7. Octobass
So far all the musical instruments that made this list of unusual musical instruments with weird names were rather modern creations. But the Octobass was designed and produced way back in 1850 by Jean-Baptiste Vuillaume a talented French violin maker. His intention was to come up with an instrument that would add a low-end rumble to any large orchestra. However, what sets this particular instrument apart is its sheer size and bulk. The player has to stand on a platform to be able to play the thing. The Octobass is huge, and probably the largest string musical instrument.
