Learning to play a musical instrument is one of the most commonly abandoned pursuits in modern life. The gap between wanting to play and being able to usually involves years of lessons, expensive gear, and a dedicated practice space. That’s a lot of friction for something that’s supposed to be joyful, and it keeps most people as spectators for their entire lives.
The designers at YUPD started from a different observation. Most people are already making music, just not in any formal sense. Tapping out a beat on a desk, drumming with pens, humming a melody while doing chores, these are all musical impulses that rarely have anywhere to land. BREMEN is a modular performance system designed to change that by letting everyday objects become actual instruments.

Two of BREMEN’s four modules handle the percussive and string side of things. The Guitar Module and Drum Module are compact cylinders that slide over any stick-shaped object, whether that’s a pen, a ruler, or an actual broom handle. Once attached, they translate the way you swing or strike into guitar or drum sounds, sent wirelessly to the system’s central speaker.
The Piano Module takes a different approach. Two slim, bar-shaped units placed at opposite ends of a desk detect the distance between them and create an invisible keyboard in the space between. The sensors track finger movement above the surface and trigger the matching notes, so you’re essentially playing piano in thin air. No keys, no bench, no sheet music required.
All three modules feed into BREMEN_HEN, the system’s speaker. It receives the separate performances from the guitar, drum, and piano modules and blends them into a single ensemble output. The speaker itself has a distinctive triangular cross-section with a fabric mesh face, making it compact enough to carry by hand and functional enough to fill a room with actual band-level sound.
That last part matters. The whole point of BREMEN is that the stage can be wherever you happen to be, a classroom, a courtyard, a park. Three people with sticks and a pair of piano bars are suddenly a band. Nobody had to haul gear across town or book a rehearsal room. It’s the kind of spontaneity that music rarely allows for anymore.
YUPD’s concept goes beyond accessibility, though that’s clearly central to it. More fundamentally, it’s a rethinking of what counts as a musical instrument, one that argues the answer could be almost anything. A broom becomes a guitar, a desk becomes a piano, and a group of people with no formal training becomes something resembling a band. That’s a surprisingly generous idea for something that fits in a backpack.
