The first in a set of three pieces by this composer opens with an E-flat minor theme over triplet arpeggios, (10[1])followed by a restatement in the parallel major. Extremely slow interpretations of the first movement of a late piano sonata by this composer were popularized by Sviatoslav (10[1])Richter, who switched from Bösendorfer to Steinway to record a fantasy by this composer that opens with thundering C major chords (-5[1])in a “long, short-short” rhythm. Brahms edited a set of “three piano pieces” by this composer initially intended to be a third set of four impromptus. This composer (10[1])declared “the devil may play it” in reference to his challenging Wanderer Fantasy. For 10 points, (-5[1])name this German composer (-5[1])whose hundreds of Lieder include (-5[1])settings of Goethe in (10[1])Gretchen at the Spinning Wheel and Der Erlkönig. ■END■ (10[4]0[3])
