Scratching comes from hip-hop turntablism, where DJs in the 1970s began moving vinyl records back and forth under the needle to create rhythmic, percussive sounds as part of a live performance. The technique became a signature of DJ culture and later spread into electronic music, radio intros, and video editing. Short scratch openers like this one are now widely shared on soundboards and in creator libraries because they work as a universal signal for a set starting, a beat dropping, or a scene changing, without needing any words.
