The line originates from Sigma, a playable Overwatch hero introduced in 2019. Sigma is a Dutch astrophysicist whose story and abilities revolve around gravity, while his dialogue frequently references a mysterious melody. “What is that melody?” is associated with his Gravitic Flux ultimate and became one of his most recognizable quotes. Players carried it beyond matches through gameplay clips, character edits, reaction videos, and memes. Its lasting appeal comes from Sigma’s unusual combination of calm curiosity, immense power, and ominous delivery.
About this sound
Sigma's “What is that melody?” voice line comes from Overwatch and accompanies Gravitic Flux, often used in gaming edits for dramatic or puzzled moments.
This short clip captures Sigma’s calm, curious delivery of “What is that melody?” during Gravitic Flux in Overwatch. His measured voice turns the ultimate ability into something eerie and theatrical, contrasting with the chaos of the match. The line sounds as though Sigma is distracted by music only he can perceive, which gives it an unsettling edge. In videos, that mix of wonder and menace works well for sudden realizations, strange discoveries, or moments when someone becomes unexpectedly powerful on screen.
