This composer's second string quartet ends with the second violin reprising the dotted "Chacony" theme as the other instruments play triple-stopped C major chords. This composer wrote passages of rapidly alternating right- and left-hand pizzicato in the "Scherzo-Pizzicato" movement of his Cello Sonata. This composer used a (10[1])theme from John Dowland's "Flow my tears" as the basis for his Lachrymae for viola (10[1])and orchestra, and he wrote his Cello Symphony and three solo cello suites (10[1])for Mstislav (MIS-tee-slav) Rostropovich. A "Boisterous Bourrée" is followed by a (10[1])"Playful Pizzicato" in this composer's Simple (-5[1])Symphony. This composer featured each of the string instruments in turn during Variations E through H of a piece based on Henry Purcell's (10[1])Rondeau from (10[2])Abdelazer. For 10 points, name this English composer of The Young Person's Guide to (10[2])the Orchestra. ■END■
