This sound is known online as a Deltarune fanfare, taken from the audio style of Toby Fox's 2018 game Deltarune. Short celebratory stings from the game are commonly clipped and reused in meme edits, Twitch highlights and gaming compilations because they instantly signal success or discovery. Its continued use comes from how recognizable Deltarune is among RPG fans and how neatly a quick fanfare fits score screens, reveals and comedic achievements in short-form videos.
