In a piano piece by this composer, increasing rhythmic divisions build into a rapid quintuplet ostinato to depict a chase. That piece by this composer opens with ultra-low clusters imitating “Drums and Pipes.” The last seventeen measures of this composer’s third piano concerto were finished along with his viola concerto (15[1]-5[1])by his student (15[1])Tibor Serly. (15[2]-5[1])This composer’s (15[1])slow movements often (15[1])employ atmospheric (15[1])imitations (15[1])of natural (15[1])sound (15[1])in a (*) “night music” (10[1])style. (10[9]-5[2])An (10[2])“interrupted (10[3])intermezzo” (10[1]-5[1])appears in a piece by this (10[1])composer whose second (10[1])movement assigns different intervals to pairs of instruments. (10[3]-5[1])This “father of (10[1])ethnomusicology” (10[4])used (10[1])an Edison machine to collect (10[2])field (10[2])recordings with his compatriot Zoltán Kodály. (10[4])For 10 points, name this Hungarian composer (-5[1])of a Concerto (-5[1])for Orchestra. (10[3])■END■ (10[9]0[4])
