"Poetry" and "song" are often compared in Japanese literary history works, but they are two concepts. "Poetry" refers to Chinese poetry, that is, poetry written in Chinese and in accordance with China's poetic norms; "Song" refers to harmony songs. Harmony song was originally the oldest oral literature form in Japanese folk activities, and the earliest form was "duet" (called "Geyuan" in Japanese) when men and women fell in love in primitive times. This folk custom has been maintained, and aristocratic men and women in peacetime should also sing in chorus before marriage; After Heian period, this duet developed into a chorus competition, that is, a chorus (called chorus in Japanese), and thus developed into a chorus poem (also called couplet).
(わか Waka)
This is a Japanese poetic style.
This kind of Japanese poetry is for China. The earliest poems in Japan were written in Chinese characters, some with meanings and some with sounds. On this basis, poems with Japanese characteristics came into being. Because Japan is called the Yamato nation and has written poems to sing, it is called chorus.
Chorus includes Long song, short songs, short songs, Legato songs, etc. With the passage of time, more and more people write short songs, and now they account for an absolute majority. Because of this, although people still call it chorus, it mainly refers to short songs. Singers also refer to people who are mainly short songs.
