The violin heard in this video was strung with violin strings made from spider silk. Does it sound different to you? Me neither, but I'm no violin connoisseur. From New Scientist:
(Nara Medical University professor Shigeyoshi) Osaki learned how to coax Nephila maculate spiders to spin out long strands of dragline, the strongest form of silk. He bundled filaments together and twisted them, then twisted three of these bundles together to make each string. The thickest of these, the G string, holds 15,000 filaments…
Osaki tested the new strings by comparing their performance with three established materials: steel, nylon and gut. He says that the spider silk has a unique and "brilliant" timbre, or quality of tone.
