Drama performance:

Drama actors generally create their own characters in the order of time and plot development. In this order, they strive to make the development of characters coherent, layered and There are ups and downs, and the front and back are harmonious and unified. In drama performances, what actors pursue is the beauty of stage performance. When drama actors perform on the stage, taking into account the distance from the audience and the audience's appreciation requirements, they must inevitably have appropriate performance in voice, language, body and expression. Exaggeration and even deformation, such as increasing the sound of stage lines, slow motion, etc., all need to be completed by the actors themselves, and the full and appropriate use of these characteristics constitutes the stage beauty of the drama actor's performance. These are opera stage performances that rely on the opera actors' lines, lyrics and vocals on the stage, plus body language, according to the arrangement of the script and the stage schedule derived by the director, and are completed in a coordinated manner.

Musicals:

Musicals are not just performances accompanied by music. It is not an opera, a comic opera, or a light musical, nor is it a vaudeville, a musical absurdity, or a nightclub cabaret. Both opera and musicals originated from religious music. Specifically, musicals were originally a differentiation of comic opera and operetta in opera, but eventually formed a completely different style from opera. The biggest difference between musicals and operas is the singing. If you can't hear the sound, don't observe the actors' mouth movements, and just rely on the stage and performance, it may be difficult to distinguish a musical from an opera. Most operas use bel canto singing, using a large number of arias and recitatives. The arias will accompany every dramatic turning point to push the whole play to a climax. Musical style, opera music is mostly based on classical music composition techniques based on more traditional orchestras. Occasionally, there are modern-style works that try to transcend this boundary, but most of them retain the way of thinking of classical techniques. However, the Chinese opera "The White-Haired Girl" is based on national singing methods, absorbs the advantages of opera singing and articulation, and adopts a singing method that combines folk songs, folk arts and operas to form an opera structure with its own unique singing style. Musicals are more free in the choice of music style, often involving jazz, rock and other popular music elements, and the orchestration often uses a large number of electroacoustic band instruments.

Puppet play:

Puppet play: A play in which actors manipulate puppets to act out a story. Also known as puppet show. Puppetry appeared in the Han Dynasty as a dramatic performance. A drama that uses puppets to act out a story. During the performance, actors operate puppets behind the scenes while singing and accompanied by music. Depending on the shape and manipulation techniques of the puppets, there are bag puppets, string puppets, stick puppets, wire puppets, etc. Puppetry is a form of theater in which actors manipulate wooden dolls behind the scenes.

To sum up, there are differences and distinctions between various drama types.
