The harpsichord-viola is a hybrid musical instrument based on the designs of Leonardo da Vinci on folio 93r of the Codex Atlanticus. It is a different project from the viola organista. It is about the size of a child's toy piano. It weighs 33 pounds and straps to the musician's chest. It is unlike anything else in the orchestra. It has the strings of a viola but is played with a keyboard, and it is powered by the musician's legs as he walks. It is built with the materials that Leonardo would have had on hand, including wooden pegs and gears run by twine. In the folio of Leonardo, one can see that the instrument has a harness.
