Music videos often represent the lyrics of songs through images that either illustrate, amplify, or sometimes contradict the lyrics. Certain genres are associated with common conventions and iconography, such as rock music featuring guitars and group performances. Additionally, the visuals in a music video are typically edited to match the beat, pace, and emotion of the song. Music videos also commonly employ voyeurism through the use of techniques like handheld cameras and representations of looking through mirrors or screens. Record labels often demand that artists make direct eye contact with the camera through many close-ups to make the audience feel the video is aimed at them personally.
