A music video is a short film that integrates a song through imagery or video of the artists performing. Modern music videos are primarily used as marketing to promote music recordings. Music videos employ a wide variety of filmmaking techniques from animation and live action to documentaries and abstract forms. They can interpret lyrics visually or take a thematic approach, and some are simply filmed versions of a live performance. The goal is to further promote an artist's album and singles through compelling visuals along with the song.
