Leonardo Da Vinci dabbled in much more than art. He conceived of several machines. One such concept was a new musical instrument that can be thought of as a cross between a harpsichord and a cello.
NPR has done a nice report on Polish pianist Slawomir Zibrzycki who has managed to bring the instrument to live after a four year endeavor.
The link to the article has both the full report and a YouTube video (embedded below) where you can listen to the concert unveiling the Viola Organista.
