Music videos promote an artist's music and entertain audiences. They typically last 3-4 minutes and can include live performances and/or narratives that match the rhythm and pace of the song. Music videos use various elements like performances of the artist, narratives telling a story, themes depending on the genre, and symbols to build meaning. They are stylish for their time and cut to the beat, intercutting between performances and images to produce meaning. Differences exist between how male and female artists present themselves, with men often singing toward the camera and women sometimes portrayed as objects of erotic gaze.
