The power up sound originates from Super Mario Bros, released by Nintendo in 1985 for the NES with music and effects by Koji Kondo. The rising chime was designed to accompany Mario growing after collecting a Super Mushroom, contrasting with the shrinking sound when he takes damage. As Mario became a global gaming icon, the effect was reused across later Mario games and remixes, and it spread online through soundboards, memes and video edits where it now universally signals gaining power or improving.
