Violin strings from the web

Tool with new strings, according to experts, demonstrated the "soft and deep voice" sound. Some violinists even started talking about a "new music."


The inventor of the spider strings — Sigeesi Osaka (Shigeyoshi Osaki) from Nara Medical University (Nara Medical University). According to PhysOrg.com, this scientist, a specialist in polymer chemistry for 35 years working on a study of spider silk and the technology of large-scale extract the strong threads.

These natural fibers have the potential to be an interesting material for body armor or surgical sutures. But no one else seems to think out of the webs to make strings for musical instruments. Osaka, and he plays the violin, decided to fill this gap.

The Japanese took advantage of using the Spider 300 Nephila maculata, reared in captivity. Threads of Dr. Osaka wove them into bundles for 3000 and 5000 pieces. Of three such bundles are twisted in the opposite direction, to create their own strings for violin.

Testing of tensile strength showed that the "spider" string kept a somewhat lower voltage than the occasional string of guts, but is much more common than the strings of nylon and aluminum coating. Exploring cut the strings under the electron microscope showed that they have an important difference from peers. While in conventional strings Interlaced fibers retain a circular shape, leaving a lot of empty space between them, the spider thread polygons acquired form tightly assembled together.

According Sigeesi, it is one of the important factors that give new strings not only the strength and resilience, but also specific sound (specific overtones), which musicians can easily distinguish by ear.


On his reaching Osaka explained in Physical Review Letters, noting that the experience with the strings will help promote experiments in unusual materials in general.
