Place this clip early in a horror edit, ahead of the reveal, then follow it with the FNAF Jumpscare Scream for the payoff. Keep it as the background layer while a quieter moment or a haunted character image stays on screen, and bring in a second sound only after the scare lands.
About this sound
This 22-second clip is a slow music-box-style tune linked to the Puppet, also called the Marionette, in Five Nights at Freddy's. Its delicate notes drift in an uneven, haunted pattern that makes a listener feel watched and uneasy, even before anything startling happens. Fans recognise it as creepy Puppet music from the FNAF universe.
