This chapter approaches Wagner’s Tristan und Isolde from the viewpoint of its temporal dramaturgy. It highlights the opera’s specificity by interpreting it as a tragedy of hearing: a tragedy in which the main characters, Tristan and Isolde, stuck in their melancholy, are bound to the discursive and plot-oriented forms of musical-operatic time, while the redemption they desire – aesthetically presented by Wagner through acoustic means – points musically beyond the opera’s temporal structures. These connections can be traced on the structural level and that of musical dramaturgy and musical form but also on the level of the characters’ psychology.
