Georg Friedrich Handel composed Messiah in 1741 and it premiered in Dublin in 1742, with the Hallelujah Chorus closing Part II. Its text repeats 'Hallelujah' and 'King of Kings' in a powerful choral climax that became one of classical music's most quoted passages. Online, the short excerpt spread as 'alerta de aleluia' on soundboards, a ready-made praise alert for memes and edits. It is often paired with kids cheering clips for over-the-top celebration scenes, and remains popular because almost everyone recognises the tune within a second.
