Now this is something really unique … Violins with 5 playayble strings combining violin and viola (“quinton”) and with additional “sympathetic” strings (7 - 25). This brings a totally new dimension to the violin sound - 3D spherical sound that is very touching and inspiring. These instruments were played by Ivo Sedlacek at his numberless performances and recordings. It is a result of 15 years development.The only instruments of their kind in the world. Now some of these instruments are available to anyone who wants to open a new space in his violin playing and music creation.
