Dreamy harp sounds have long been used in film, games and online video to signal fantasy, sleep, memory and gentle emotion, and short clips like this one circulate widely on soundboards for creators who need a quick atmospheric touch. Because the instrument is instantly recognisable and carries no lyrics, it can sit over almost any visual without clashing with dialogue. Its continued popularity comes from that versatility: one brief passage can suggest wonder, tenderness or a shift into another world in seconds.
