Overview

Viola organista (Codex Atlanticus, 1488–1489) - Viola organista
Viola organista (Codex Atlanticus, 1488–1489)

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.

Description

Leonardo designed many different and elaborate models of viola organista, as preserved in his notebooks of 1488–1489 and in the drawings in the Codex Atlanticus and Manuscript H.[1]

In the first model the friction of the strings was achieved by a mechanical bow traveling sideways. The second model featured a single rotating wheel, similar to that of the earlier hurdy-gurdy, to play strings. It differs in that a hurdy-gurdy has a small number of strings that are constantly in contact with the wheel, rather than a larger number of strings that can be lowered onto the wheel. A hurdy-gurdy has a keybox with tangents that change the pitches of the strings, rather like placing fingers on violin strings. Leonardo's innovation of a keyboard with a lowering mechanism allowed individual notes to be played, alone or in specific desired chords over a large range of pitches.

Both the mechanical bow and the rotating wheel concepts were abandoned in favor of a third and final model. The main idea of this design was to use one or more wheels, continuously rotating, each of which pulled a looping bow, rather like a fanbelt in an automobile engine, and perpendicular to the instrument's strings. The strings would be pushed downward into the bow by the action of the keys, causing the moving bow to sound the pitch of the string. In one design, the strings were fretted with tangents, so that there were more keys than strings (multiple notes, for example C and C#, would be played on one string). In another design, each note had its own string.

Leonardo's design shows a boxy, vaguely harpsichord-shaped instrument with a hand-cranked bow-wheel, and indeterminate number of strings or keys.

The first known instrument actually constructed using Leonardo's concept, is Hans Heyden's Geigenwerk of 1575. While the concept is the same, the design is very different; modern versions of the instrument have been more or less based on Heyden's design. An etching of the Geigenwerk from 1620 shows an instrument of about the stature and shape of a harpsichord (ie., an piano-shape with flat sides and hard angles). The fully chromatic keyboard appears to have 44 keys, extending about three-and-a-half octaves from low E to a high B. (see illustration) This keyboard range is consistent with harpsichords of the day, although harpsichord keyboards more typically started on low C or low F. The number of strings can't be directly determined, but the design implies one string per key, or 44 strings.[2]

In the etching there appear to be five bow-wheels in the instrument, and a foot-pedal, presumably for turning the wheels. A scale given below the drawing has numbers from one to six; if it assumed these refer to feet, then the instrument is a bit over 6 feet long, which again is a scale in keeping with harpsichords of the day. The actual tuning of the instrument is not specified, but given the number of keys and the size of the instrument, it probably extended from around E2 to B5. Variations on this design have been produced over the past four centuries, with varying range, number of keys, and number of bow-wheels.[3]

History

It is not known if Leonardo ever built a working prototype of this instrument. As noted above, the first similar instrument actually to be constructed was the Geigenwerk of 1575 by Hans Heyden, a German instrument inventor. However, Geigenwerk is not based on Leonardo's designs. It uses several friction wheels instead of a friction belt to vibrate the strings, and requires two people to play it: one to turn the crank to put the rosined wheels in motion, and the other to work the keys.[4]

Georg Gandi, an organist in Ilmenau, constructed a similar instrument with some improvements in 1709 and called it the piano viol. In 1741, two inventors—Le voir in Paris and Hohlfeld in Berlin—independently constructed versions of a bowed piano, similar to Heydens design. In 1754 a horsehair covering was added to the wheels of the bowed piano, which was termed the viola da gamba piano. Other instrument makers continued to improve the design through the remainder of the 18th, and into the early 19th centuries, though it never became widespread or common.[5]

These instruments remained primarily museum curiosities until a few modern instrument builders began to take an interest in creating reconstructions of the Geigenwerk, but calling them viola organista. Akio Obuchi built several instruments as early as 1993.[6] In 2004, one of them was used in a concert in Genoa, Italy. In 2013, Sławomir Zubrzycki finished construction and performed on his instrument[7] at the Academy of Music in Kraków. Zubrzycki's instrument contains four bow-wheels (spun by a foot-pedal operated by the player), 49 keys, and a range extending from F1 to F5.

A modern instrument similar in concept, if not design, is the wheel harp, created by Jon Jones and Mitchell Manger in 2013, and debuted at the NAMM Show that year, in Anaheim, California.[8]

The musician Björk uses this instrument on the acoustic version of her album Vulnicura (Vulnicura Strings (Vulnicura: The Acoustic Version – Strings, Voice and Viola Organista Only)), in the song Black Lake.
