This meme sound is based on a rough recorder-style performance of the melody from "My Heart Will Go On," the theme associated with Titanic. The original song became globally famous after the 1997 film, and the intentionally poor cover spread online as a reaction sound for anticlimactic sadness and awkward drama. It remains popular because people instantly recognize the tune, then laugh at how badly it is played. In meme edits, it often fills the same role as Hello darkness my old friend when a moment collapses into failure.
