The air horn is a longtime staple of Jamaican dancehall and sound system culture, where DJs fire it to big up a selector or mark a heavyweight tune. New York DJ Cipha Sounds, a Hot 97 fixture from the early 2000s, made his air horn drops a signature part of hip-hop mixtape and radio culture. Clips of the blast now live on soundboards and in meme culture, where creators fire it over drops, entrances and punchlines. Three seconds is all it takes, which is why the horn has stayed in rotation for decades without losing its punch.
