Isolde, promised to King Marke in marriage, and her handmaid, Brangäne, are quartered aboard Tristan's ship being transported to the king's lands in Cornwall. The opera opens with the voice of a young sailor singing of a "wild Irish maid", ("Westwärts schweift der Blick") which Isolde construes to be a mocking reference to herself. In a furious outburst, she wishes the seas to rise up and sink the ship, killing herself and all on board ("Erwache mir wieder, kühne Gewalt"). Her scorn and rage are directed particularly at Tristan, the knight responsible for taking her to Marke, and Isolde sends Brangäne to command Tristan to appear before her ("Befehlen liess' dem Eigenholde"). Tristan, however, refuses Brangäne's request, claiming that his place is at the helm. His henchman, Kurwenal, answers more brusquely, saying that Isolde is in no position to command Tristan and reminds Brangäne that Isolde's previous fiancé, Morold, was killed by Tristan ("Herr Morold zog zu Meere her").
