Juggling balls. Sensors. Live music. Light.
Amble is itself a fusion — Audio, Music, Ball. Fusion comes from sensor fusion, the technique at the heart of how the balls understand their own motion.
Duo · Premiered May 2026
The full-format show: Noah Schiltknecht and Benjamin Beaujard, 50 minutes, five hands of sound-making balls. Echoes explores memory and childhood through juggling that composes its own music — patterns that call, answer, and return changed, like echoes.
Duration: 50 min · Full format · All audiences

The small-format solo: 20 minutes, one juggler, one instrument made of flying balls. Named for Marin Mersenne (1588–1648), the friar-mathematician called the father of acoustics — the first to write down the laws of the vibrating string, turning number into harmony. Exactly what the balls do.
Duration: 20 min · Small format · All audiences — a dedicated run for ages 6–13 has been performed.
Inquire about booking →Amble Fusion redefines juggling as an immersive experience for eye, ear, and heart. Traditional visual art merges with music and light, becoming a truly emotional language.
Each Amble Fusion ball is built from scratch: custom electronics, motion sensors that read every throw, catch, spin, and moment of stillness, and a wireless link that streams that data off the ball in real time. The movement becomes sound — synthesized live — and light, both inside the balls and across the stage.
The balls don't play back recordings. They are instruments. The music only exists while the juggling does.
It started in 2017 at DOCH, the Stockholm circus school, inside Stefan Sing's workshop. A group of jugglers were playing together as a juggling orchestra — collective rhythm-making with balls. Bruno Spoerri, the Swiss composer and inventor, built an early video-tracking system that turned ball positions into sound. The question formed: what if the balls themselves could hear their own motion? In Beijing that same year, the seed of the project took root.
Tim Bouwens built the first three hardware prototypes — rough, fragile, but alive. Each ball carried a sensor and a wireless link. To make sense of the data they produced, Noah began teaching himself code and Max/MSP from scratch, late nights and weekends, with no engineering background. Bruno Spoerri mentored the early sound systems and software, patiently answering questions from someone learning an entire field on the fly.
There was a darkest moment. The prototypes were unreliable, the music was crude, the gap between the idea and the reality felt unbridgeable. Progress was slow and invisible. But the project refused to die — because every so often, for a few seconds, a pattern would land and the sound would be exactly right, and that was enough to keep going.
Hannah Marti designed the casings that made the balls rugged enough to perform with. Denis Paumier and Sylvain Garnavault donated a fleet of sensor-balls, giving the project real mass. A community crowdfunding campaign in 2021 funded the first full performance set. In autumn 2024, Fabian Laute joined and built the sound engine — the system that finally translated raw motion data into a living musical instrument. In December 2024, Benjamin Beaujard joined as juggling collaborator and pattern composer, and the work became a dialogue between two jugglers instead of a single voice.
And then it was on stage. Residencies at Maison des Jonglages in Paris, Dynamo in Odense, La Grille, and Br'Ain du Cirque and Maison du Cirque in Bourg-en-Bresse shaped the piece season after season. A presentation at the Aula der Kantonsschule Glarus in November 2025. In May 2026, Amble Fusion: Echoes premiered — the full-format duo show. In July 2026, Amble Fusion: Mersenne followed — the solo. The instrument had become a repertoire.
"I consider Noah's project Amble Fusion to be unique and relevant — at the intersection between art and scientific research, with the goal of being at the forefront of the development of circus."
— Viktoria Dalborg, Artistic Director, Kompani Giraff
