1. Aesthetics divides artistic beauty into several types of music according to the beauty of different expression methods, which belong to time art (according to the way of existence), auditory art (according to the way of perception) and performing art (according to the way of creation)

2. From the aesthetic point of view, please analyze the practical significance brought by this music. That is to say, the "artistic conception" conveyed by the music lies in what kind of scene the music depicts (the image inside the intuitive and static real image), what kind of feeling this scene brings to you (the image outside the image of active life), and what kind of thinking this feeling has caused (this kind of thinking is a deeper philosophical thinking, don't stay on the surface of the music, but dig deeper into the intangible image based on the previous two layers).
