Mizu no Hentai 水の変態 – Michio Miyagi (1908)
During the summer when he was aged 13, Michio moved to Incheon in Korea. He supported his family by teaching koto in daytime and Shakuhachi in the evening. At 14 he composed his first work “Mizu no Hentai”. With this composition, Michio became recognized by Hirobumi Itoh who promised to bring Michio to Tokyo and support him. Soon after, however, Itoh was assassinated so that the promise to Michio could never be carried out.
Miyagi’s first extant composition, written shortly before his fifteenth birthday in 1909, is “Mizu no Hentai” (Transformations of Water). Miyagi was inspired to write this piece after hearing his brother recite a school textbook poem by the same name which described seven states of water; mist, clouds, rain, snow, hail, dew, and frost. The form of “Mizu no Hentai”, with its alternating vocal and instrumental sections, is unlike any used in koto music until that time. While no new playing techniques are found, they are used at exceptional tempo and in unprecedented patterns, and the left hand is used extensively to play multiple pitches simultaneously. In his writings, Miyagi said that he wanted to write a new style of koto music because “Most of the –compositional- forms used in koto music were created long ago, and besides it is monotonous. I wanted to create music where two or three notes were played at a time, more complicated things like in Western music.”
“Mizu no Hentai” was first performed at a concert in Seoul about two months after it was composed. Miyagi himself added a kaede, or part for a second player, around 1917. While the original solo version of “Mizu no Hentai” is a technical masterpiece, it becomes even more so when played with the kaede as a duet. When listening to the two parts performed together it is virtually impossible to tell which player is playing which line. Both the solo and duet versions of “Mizu no Hentai” are widely performed today and the work has become a standard of the koto repertoire.
