The Klangrad consists of a rotating, circular soundbox equipped with several overlapping playing surfaces: The Klangrad combines the musical and playful potentials of the monochord, the tambura, and the kantele in a single soundbox.

Its unique characteristics and possibilities are best realized when used as a group instrument: the KlangRad® offers people of all ages the opportunity to connect with one another through playing an instrument together.
The instrument can also be played by a single person.
KlangRad® is registered with the German Patent and Trademark Office as a word mark and as a utility model.

The stringed instrument was developed for the international competition organized by the “German Music Therapy Association” and the “Frankfurt Music Fair” in 2019, where it was awarded first prize.

In 2025, the Berlin Chamber of Crafts honored the Klangrad Ensemble as part of the Draft and Design 2024—Berlin State Prize for Arts and Crafts—and showcased it to the public for two months in the exhibition “The Art of Making” at the Berlin Museum of Decorative Arts.
