The drum roll is a long-established percussion technique, traditionally played on a snare drum to signal attention before an announcement, a performance or a moment of ceremony. It became a familiar sound in circuses, talent shows and television, where it was used to heighten suspense before a result was revealed. Online, the same short roll is now a staple sound effect for short videos, streams and memes, because it instantly tells viewers that something is about to happen and makes the payoff feel bigger.
