Kunkunshi (工工四 (Okinawan) pronounced [kuŋkunɕiː]) is the traditional notation system by which music is recorded in the Ryukyu Islands.
[1] Kunkunshi is believed to have been first developed by Mongaku Terukina or by his student Choki Yakabi [ja] in the early to mid-1700s.
However, it was not until the end of the 19th century that the form became standardized for writing sanshin music.
The Yakabi Kunkunshi consists of 117 compositions written in the kaki nagashi style.
In this form, the sanshin finger positions are written in a flowing style with no indication of rhythm.
