Feather mode is a national mode with Shang mode as the main tone. The pentatonic feather mode consists of two C-type trisyllabic sequences. The pentatonic feather mode has obvious minor characteristics, and its minor nature is fully demonstrated by the minor degree of the feather palace and the minor degree of the feather number, which belongs to the minor color mode.
Feather mode is the most complete mode in pentatonic mode-the tonic and the upper three degrees form three degrees, and the tonic and subordinate tones each play an auxiliary role. Therefore, feather mode is closer to western minor mode than other pentatonic modes only in terms of function.
