Eclipse (Takemitsu): Before Takemitsu started to compose "Eclipse", he was reticent to use Japanese traditional instruments, because, as he puts it, their sound "always recalled the bitter memories of war".  He started to use these instruments in 1962 Masaki Kobayashi's "Harakiri".  Since this first collaboration, Takemitsu started using these instruments more often, as seen in Shinoda's "Assassination" and Masaki Kobayashi's "Kwaidan".  He finally composed "Eclipse" in 1966 and premiered it that same year with Kinshi Tsuruta at the biwa and Katsuya Yokoyama at the shakuhachi.  The premiere took place in the Nissei Theater, in Tokyo, on May 4, 1966.  It is published by Éditions Salabert and has received a catalogue number W43 by James Siddons.
