A traditional sheet music collection of Ryukyu music, containing 20 songs, in the Kunkunshi format. - Title: Ryukyu Island Song Kunkunshi Volume 1 - Price: Regular price 2,000 yen - Songs: Contains 20 songs - Supervision: Ryukyu Music Score Research Institute - Series: Authentic Ryukyu Folk Song Kunkunshi Thank you for viewing. I recently obtained the "Ryukyu Island Song Ee-Shi" at a Sanshin shop in Okinawa. This "Ee-Shi" is a "limited edition" and was "newly released," so I bought a lot of them. I've 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," supervised it, resulting in a well-made "Ee-Shi." I recommend purchasing this "Ee-Shi" as it's difficult to obtain for those outside of Okinawa Prefecture. The regular price is 2,000 yen (excluding tax), but I purchased it in Okinawa, so I've 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.
