An orchestral work by this composer begins with a quick exchange between the bass section and a solo oboe and viola. A cantata by this composer ends with a thrice-repeated four-part canon on text that translates as “Loosened from the womb.” This composer omitted double basses from his only symphony, whose second and final part is a set of variations. (10[1])Early (10[1])works by this composer include a Passacaglia for orchestra (10[1])and the tone poem Im Sommerwind (10[5])(“imm ZOAM-er-vint”). This composer’s (10[1])innovative and sparse orchestration of Bach’s Ricercar (10[1])a 6 (“ree-cher-KAR ah say”) from The Musical Offering (10[1])extended his mentor’s technique of (10[1])Klangfarbenmelodie. This composer collaborated with Hildegard Jone (“YO-nuh”) to write two cantatas, the second of which, at 15 minutes, is his longest (10[2])composition. For 10 points, name this student of Schoenberg, the most radical (10[1])composer (10[1])of the Second Viennese (10[1])School. (10[1])■END■ (10[3])
