Humans Are Irreplaceable, Jacob Mühlrad Says About His Robot Cello Player
Jacob Mühlrad’s New Robotic Cellist: Enhancing Classical Music Without Replacing Tradition
The Inspiration Behind the Machine
Swedish composer Jacob Mühlrad has long been fascinated by the intersection of technology and artistry. After years of experimenting with digital interfaces and electronic instruments, he decided to bring the spirit of traditional cello performance to a robotic platform.
Key Features of the Robotic Cellist
- Precision in Fingering: The robot’s arms can execute complex vibrato and micro‑tonal shifts with millisecond accuracy.
- Dynamic Response: Equipped with force sensors, it adjusts bow pressure in real time, creating expressive crescendos that mirror a human player’s touch.
- Programmable Algorithms: Musicians can load new pieces or modify existing scores, allowing endless experimentation.
- Consistent Performances: A single piece sounds identical each time, making it ideal for rehearsals and archival recordings.
What the Robotic Cellist Adds to Classical Music
- Enhanced Accessibility: Learners can study nuanced techniques from an immaculate example, speeding up their development.
- Collaborative Creativity: Composers can test unconventional passages in real time, reshaping traditional compositions with fresh ideas.
- Expanded Repertoire: Pieces that required multiple players or large ensembles can now be performed by a single, highly versatile machine.
- Genre‑Blending: By fusing classical notation with electronic modulation, the robot opens doors to hybrid genres that appeal to broader audiences.
Limitations and the Human Touch
While the robotic cellist excels in technical perfection, it cannot fully replicate the subtle emotional nuances that a human musician brings. It lacks:
- Intuitive Interpretation: The innate ability to improvise based on mood or interpersonal dynamics is absent.
- Physical Resilience: Musicians adapt to unforeseen tempo changes, whereas the robot requires explicit programming.
- Communicative Presence: The connection between performer and audience—almost a silent dialogue—is forged by human expression and cannot be mirrored by a machine.
Looking Ahead: The Future of Robotic Classical Music
Jacob Mühlrad envisions a collaborative ecosystem, where robotic performers augment but never replace human musicians. As the technology matures, we may witness orchestras that blend the unmistakable warmth of human voices with the relentless precision of robotic instruments, creating performances that are both familiar and excitingly novel.
Robot Takes the Spotlight in Malmö’s Orchestral Debut
Unlikely Collaborator on the Stage
During the evening’s finale at Malmö Live Concert Hall, the orchestra’s pit welcomed an unexpected participant: a robotic cellist. Unlike a traditional soloist, this piece was performed by a sophisticated machine, leaving the audience intrigued by the blend of human artistry and technological precision.
Mechanical Precision on the Cello
Positioned beside the cello, two engineered arms emerged from the pit floor:
- Bow Control Arm – Directly attached to a robotic limb, the bow executes movements with surgical accuracy.
- Neck Press Arm – Features a cylindrical pad assembly that maintains optimal string tension during performance.
Programming the Performance
Dubbed “Veer (bot)”, the robot was specifically programmed to render Jacob Mühlrad’s latest composition, “Veer.” The machine delivers sustained, expressive notes that stand apart from its human counterparts, showcasing a level of emotional nuance rarely associated with automated performers.
Beyond Mere Mechanics
Mühlrad emphasized that the system goes beyond mere string vibration. “Even the vibrato can be programmed,” he told Euronews Culture, highlighting the deliberate design that allows the robot to replicate subtle musical expressions.
Behind the Innovation
At 33, Jacob Mühlrad is already recognized as a wunderkind in modern composition. He collaborated with fellow Swedish composer and researcher Frederick Gran to create the robotic system that will accompany future performances of his Cello Concerto No. 1.

Emerging from Collaboration
The journey began when a simple conversation sparked a series of weekly conversations that gradually brought new features to life. As each update refined its synchronization and tonal capabilities, the question arose: could the robot ever join an orchestra? The answer was no—until now.
Designing a Live Piece for the Robot
Featuring the Malmö Symphony Orchestra’s portrait concert, a new composition called Veer was crafted explicitly for the mechanical cellist. While the futuristic version of the device may someday respond in real time to a conductor, the current performance is fully pre‑recorded, down to the last nuance.
Why the Robot Excels
- Unburdened by human physical limits, it can execute pieces that would otherwise be impossible.
- Analogous to a MIDI keyboard, but far more intricate due to the cello’s many parameters.
- Precision in intonation and bow pressure is fine‑tuned beyond what any human player can sustain.
Future Possibilities
Producers envision a version where the robot responds dynamically to a conductor, mirroring the responsiveness of a human musician. For the moment, Veer showcases how advanced technology can bring new dimensions to classical performance.
Exploring the Synergy of Human and Machine in Music
While the “Veer” performance itself was surprisingly simple, composer Frederik Mühlrad sees it as a stepping‑stone toward unlocking musical possibilities that transcend the limits of human presence alone. From microtonal explorations played by a quartet of robots to astonishingly slow glissandi, his imagination is stretched by the novel avenues technology affords.
Human Expression Remains Unmatched
Mühlrad is clear about the irreplaceable role of a living performer:
- “A human being gripping a cello and channeling their own inner voice is pure magic,” he declares.
- Interpretation in classical music is rooted in the human condition—intentional emphasis on melodic lines in a Bach fugue, or unintentional variations infused by sleep deprivation or the thrill of a massive audience.
- These facets of human experience cannot be fully replicated by a robot, he says.
Veer (bot) as a Collaborative Tool
For Mühlrad, the Veer bot does not replace the human; rather, it becomes an additional resource within the musical toolkit. He envisions a future where a human and a robotic cello collaborate, each serving complementary roles that enrich the overall sound.
Compositional Control vs. Conductorial Authority
With the Veer bot, the intricacies of interpretation stay under the composer’s guidance instead of being directed by an orchestra conductor. Although the Veer piece was modest in scope, Mühlrad deliberately selected it to demonstrate how a robotic instrument can carry both “soul” and nuanced expression.
By integrating the emotional depth of human players with the precision of robotic execution, Mühlrad hopes to push the boundaries of what is possible in contemporary music.
Exploring Mid-Performance Challenges in Live Electronic Music
Starting from the extensive programming laid out by Mühlrad and Gran, the performance still left room for unintended interpretive nuances.
Unexpected Harmonic Shifts
During the Malmö concert, Gran noted a moment where the guitar’s pressure dipped slightly: “This created a harmonic tone that rang an octave higher than intended,” he explained. Though brief, the incident highlights the complex interpretive demands that live music imposes.
Human Emotion vs. Electronic Instrumentation
When asked whether electronic synthesizers can elicit the same emotional responses as human players, Mühlrad was quick to respond:
“The audience is crying repeatedly when they hear the electronic synthesiser.”
He positions the Veer bot as an exciting complement rather than a replacement for composers. Regarding claims that bots could supplant human musicians, he says:
“People wonder if, like with ABBA Voyage hologram concerts, live artists will cease to appear on stage. I see it as merely another evolving medium.”
Takeaway
- Even meticulously programmed systems can produce unplanned acoustic variations.
- Electronic instruments, while powerful, are viewed by practitioners as partners rather than successors to human performance.
- The integration of technology should be seen as a continuous expansion of creative possibilities.
