For a piece by this composer, Patricia Kopatchinskaja (“KOH-paht-CHIN-sky-ah”) instructed the orchestra to scream at the end of a cadenza in the Appassionato final movement. This composer almost exclusively used the note A in the first of an eleven-piece collection that ends with an “homage (-5[1])to Girolamo Frescobaldi.” The Aria, Hoquetus, Choral movement of this (15[1])composer’s violin concerto drew from a piano cycle also forming the basis for his (*) Six Bagatelles for Wind Quintet. This composer of Musica Ricercarata (10[1])wrote a “poeme” scored for 100 metronomes. A 1968 film used a piece by this composer that opens with a (-5[1])five-octave tone cluster and employs “micropolyphony.” For 10 points, name this Hungarian composer of Atmosphères, which was used in Stanley Kubrick’s film 2001: A Space Odyssey. ■END■ (0[2])
