Don Giovanni: Là ci darem la mano

"Là ci darem la mano" from *Don Giovanni* (K. 527) is seduction rendered as music — a duet between the aristocratic libertine Don Giovanni and the peasant girl Zerlina, who understands exactly what is being proposed and cannot quite bring herself to refuse. The melodic line is disarmingly simple: a slow, courtly dance in A major, the two voices beginning in alternation and gradually drawing together until they sing in unison at the song's climax, the musical merging mirroring the social and erotic drama. Mozart's genius here is in giving Zerlina's internal conflict an audible form — her hesitating responses ("Vorrei e non vorrei," "I'd like to and I wouldn't"), her voice wavering between desire and self-preservation before capitulating entirely to the melody's pull. Don Giovanni's vocal line is smooth to the point of seeming effortless, which is the point: this is a man for whom seduction requires no more effort than breathing. The orchestration remains chamber-like throughout, intimate rather than theatrical, keeping the listener uncomfortably close to a private negotiation. It is one of the most psychologically acute pieces of musical dramaturgy ever written, disguised as a simple love song.
