Other synonyms include evocative music, illustrative music, and narrative music. Some pieces of descriptive music are also classified as tone poems or programmatic symphonies, which are large compositions that follow a specific narrative or theme. Film scores can also be considered descriptive music, as they often seek to enhance the emotional impact of a scene or convey a specific atmosphere.
