Law & Order premiered on NBC in 1990, created by Dick Wolf, with music by composer Mike Post. The opening sting, often written as dun dun, became one of television's most recognisable audio logos, marking scene changes throughout the long-running franchise and its spin-offs including Special Victims Unit. Parodied for decades on sketch shows and later in memes and short videos, it now works as shorthand for interrogations, accusations and courtroom drama even among viewers who have never watched a full episode.
About this sound
The iconic Law and Order intro sound effect, the two-note dun dun sting from the NBC crime drama, used for dramatic reveals and mock courtroom moments.
This is the famous two-note percussive sting that opens Law & Order, a deep, echoing dun dun built from layered orchestral hits. It lasts only a few seconds but lands with instant authority, signalling a shift to a new scene, a serious accusation, or a verdict about to be delivered. The sound is clean, tense and unmistakable, with a hollow metallic edge that mimics a jail door and a gavel at once. Listeners recognise it immediately even without the narrator, and creators rely on that recognition to add weight, irony or mock-serious drama to an ordinary moment.
