René Leibowitz cited a piece by this composer that begins with the spoken line “I cannot remember everything. I must have been unconscious” (10[1])as an example of music that meets the requirements of “committed art.” This composer’s early use of quartal harmony can be heard in an ascending theme first played by the horn in his first Chamber Symphony. This composer began using an athematic style in his Opus 11 Drei Klavierstücke (“DRY klah-vee-AIR-shtuck-uh”), and he also wrote A Survivor from Warsaw. The title character (10[1])is called “drunk” in the opening section of a song cycle by this composer (10[1])that is accompanied (10[1])by a namesake ensemble and pioneered the technique of Sprechstimme. For 10 points, name this Austrian composer of Pierrot Lunaire (10[1])who developed 12-tone (10[1])serialism. ■END■
