Among all kinds of folk songs, minor is a kind of music genre that basically gets rid of the restriction of practical function and is independent with expressive function as the main part. Its musical features are:
1 and minor tunes have smooth, soft, tortuous and delicate artistic characteristics. Its melody is rich in variety, which often combines the gradual mode with the jumping mode, the one-way lifting and bending, and the wavy melody line flexibly and skillfully, resulting in a ups and downs, diverse and unified melody.
At the same time, under the singer's long-term practice and processing, the connection between decorative melody, music and phrases is natural and logical, and he is very good at expressing those narrative and lyrical themes (such as Five Brothers Grazing Sheep, Drawing a Fan, A Prostitute Sorrow for Autumn and Birds with Five Rings). Most minor tunes are accompanied by instrumental music, and preludes, paragraphs and endings are added to make them more complete.
2. Minor is not influenced by external factors, but pursues the balance between harmony and flexibility of expression according to the inherent requirements of melody. Therefore, the rhythm of minor is regular but not rigid, and the sense of rhythm is distinct but not strong. Under the premise of not destroying the rhythm of lyrics and observing the rhythm law, we often use various rhythm patterns flexibly to make them dense and changeable, which has a strong sense of motivation.
3. The structure of minor is mainly single melody, and it pays attention to the regularity and symmetry inside the structure. The structure and function of phrases are relatively clear, and they are basically divided into two types: corresponding type and connecting type. Non-dual 3-sentence and 5-sentence structures are also common. In some areas, there are also "divertimento" composed of several singles (folk call it "major"). Regardless of the length, the internal structure of minor is based on the principle of correspondence and transition, forming a neat and balanced relationship. The last sentence often has a summary component and a sense of stability.
4. Different, but the interlining and cavity are repeated as they are, which becomes a powerful means to strengthen the unity of the whole work.
