Simon Frith proposed a theory in 1988 that categorized music videos into three types: performance, narrative, and conceptual. Performance videos focus on showing the artist performing the song, similar to a concert. Narrative videos tell a story that viewers can relate to personally. Conceptual videos do not have a narrative or show performance, but aim to convey a specific opinion or interpretation that can vary between viewers. However, Frith's 1988 theory may not accurately capture today's music videos.
