O mio babbino caro ("Oh my ear papa") is an aria from the opera Gianni Schicchi (1918) by Giacomo Puccini. It is sung by Lauretta after tensions between Schicchi and his prospective in-laws have reached a breaking point that threatens to separate her from Rinuccio, the boy she loves. It provides a contrasting interlude expressing lyrical simplicity and single-hearted love in the atmosphere of hypocrisy, jealousy, double-dealing and feuding in medieval Florence of Puccini's only comedy, and it provides the only set-piece in the through-composed conversational musical give-and-take.
