[7] His clients include Leila Josefowicz, Yo-Yo Ma, David Finckel, Cho-Liang Lin, Maxim Vengerov, Joshua Bell, Dylana Jenson, Matthew Lipman and the Emerson String Quartet.
The Violinmaker, a book written by John Marchese, chronicles the making of a violin for Emerson String Quartet violinist Eugene Drucker.
[9] Since 2006, Zygmuntowicz has been the creative director of the Strad3D project, which The Strad Library called "One of the most groundbreaking and comprehensive studies of the violin form ever conceived."
Zygmuntowicz turned the endeavor into a broad collaborative project, bringing together makers, musicians, filmmakers, acoustical engineers, and other researchers - among them physicist and co-developer George Bissinger, who had pioneered the use of vibration scanning using lasers.
[10] According to Zygmuntowicz, "The instruments were gently activated by tapping the bridge, and then three scanning lasers detected the resulting patterns of vibration, which were revealed on screen as a rippling landscape of colour and motion, rather like a motion-capture animated film."
[10] Zygmuntowicz is an active speaker at museums, conferences, chamber music festivals, and intensive workshops, on topics ranging from historical and contemporary violin-making techniques to modern violin acoustics and cutting-edge research.
