Sheet music collection of Kunkunshi (notation used in Ryukyu music) featuring traditional Ryukyu music. - Title: Ryukyu Island Song Kunkunshi Volume 1 - Price: 2500 yen - Number of songs: 20 - Supervision: Ryukyu Music Score Research Institute Thank you for viewing. This is the "Ryukyu Island Song Ee-Shi" I recently obtained at a Sanshin shop in Okinawa. This "Ee-Shi" is a "limited edition" and was "newly released," so I purchased a large quantity and have decided to sell some of them on Mercari. After checking the contents, as expected, the "Ryukyu Music Score Research Institute," which produces the "Ryukyu Folk Song Ee-Shi," has supervised it, resulting in a well-made "Ee-Shi." I recommend purchasing this "Ee-Shi" as it is difficult for those outside of Okinawa Prefecture to obtain. The regular price is ￥2,500 (excluding tax), but I purchased it in Okinawa, so I have slightly increased the price. Please consider purchasing a copy. Note: This is a defective copy, so please refrain from purchasing if you are sensitive to such issues. This book has some binding irregularities. The contents are intact. This price is firm. Please comment if you are interested.
