ヤニス・クセナキスのサクソフォン作品といえば「XAS」。
その他に、オーボエとパーカッションのために書かれ、後に作曲家自身により公式にソプラノサクソフォン向けに書き直された「Dmaathen」なる作品があるそうな。知らなかった…。ちゃんとロンデックス本にも記載があった。
www.amusicalfeast.comの解説を引用。曲の流れの言及がほとんどだが。
Dmaathen is presented as it was originally scored for oboe and percussion. Subsequent
revisions of the piece, by the composer, restructured the oboe part for flute and for soprano
saxophone. The piece is presented in two large sections. In the first, drum outbursts sit atop
a soundscape of oboe multi-phonics; the second features declamatory and almost humorous
march-like passages from both instruments. These two large parts are framed with a short
introduction (with slinky sax lines and tribal drum sounds) and a short coda (with a stately
dialogue between the oboe and vibraphone). From there, this visceral and abstract piece
quickly fades into silence.
