Place it in the middle of a build-up sequence, just before the key visual change, then follow it with a Vine Boom Sound Effect for impact and a Bell Ding Sound Effect to mark the reveal.
About this sound
A six-second tension effect that begins low and quiet, then climbs in volume and intensity as a rising tone tightens around the listener. At the peak it releases suddenly, dropping away to leave an empty, relieved pause. The build makes ordinary moments feel suspenseful and cinematic, while the abrupt fall can turn the same moment awkward or funny.
