Wagner’s Tristan und Isolde is one of the most revolutionary works in the history of Western music. It not only transformed the language of opera, but also made “desire” itself a direct and profound subject of music. In September 2026, Taipei Symphony Orchestra (TSO), led by Chief Conductor Alexander Liebreich and joined by German director Christian Räth, will present this monumental late work by Wagner at the Grand Theatre of the Taipei Performing Arts Center, inviting audiences on a profound journey through love, desire, life, and death.“This Tristan Will Be a Terrible Thing!” — Wagner Himself on the Weight of the WorkTristan und Isolde has long been regarded as an opera that can “devour singers.” Its extraordinary length, immense vocal demands, and almost continuously unfolding musical lines test not only the singers’ voices, but also their physical stamina, willpower, and emotional commitment. Wagner himself knew better than anyone just how “terrible” the work could be.Upon completing Act II, Wagner described it as the “artistic culmination” of his career up to that point. Yet as he gradually completed Act III, he exclaimed: “My child! This Tristan will be a terrible thing!”A composer of remarkable versatility, Wagner wrote both the libretto and the music for Tristan und Isolde. He transformed his own painful and impossible love for Mathilde Wesendonck—a married woman with whom he could not openly pursue a relationship—into artistic creation, ultimately giving birth to Tristan und Isolde.A Work That Changed the History of Opera, Making “Desire” AudibleTristan und Isolde was premiered on June 10, 1865, at the Munich National Theatre, conducted by Hans von Bülow. The theatre, located in Munich, was also the birthplace of TSO Chief Conductor Alexander Liebreich, giving him a particularly profound connection to the work.Among the opera’s most famous musical innovations is what later came to be known as the “Tristan Chord.” Through harmonies that continually delay resolution and never quite seem to arrive at a final resting point, Wagner inscribed the very experience of “desire” into the music itself. The melody seems forever to move forward in search of an answer, yet never truly reaches its destination.This musical language of perpetual anticipation not only transformed 19th-century opera, but also profoundly influenced generations of composers who followed. From harmony and melody to dramatic structure, Tristan und Isolde became a crucial turning point in the development of Western music toward modernity.For Liebreich, what makes Tristan und Isolde truly moving is not whether the music provides an answer, but how it keeps us searching for one.Christian Räth: The Stage Is Not a Recreation of the Story, but a Journey into the Characters’ Inner WorldsDirector Christian Räth approaches Tristan und Isolde through the inner worlds of its characters, viewing the opera as a drama that unfolds deep within the human psyche.In Räth’s theatrical language, “day” and “night” are more than changes in time. They symbolize the tension between social conventions and inner desire. Day represents responsibility, order, and the external world; night allows the characters to temporarily shed their identities and constraints and return to their most authentic selves.The stage therefore does not seek to recreate a realistic historical setting. Instead, it becomes a visualization of the characters’ psychological and subconscious worlds. Brangäne and Isolde, as well as Kurwenal and Tristan, mirror one another, as though reflecting different facets of the same soul.A World-Class Wagnerian Cast Brings a Tidal Wave of Sound and EmotionBringing this profound journey of the soul to the stage demands exceptional performers. For this production, TSO has assembled two distinguished singers whose careers have placed them among the leading Wagnerian artists of their generation.Swedish tenor Michael Weinius, who sings the role of Tristan, won First Prize at the International Wagner Competition in 2008. He has performed at leading opera houses including Deutsche Oper Berlin, the Paris Opera, Zurich Opera, and the Vienna State Opera. In recent years, his interpretation of Tristan has further established him as one of today’s important Wagnerian tenors.Joining him is Armenian soprano Lianna Haroutounian, who has appeared on the stages of major opera houses around the world, including the Royal Opera House, the Metropolitan Opera, the Vienna State Opera, the Paris Opera, and the Teatro Real in Madrid. Last season, she made a celebrated debut as Isolde at the Opéra Royal de Liège. During the 2025/26 season, she reprised the role in the opening production at Teatro Cervantes in Málaga, captivating audiences once again.From the “Tristan Chord” to the Liebestod: A Journey Through Love and LifeFrom the opening “Tristan Chord” to Isolde’s final Liebestod, Tristan und Isolde traces a profound emotional journey: one embodies an unspoken and seemingly unattainable desire, while the other carries love toward a state beyond life and death.In September 2026, TSO invites audiences to experience the profound emotional tides of Wagner’s music and to follow the deepest desires within ourselves.
