Japan scientist makes violin strings from spider silk

Mar 06, 2012
Nara Medical University professor Shigeyoshi Osaki, seen here playing a violin which has strings made of spider silk, at his laboratory in Kashihara city in Nara prefecture, western Japan.

A Japanese scientist said he has made violin strings out of spider silk and claims that -- in the right hands -- they produce a beautiful sound.

Thousands of the tiny strands can be wound together to produce a strong but flexible string that is perfect for the instrument, said Shigeyoshi Osaki, professor of polymer chemistry at Nara Medical University.

Osaki, who has been working with for 35 years, has previously suggested the material could be used for surgical sutures or for bullet proof vests, but his passion for the violin inspired him to create something with a musical twist.

In the process of weaving the threads, their shape changes from cylindrical to polygonal, which means they fit together much better, Osaki told AFP.

"During the assembly of normal threads there are many spaces between individual fibres," he said.

"What we achieved left no space among the . It made the strings stronger. This can have all sorts of applications in our day-to-day lives," he said, adding 300 female Nephila maculata spiders had provided his raw materials.

The strength and durability of spider silk is not a , with previous studies showing it can withstand and the effects of ultraviolet light.

Osaki once produced a rope spun from spider silk that he said could theoretically support a 600 kilogram (1,300 pound) weight.

Now his latest creation is making waves among musicians, who have praised the sonorous quality of the spider silk violin strings for their "soft and profound timbre".

"Professional violinists have said they can tell the difference" whether the strings are on a or on Osaki's own $1,200 violin, he said.

"It's one thing to create scientifically meaningful items, but I also wanted to produce something that would be socially accepted by ordinary people," he said.

Details of Osaki's research will be published in , a journal of the American Physical Society.

Beauty, through SCIENCE!

It is a great pity there is no attached sound-bite. I'd love to hear them.

I'd like a pair for an electric guitar then. That damn high E string can't handle my abuse.

I wonder if they will detune over time.

Spider silk is more susceptible to contraction due to water. Up to 50% in fact. I imagine, the player would have to wear latex gloves and play in a generally dry environment to ensure the strings don't instantly go out of tune.

Xbw: Don't electric guitar strings have to be conductive? I believe spider silk is an insulator.

Good point, although it is possible to still use them acoustically with an electric pickup.

"Professional violinists have said they can tell the difference" whether the strings are on a Stradivarius or on Osaki's own $1,200 violin" - Shigeyoshi Osaki


The resonance bodies have to be identical in shape if there is to be no acoustical difference from identical sources of vibration.

The differences heard come the difference resonating bodies, not the vibrating strings.

Long ago a subject of scientific research ... someone innocently posed a harmless sounding question:

Can you hear the shape of an object?

The answer is yes and no.
Why?
Not always the is shape of an object, that is able to vibrate mechanically, unique to the acoustical information that the object is able to provide - another shape will provide identical acoustical information - as far as the resolution resolved by human hearing is concerned.

Yep, it's a serious problem. Lower-middle arp strings are made of organic material (sheep guts), which is why they're must be tuned very often. BTW Why the only smart comment has been downvoted from here? I see, it's because the silly twaddlers don't like it here...

Yes. Unless crystallization occurs while under tension, solids will deform (mostly as elongation) forever until breakage/rupture.

There are self tuning musical strings that exist. The deformation needed to tune these strings is done thermal-electrically.

Commentary threads where all fives exist or no rating at all I like the best.
