There are three main categories of music videos: performance-based, narrative-based, and concept-based. Performance-based videos simply show the artist performing the song, connecting the audience to the artist and lyrics. Narrative-based videos tell a story that relates to the song's lyrics, making the video more engaging for audiences. The example given is the music video for "Take On Me" by a-ha, which uses a romantic fantasy narrative and pencil drawings to illustrate the song.
