To answer this question in a novel, many factors needed to be considered. Firstly, the creation of a song usually required a singer to have a solid foundation in music, including melody, rhythm, harmony, and so on. As a result, a singer's talent and achievements in music often required long-term training and tempering. Secondly, the singing and interpretation of the song was also an important factor. Singers needed to transform the composer's creative intent into their own performance style and express it to achieve better artistic effects. Therefore, singers and songwriters had their own strengths and limitations when it came to composing and performing. If you wanted to explain this problem in a novel, you might have to tell the story of a talented singer and a talented composer. Perhaps the singer had a good voice and could perform the song very well, while the composer could create a beautiful melody and lyrics for the singer. Under such circumstances, the singer and composer worked together to complete a moving song. In the end, the song became a classic and won widespread praise and fan base. The singer and composer also became famous figures in the history of literature. Of course, this was only a possible scenario. In a novel, it was necessary to create an interesting storyline according to the plot and theme, and use various rhetorical devices to show the character and fate of the character. Only in this way could the readers resonate and be pleasantly surprised during the reading process.
