Music videos can promote an artist's music and image in several ways. They often include a performance of the song by the artist, which may take place in unusual locations. Music videos also sometimes tell a narrative story or use symbolic imagery to represent the themes of the song. Women are sometimes portrayed in an objectified or sexualized manner in music videos according to theories like the male gaze. Common types of music videos include performance, narrative, and spectacle videos which may address the viewer directly or follow a story structure.
