"Shape of my heart" is a song by English artist Sting from his album Ten Summoner's Tales, released in 1993. The song was co written by guitarist Dominic Miller. Sting explained that through "Shape of My Heart", he wanted to tell the story of a "card player, a gambler who gambles not to win but to try and figure out something; to figure out some kind of mystical logic in luck, or chance; some kind of scientific, almost religious law." This title was used for the end credits of the film Léon with Jean Reno and Natalie Portman.
