Trivia: What strange instrument did Leonardo invent?
Correct Answer: Viola organista
So why is this answer correct? : The viola organista is best described as a cross between a harpsichord and a cello. Like most of Leonardo da Vinci’s designs, the instrument was never made by Leonardo himself. Centuries after the artist’s death, a Polish pianist named Slawomir Zubrzycki brought the design to life and debuted the creation at a concert in Krakow, Poland, in 2013.
