Jung Jae-il: The Composer Behind Squid Game’s Haunting Sounds

Korean composer Jung Jae-il, the musical architect behind Netflix’s global phenomenon *Squid Game*, is currently embarking on a world tour, celebrating the meticulously crafted imperfections embedded within his renowned scores. For many of the hundreds of millions who tuned into *Squid Game*, the series left an indelible mark, both psychologically and audibly. Who could forget the disquieting whistle of a child’s recorder, transforming a seemingly innocent primary school melody into an chilling omen of impending bloodshed? This ingenious subversion is a hallmark of Jung Jae-il’s work, whose career is distinguished by his remarkable ability to infuse familiar sounds with an unsettling and often terrifying new context. He is a master at twisting the naive, the refined, and the elegant into potent, spine-tingling precursors of dread.
