① The lyrics of Xintianyou are characterized by two-sentence structure. Because its words are homonyms and are strictly restricted by phrases, it forms a stable form of two sentences and one paragraph. It takes metaphor as a means of thinking in images, chooses life and refines an artistic image with harmonious content and form. This is "seeking things and expressing feelings" or "touching the scene and feeling". In the long-term development of Xintianyou, these two traditional expressions have become their own fine traditions. Usually based on the previous sentence, comparison and the next sentence. The use of Bi Xing is naturally ingenious, appropriate and accurate. The sentence patterns are diverse, the rhythm is distinct, and the rhyming method is flexible and free. It is catchy to read and pleasant to sing. The length can be long or short, and two lines can be used as an independent poem. The organic combination of multiple lines and paragraphs can make the short chapter become a continuous Long song, showing richer and more complete content.
(2) Xintianyou is a lyric ditty. As mentioned earlier, because it is an outdoor song of Shan Ye, the environment is empty and not restricted by labor movement, so its melody is characterized by rough and unrestrained, melodious and high-pitched, which fully embodies the uninhibited character of people in northern Shaanxi. As Xintianyou sang, "An empty kiln can't sing". Of course, there are lingering, euphemistic, delicate and frank tunes in Xintianyou, just like the tunes that women miss their lovers.
(3) Xintianyou singing is not limited by tunes. According to the content of the lyrics and the mood of the singer, the same song can sing different feelings, which can be long or short, fast or slow. At the same time, each lyric can be matched with any tune, which shows that the tune of Xintianyou is not fixed.
