What's the major key in music, huh?

Lol~ That's an interesting way of putting it!

What we usually call major keys are the major and minor keys in Western music,*** there are 24 of them, they are:

C major, a minor (no ascending or descending sign)

G major, e minor (one ascending sign)

D major, b minor (two ascending signs)

A major, #f minor (three ascending signs)

E major key, #c minor (four liters)

B major, #g minor (five liters)

#F major, #d minor (six liters)

#C major, #a minor (seven liters)

F major, #d minor (one descending)

ьB major, #g minor (two declining)

ьE major, c minor (three flats)

ьA major, f minor (four flats)

ьD major, ьb minor (five flats)

ьG major, ьe minor (six flats)

ьC major, ьa minor (seven flats)

This gives 30 keys in one ****. Of these, seven flats repeat with five ascending keys, canceling out two, six flats repeat with six ascending keys, canceling out two, and five flats repeat with seven ascending keys, canceling out two more, *** canceling out six keys, so 24 major and minor keys in one ****.

These major and minor keys can also be understood as you say, one above the other, but they are cyclic and not exhaustive.

China's folk songs usually do not use these major and minor modes of tonality, our folk songs have our own unique tonality, called the "five-tone tonality", only "Gong, Shang, Jiao, Zheng, Fei" that is, DO, RE, MI, SOL, LA, these five tones composed of. LA the five tones, unlike the Western modulation by DO, RE, MI, FA, SOL, LA, SI, seven tones, so you say Tibet, Shanxi side of the national song is not available to analyze the Western major and minor keys.
