Toshi Ichiyanagi

Toshi Ichiyanagi (一柳 慧 Ichiyanagi Toshi, born 4 February 1933) is a Japanese composer and pianist.

Ichiyanagi was born in Kobe. He studied with Tomojirō Ikenouchi, Kishio Hirao [fr; ja], and John Cage. One of his most notable works is the 1960 composition Kaiki, which combined Japanese instruments, shō and koto, and western instruments, harmonica and saxophone. Another work, Distance (1961), required the performers to play from a distance of three meters from their instruments. Anima 7 (1964) stated that chosen action should be performed "as slowly as possible".

Ichiyanagi was married to Yoko Ono from 1956 to 1963.
