The formal beauty of music includes three aspects: basic elements, organizational means and rules of formal beauty. Among them, the law of formal beauty is not only a part of the composition of music forms, but also a key link between the basic elements of music and organizational means.

Specifically, the basic elements of music are melody and rhythm, including rhythm, melody, harmony, strength, speed, mode, form, timbre and so on. These basic elements combine with each other to form the common "formal elements" of music, such as rhythm, melody, harmony, strength, speed, mode, form and texture. The formal elements of music are the means of expression of music. Different types of music may emphasize or ignore some elements.
