The hallelujah choir sting has been a comedy shorthand for heaven, relief and revelation for decades in cartoons, ads and sketches, and this ultra-short ohh version condenses that idea into a single beat.

Its popularity comes from how recognisable the rising voices are, even at half a second long, making it ideal for memes, edits and reaction clips where timing matters more than length.
