Beyond Sound: How “Hidden Heartache” is Redefining Musical Perception at the Münchener Biennale
Music is traditionally defined by what we hear, but a groundbreaking new production at the 2026 Münchener Biennale is challenging that fundamental assumption. “Hidden Heartache,” a music theater piece that merges movement, vibration, and visual rhythm, is shifting the focus from the auditory to the visceral, creating a shared space where hearing and deaf performers interact on equal footing.
Developed by Swiss pianist Simone Keller, the work moves beyond traditional composition to explore how music can be felt and seen, offering a profound commentary on the diverse ways humans experience resonance.
A Dialogue Between Hearing and Silence
At the heart of “Hidden Heartache” is a deliberate collaboration between two different worlds: the hearing and the deaf. The production features a cast of four performers—two deaf and two hearing—who work together to create a “web of visual rhythms.” This isn’t merely a performance about deafness; it is a complex exploration of perspective.
Irish composer Ailís Ní Ríain, who co-composed the music with Julie Herndon, emphasizes that the work avoids superficial messaging. Instead, it embraces the complexity of the performers’ lived experiences. The title itself, “Hidden Heartache,” touches on a deeply personal reality of the deaf experience.
“To be deaf is very lonely. That is the truth. And that is exactly what is in the title: the loneliness and isolation that many deaf people experience.”
By bringing these different perspectives to the stage, the production asks a radical question: What is music, actually?
Making the Invisible Tangible: Vibration and Movement
For Simone Keller, the project represented a significant evolution in her identity as a musician. Having spent her career as an “ear-person,” Keller sought to bridge the gap between acoustic music and the sensory experiences of those who cannot hear. This led to a production where music is rendered visible and physically felt.
To achieve this, the production utilizes several innovative methods:
- Tactile Technology: The use of “Buttkickers”—specialized vibration systems placed under seats—allows the audience to experience sound through physical resonance, much like the immersive sensation of 4D cinema.
- Visual Choreography: Movement and gesture become primary tools of communication. As composer Julie Herndon notes, writing for deaf performers heightens the importance of how movement can communicate with an audience as powerfully as sound.
- Instrumental Interaction: Performers interact with the piano in non-traditional ways—climbing its body or running sponges across the strings—transforming the instrument into a source of vibration and visual texture rather than just a melodic tool.
The Münchener Biennale 2026 Context
The premiere of “Hidden Heartache” takes place at the HochX Theater in Munich, as part of the Münchener Biennale. This year’s festival, led by Katrin Beck and Manuela Kerer, continues to push the boundaries of contemporary performance, providing a platform for works that challenge the status quo of musical perception.
As the festival highlights the intersection of body and sound, “Hidden Heartache” stands out as a testament to the idea that music is not just an acoustic phenomenon, but a physical and visual one.
Key Takeaways: The Sensory Shift in “Hidden Heartache”
| Feature | Traditional Music Theater | “Hidden Heartache” Approach |
|---|---|---|
| Primary Sense | Auditory (Hearing) | Multisensory (Vibration, Sight, Touch) |
| Core Medium | Acoustic Sound Waves | Physical Resonance & Gesture |
| Performer Dynamic | Hearing-centric | Collaborative dialogue between deaf and hearing artists |
| Audience Experience | Passive listening | Active, physical immersion via vibration systems |
Frequently Asked Questions
What is the main theme of “Hidden Heartache”?
The piece explores the different ways people perceive music, specifically focusing on the intersection of hearing and deaf perspectives, while addressing the themes of isolation and loneliness inherent in the deaf experience.
How can the audience “hear” the music if they are deaf or if the music is non-acoustic?
The production uses “Buttkickers” (vibration systems) to turn sound into physical sensations that can be felt through the body, alongside highly visual choreography and movement.
Who are the primary creators of the piece?
The project was developed by Swiss pianist Simone Keller, with musical compositions by Ailís Ní Ríain and Julie Herndon.
