Poetry without music is like a coral reef without fish; they belong together and one complements the beauty of the other.
Define music?
Poetry was originally developed to keep track of history. It has melody and song built into it.
That said, “song” and “poetry” are two separate arts. Sometimes united, sometimes not. But “poetry” still stands alone as its own art.
And the great poets of the 20th century often had a far more melodic and lyrical quality than the most praised pop music that was hailed as poetry.
