Viola organista The viola organista is a musical instrument designed by Leonardo da Vinci. It uses a friction belt to vibrate individual strings (similar to how a violin produces sounds), with the strings selected by pressing keys on a keyboard (similar to an organ). Leonardo's design has intrigued instrument makers for more than 400 years. But though similar instruments have been built, no extant instrument constructed directly from Leonardo's incomplete designs is known.
Peter Breisiger Peter Breisiger (also "Briesger", "Bryssiger", fl. 1516-1542, dates of birth and death unknown) was a German organ builder. He was active in the first half of the 16th century, worked in Germany and the Low Countries. Breisiger continued the progressive German tradition of the previous century (represented by Stephan Kaschendorf, Heinrich Traxdorf and others), which dealt away with the old Blockwerk organ by introducing separate divisions. He went further than that and invented several types of stops (including some compound ones). He also authored a number of writings on registration, which are considered today the most important such instructions of the 16th century and are still consulted.
