Poetry music is generally folk music, mostly lyrical. Different from holding a party with a specific theme in a month, the main musical instruments are guzheng, dulcimer and pipa, so it depends on your personal grasp of the theme of poetry to set the emotional tone.
Secondly, a poem may be accompanied by several different styles of music, which all change with the change of poetic emotion. Whether it is warm, soothing or sad, and so on. There is no specific pattern for the score of poetry, as long as it sounds like there is no big emotional conflict.
In addition, Bandari's light music or English soothing tunes are used as the soundtrack for English poetry reading. In a word, practice makes perfect. Practice everything more. There is no routine to find.
All the above are my personal experiences, which come from some poetry reading experiences at school.
