It was first unveiled February 13, 1998. The Virtuoso uses an electromagnet instead of fingering the strings. The electromagnet's position changes the behavior of the vibrating string to attain the desired pitch. The Virtuoso is designed to play a real violin, although its setup requires the strings to be restrung and the
