Chopin is called "the piano poet". What do you think is the connection between piano music and poetry?

The greatest uniqueness of poetry and music is that they are both carriers of metaphor. The connotation of poetry and music can be said to be subjective and directionless, and the author's interpretation of the content of the work is the only authority. Before the author defines the work, all interpretations of the connotation of the work can only be said to be subjective guesses of the audience. This is also the universality of music and poetry, which are abstract works of art.
