Some definitions given by philosophers are something I would definitely consider to be definitions for music, not for poetry. But to define poetry through definitions of music or musical feelings, is obviously cringe, a possible way is to give a "personal" one of the definitions for a universal musical beauty, such as a specific composition piece.
