Silk strings are still used in most stringed Wagakki (although, for the So, polyester strings are becoming common for economic reasons), and this is because beautiful tones, which can be generated only by silk strings, are highly appreciated.
弦楽器は現在でも絹糸の弦にこだわるが（箏は経済的な事情でポリエステルが多くなった）、これも絹糸でしか出せない音色を尊重するからである。
