What are the five keys in the Chinese national tuning system?

Pentatonic tuning is arranged in pure fifths in relation to intervals, and is of a tuning made up of five tones. Since this tuning is unique to our country, it can also be called the national tuning. The names of these five tones are: Gong, Shang, Horn, Zheng and Feather. The five tones have the following modes:

(a) The mode in which the Gong tone is the dominant tone is called the "Gong mode".

The Gong tuning, such as "Me and You"

(b) The Shang tuning is called "Shang tuning".

The Shang mode is known as "The Sun Comes Out in Joy"

(c) The mode in which the angular tones are dominant is known as the "Angular mode".

The angular mode is known as the "levantine mode", as in "Sister Gathering Bean Trees in the Field"

(d) The mode in which the levantine is the dominant tone is known as the "zheng mode".

The levy mode is called "Feather mode", as in "Song of the Revolutionary Soldiers Going to War"

(5) The feather mode is called "Feather mode".

Feather mode, such as "Kangding Love Song"

Level Properties

Level characteristics of five-tone tuning in the single-voice and polyphonic music, the stability and stability of the level. music differ in the stability and instability they exhibit.

In polyphonic music, the stability of the pentatonic scale is mainly determined by the harmonic configuration of the mode. The same tonality may be stabilized differently due to different harmonic configurations, so in polyphonic music, the harmonic configurations must be specifically analyzed in order to clarify which levels are stable.

In monophonic music, it is the 1st, 4th, or 5th level that is stabilizing. Level 1 is the main tone. It is the most stable. The 4th and 5th levels are four or five degrees from the main tone, less stable, but with greater support for the main tone.
