The word redoble is Spanish for a drum roll, a technique where a drummer strikes a snare drum rapidly to sustain a continuous rattling sound. Rolls like this have long been used in military bands, processions, circuses and theatre to signal that an announcement, entrance or daring feat is coming. Short digital versions labelled as FX clips spread through video editing libraries and soundboards, where editors reuse the same tense build for reveals, unboxings, challenges and comedic announcements instead of recording a live drummer.
