in music, the basic attributes of sound are sound length, timbre, pitch and sound intensity. Only when these four basic elements are possessed and organized in a certain law can it be called music. Music score, for example, can't make sound itself, so it can't be called music. Therefore, whether it is the sound in nature or other forms of note recording, it must be expressed through the basic attributes of sound, and the appreciator also carries out aesthetic experience and feelings through the basic attributes. Music with strong timbre and long sound gives people a beautiful feeling. As an abstract art, music is not like sister arts such as painting, sculpture and dance. It directly affects the viewer through intuitive vision or synaesthesia, and it is mainly felt through human auditory organs. Therefore, from an aesthetic point of view, music is not dominant over other arts. For the aesthetics of music, people generally analyze it from the perspectives of the form and content of music, the performance of music, the creation of music and the function of music.
