Our Design and Development Process
A key element of our creative process is working with musicians, one to one, testing string prototypes. For example, Maria Kliegel is a professor at the Cologne Academy of Music and we met up with her at the Bürgermeisterhaus in Essen, Germany to talk strings. The responses and insights gained from artists directly influences the formulation of new designs with the final creative phase being part of the audience at live performance.

“Our mission is to produce strings that allow musicians to express nuances in musical expression that close the distance between the composer and audience.”
