythmic feature of European music, with distinct strong and weak beats and regular alternation of strong and weak beats. Chinese national music belonging to the European music family is mainly characterized by rhythmic rhythm and rhythmic rhythm, and basically does not use the loose rhythm of the East Asian music family.

Polyphonic folk songs with rich multi-voice thinking and vertical lines in the texture are the most important phenomenon in European music. Many polyphonic folk songs in this music department show that their polyphonic textures have distinctive vertical and linear thinking characteristics.

Chinese folk songs belonging to various ethnic groups in the European music family are mostly monophonic, but from the only polyphonic works, we can find that they are close to the vertical linear thinking characteristics of European main-key music.
