Place it immediately after the failed moment, then follow it with the Roblox Oof Sound to underline the mistake before moving on, or open with the Careless Whisper Sax Riff for a slow build and let this clip close the scene.
About this sound
This is a just-under-ten-second excerpt of Simon & Garfunkel's folk-rock song, with a hushed vocal over thin guitar and a slow, restrained arrangement. It feels quietly sad and empty, like the air leaving a room after something has gone wrong. The clip comes from The Sound of Silence, released by the duo in the 1960s.
