Rhythm Doctor is an indie rhythm game by 7th Beat Games in which players press a key on the seventh beat to treat patients, and its clean menu sounds have become familiar to fans who record and share gameplay clips. This very short tab sound comes from that interface, where small blips confirm selections without breaking the musical flow. Because it is so brief and recognisable to players, creators reuse it outside the game as a neat UI tap for edits, tutorials and short videos.
