The words in the poem were originally used for singing, which is equivalent to the current lyrics. Is this sentence correct?

Yes! Poetry in a broad sense includes poems, words and songs. These creative forms have their own characteristics in content, form and genre. However, in the process of communication and absorption with music, the compatibility shown is beyond the reach of other literature. The word "poetry" itself contains "music", and we can also know that poetry and music are closely related. They promote each other, complement each other and blend with each other. Because China's poetry and music are closely combined, the so-called mixed art is formed, which is a wonder in the history of world literature and even the history of world music.
