Xas is a composition for six percussionists and six wind instruments, composed by Iannis Xenakis in 1987. The piece was premiered on October 16, 1987, at the Théâtre de la Ville in Paris, France. The composition is divided into three movements, each with its own distinct characteristics. The first movement, titled "Metastaseis," is characterized by its use of complex rhythms and intricate polyphonic textures. The percussionists play a variety of instruments, including drums, cymbals, and gongs, while the wind instruments include saxophones, clarinets, and flutes. The movement builds to a frenzied climax before abruptly ending. The second movement, titled "Pithoprakta," is more subdued than the first. It features a series of slow, sustained chords played by the wind instruments, while the percussionists create a series of intricate rhythms using a variety of instruments. The movement gradually builds in intensity before reaching a climax and then fading away. The final movement, titled "Echange," is the shortest of the three. It features a series of call-and-response exchanges between the percussionists and the wind instruments. The percussionists play a series of short, staccato rhythms, while the wind instruments respond with long, sustained notes. The movement ends with a sudden, explosive burst of sound. Overall, Xas is characterized by its use of complex rhythms, intricate polyphonic textures, and a wide variety of percussion and wind instruments. The piece is a testament to Xenakis's innovative approach to composition and his ability to create music that is both challenging and engaging.
