Nino Rota's music was a key element in the Godfather films, capturing the essence of the Corleones: stately, old-world Italian on the surface, with hints of danger lurking beneath. Much of the soundtrack revolves around two themes: The slightly ominous "The Godfather Waltz" and the more elegant "Love Theme from ‘The Godfather’", which returns on mandolin during the finale. Lighter moments include the pomp-and-ceremony of "Connie's Wedding" and the one vocal, "I Have But One Heart", featuring crooner Al Martino, who played the film's Sinatra-inspired character.
