During the evening, Othello goes out for a walk with Lodovico. Desemona and Emilia have a debate about marital fidelity. Desdemona argues that faithfulness is necessary and good, but Emilia argues for the rights of sexual freedom as men have. Desdemona vaguely prophesizes her death when she sings a song about unfortunate love.
