The 80-string Шаблон:Transliteration was largely hand-constructed, as only limited machinery existed to manufacture it. It was built along similar lines to the common Шаблон:Transliteration, but with reinforced design elements; for instance, the platform where strings are tied runs the entire length and breadth of the instrument to accommodate the increased strain.
As with other Шаблон:Transliteration, the Paulownia wood used for the instruments' body (Paulownia tomentosa, known as Шаблон:Transliteration in Japanese) is molded and treated.Шаблон:How The bridges of the Шаблон:Transliteration, known as Шаблон:Transliteration, are often made of plastic in the modern day, and can be found in both small and large sizes. These bridges are rearranged as needed during playing, and are arranged according to the particular tuning used. Strings are traditionally made from silk threads, although plastic nylon strings are often used as a cheaper alternative.
Usage
The 80-string Шаблон:Transliteration is not widely used. There are few extant examples of the instrument today, as it never achieved the popularity of the 17-string koto, Miyagi's more widely accepted invention.
