The level-up sound comes from The Elder Scrolls V: Skyrim, the open-world role-playing game released by Bethesda Game Studios in 2011. In the game it plays when the Dragonborn gains enough experience to level up, signalling time to choose a new health, magicka or stamina increase and a perk. As Skyrim remained popular through re-releases, mods, streams and gameplay videos, the cue became widely recognised beyond its original players. Creators now reuse it as shorthand for progress, even in videos that have nothing to do with Skyrim itself.
