The influence of Olivier Messiaen on Takemitsu was already apparent in some of Takemitsu's earliest published works. By the time he composed Lento in Due Movimenti, (1950), Takemitsu had already come into possession of a copy of Messiaen's 8 Preludes (through Toshi Ichiyanagi), and the influence of Messiaen is clearly visible in the work, in the use of modes, the suspension of regular metre, and sensitivity to timbre. Throughout his career, Takemitsu often made use of modes from which he derived his musical material, both melodic and harmonic among which Messiaen's modes of limited transposition to appear with some frequency. In particular, the use of the octatonic, (mode II, or the 8-28 collection), and mode VI (8-25) is particularly common. However, Takemitsu pointed out that he had used the octatonic collection in his music before ever coming across it in Messiaen's music.  In 1975, Takemitsu met Messiaen in New York, and during "what was to be a one-hour 'lesson' [but which] lasted three hours ... Messiaen played his Quartet for the End of Time for Takemitsu at the piano", which, Takemitsu recalled, was like listening to an orchestral performance. Takemitsu responded to this with his homage to the French composer, Quatrain, for which he asked Messiaen's permission to use the same instrumental combination for the main quartet, cello, violin, clarinet and piano (which is accompanied by orchestra). As well as the obvious similarity of instrumentation, Takemitsu employs several melodic figures that appear to "mimic" certain musical examples given by Messiaen in his Technique de mon langage musical, (see ex. 4). In 1977, Takemitsu reworked Quatrain for quartet alone, without orchestra, and titled the new work Quatrain II.  On hearing of Messiaen's death in 1992, Takemitsu was interviewed by telephone, and still in shock, "blurted out, 'His death leaves a crisis in contemporary music!'" Then later, in an obituary written for the French composer in the same year, Takemitsu further expressed his sense of loss at Messiaen's death: "Truly, he was my spiritual mentor ... Among the many things I learned from his music, the concept and experience of color and the form of time will be unforgettable." The composition Rain Tree Sketch II, which was to be Takemitsu's final piano piece, was also written that year and subtitled "In Memoriam Olivier Messiaen".
