Codes and conventions in music videos help construct meaning and include both technical and symbolic elements. Technically, elements like camera angles, sound, editing pace and genre influences are used. Symbolically, facial expressions, body language, costumes and props help viewers associate meaning. Codes and conventions ensure the visuals match the lyrics and help classify videos into genres like pop, which features choreographed dancing, or rap, which sometimes sexualizes women. Narratives in music videos can be linear with a clear beginning, middle and end, or fragmented with no obvious narrative structure. Performance styles also vary between genres, with pop videos often featuring artists in storylines rather than live performances.
