Lightsabers are the glowing energy swords of Star Wars, first seen in the 1977 film, and their distinctive hum and clash have become one of cinema's most recognisable sound signatures. Short clash clips like this one circulate widely because they are instantly understood without context, letting fan filmmakers, gamers and meme creators suggest a duel in less than a second. As Star Wars has continued through new films, series and games, the sound has stayed in constant use for edits, parodies and reaction videos.
