In addition to fixed-scene poems and puppet shows, music accompaniment and oral dialogue are the most related to the front and back scenes. In addition to puppet or puppet performances, the performance of Allegro and Adagio by the backcourt personnel's music, ventriloquism and coordination with the frontcourt's civil and military plots is the skill of a puppet troupe. There is a saying in the puppet show that "three points in the frontcourt and seven points in the backcourt" just shows the importance of the backcourt for music or oral dialogue to express the essence of puppet show.

In terms of backcourt music, traditional puppet shows are accompanied by two musical styles: Beiguan and Nanguan. Backcourt can be divided into literary field and martial field according to different musical instruments. Martial field refers to percussion instruments with only rhythm but no pitch, and literary field refers to the performance of string-pulling, plucking and wind-playing instruments with pitch changes.

If we make a detailed breakdown, the martial arts instruments include gongs, small gongs, small drums, drums, banknotes, cymbals, clappers, and so on, while the literary field includes erhu, suona, clappers, yueqin and flute. [6] And this type of music can be subdivided into Shengdan Opera, Shenchang Opera, Martial Arts Opera, Liantai Opera, Zhezi Opera and Boxing Opera. After the mid-2th century, the background music gradually changed, such as the introduction of Beijing opera background music, the use of western instruments and music, live singing by singers, or playing electronic music on tapes and so on.

A colloquial master who speaks the local language of Minnan or Taiwan Province can be described as the soul of Budai. In the performance of puppet show, the master of oral dialogue in the backcourt arranged the dialogue and dialogue of all the characters in the play, and was often the only starring actor in the puppet show. It is because of the success of the performance that the oral leading role of a professional storyteller must have the skills of imitating the sound quality of different characters, different speech styles and even different local accents. As an example, a popular master of oral English must also have profound literary attainments and musical attainments, and must be able to distinguish the five tones of roles with different personalities, plus the eight tones and seven emotions of emotional expression, and the oral English of other basic roles and so on. From this point of view, a master of oral English should at least have the ability to dub 28 different emotions and roles. In addition, the puppet show's very special poetry recitation or the rare monologue recitation in the play is also related to the quality of a play.
