The 13 weirdest musical instruments ever
Constructed in 1850 by certifiable genius and fan of massive string instruments Jean-Baptiste Vuillaume, the Octobass is a chuffing massive double bass that stands at 3.48m tall. Which is ridiculous, really, seeing as it's too big to play with the hands - there are elaborate foot-pedals to make it possible. Apparently Berlioz was a fan, and wrote about it in his treatise on orchestration.
