Tapetatapetatapeta... This is a form of background music designed to increase anticipation for whatever The Reveal is. (BOOM!) Happens both in Real Life and in audiovisual media. Less common than it used to be: Some rock stars abused drum roll privileges with their ten-minute drum solos, and not every drum machine can pull off a drum roll. Instead, producers use the visual equivalent, cutting every two seconds (or is that two frames?). But true drum rolls still get used, especially by shows wanting to evoke nostalgia, and have the advantage of not causing epileptic seizures.
