"Qin Sang Qu" draws on the scale and rhythm characteristics of Shaanxi folk music, especially local opera, and forms the following two main style characteristics: the rhythm is expressed as two characteristic tones (also known as partial tones) in the diametrical heptatonic scale. ) The pitches of 4 and 7 are slightly different, the 4th is slightly higher (a microliter 4 microliters is equivalent to a quarter of a semitone), and the 7th is slightly lower (closer to a slight increase and 7 microliters is equivalent to a quarter one semitone), and according to the progression of the melody, these two notes are also wandering and unstable. They usually move in the direction of the 4th to the 3rd, and the 7th to the 6th. This tendency from instability to stability forms the unique charm of the music. The characteristics of the melody progression are: in general, the upward jumps forward and the downward progression. This kind of melody has a sharp contrast. Jumping up can produce exciting and active emotions; stepping down can produce euphemism and sadness. The music uses the melody for the interactive use of intermediate and jump-in. There is sadness in euphemism, and lyricism in excitement, so that people can fully appreciate the charm of Shaanxi music and feel The artistic effect of "hot ears and heartache" expressed by the music.
