I found a question: Why do most ancient music in China only have five notes of 12356, while Japanese pop music only has five notes of 23467?

China's classical music is a five-tone symphony in the palace, while China's classical music is elegant and dignified.

The influence of old America on modern international music The blues scale is also the five notes of 12356, but it can present two completely different musical styles.

Japanese children and Japanese people also have their own music culture, which is also used by more than 5 (later). After the performance, it was very militaristic and had a far-reaching impact. So far, no matter how international the pop music made by Japanese pop people is, it can be considered that it is made by Japanese.
