What does song mean in drama?

A song in drama is a musical composition with lyrics that is sung by one or more characters, usually in a stage production, musical theatre, opera, or film. Songs are often used to express emotions, advance the plot, or provide comic relief. They can be sung by soloists, duets, trios, or larger ensembles. Songs in drama often serve to enhance the emotional impact of a scene, create atmosphere, or provide commentary on the action. They can also be used to establish character, provide exposition, or set the scene. In some cases, songs may even serve as a form of dialogue, allowing characters to communicate with each other through music.
