Octobass
The octobass is an extremely large bowed string instrument constructed about 1850 in Paris by the French luthier Jean Baptiste Vuillaume (1798-1875). It has three strings and is essentially a larger version of the double bass (the specimen in the collection of the Musée de la Musique in Paris measures 3.48 meters in length, whereas a full size double bass is generally approximately 2 meters in length). Because of the impractically large size of its fingerboard and thickness of its strings, the strings were stopped by the use of an intricate system of hand- and foot-activated levers and pedals. The instrument was, in fact, so large that it took two musicians to play: one to bow and the other to control the “fingering,” and was consequently never produced on a large scale or used much by composers.
